------------------------------------------ LAN Manager 2.2B--Patch to LAN Manager 2.2 ------------------------------------------ CONTENTS ======== 1.0 Introduction 2.0 LAN Manager 2.2B Patch Installation Instructions 2.1 User Notes 2.2 Bugs Fixed in the LAN Manager 2.2B Release 2.3 Text of Bug Fixes 1.0 INTRODUCTION ================ This release of LAN Manager 2.2B contains all components that have been fixed since the original release of LAN Manager 2.2. 2.0 LAN Manager 2.2B Patch Installation Instructions ==================================================== For OS/2 -------- 1. Type NET STOP WKSTA at an OS/2 command prompt. 2. Detach LAN Manager using the LAN Manager Setup utility on the hard disk. 3. Reboot the system. 4. Once the system has rebooted, insert LAN Manager 2.2B OS/2 Patch Disk 1 into the floppy drive. 5. At an OS/2 command prompt, change to that floppy drive (that is, A: or B:) and type SETUP. 6. Follow the instructions given on the screen. For MS-DOS ---------- 1. Insert LAN Manager 2.2B DOS Patch Disk 1 into the floppy drive. 2. At an MS-DOS command prompt, change to that floppy drive (that is, A: or B:) and type SETUP. 3. Follow the instructions given on the screen. 2.1 User Notes -------------- Note One: Problem Loading LM 2.2b NETWKSTA.EXE into MS-DOS 6.2 UMBs ------------------------------------------------------------------- When you install the LAN Manager 2.2b Patch onto MS-DOS 6.2, the NETWKSTA.EXE is not correctly loaded into the upper memory blocks (UMBs) because LAN Manager initialization incorrectly processes the version number of MS-DOS 6.2. Make sure that there is adequate contiguous UMB space to accommodate the redirector. Do not load SMARTDRV or other drivers and utilities into the UMB prior to starting the workstation. Many personal computers have UMB space available in the E000 segment (verify that ROM and shared memory devices are not located in this region). To make this memory region available use I=E000-EFFF as an option for EMM386.EXE in CONFIG.SYS. If you do not need expanded memory (EMS) use NOEMS as an EMM386.EXE option to save the 64k page frame for EMS support. Example line in CONFIG.SYS Device=C:\WINDOWS\EMM386.EXE NOEMS I=E000-EFFF Microsoft has confirmed this to be a problem and is testing a possible fix. Contact Microsoft Product Support Services for its status and availability. New information will be posted in the Microsoft Knowledge Base as it becomes available. Note Two: MS-DOS Low Density Install Diskettes not Available. ------------------------------------------------------------- The low density MS-DOS client patch install diskettes are not available. Here is a procedure for installing the Patch on a network workstation with a 360k floppy drive(s). 1. NET SHARE a directory on a network file server. 2. Copy all files on the LAN Manager 2.2b MS-DOS Patch high density disk to the shared directory. 3. Connect to this share from the workstation that you want to upgrade with the NET USE command. 4. Apply the patch to the workstation by running SETUP.EXE from the shared directory. Note Three: OS/2 Drivers and Files Included with Patch. ------------------------------------------------------- Updated versions of the following OS/2 files are included with this patch: - PMSPL.DLL - PSCRIPT.DRV - PMSPL.EXE - OS2KRNL These files are not automatically installed. To install these files on a OS/2 computer you must manually decompress and replace them. Use the command DECOMP to decompress the files. Use File Manager to change attributes, rename, and copy over these files. For an example, following are the steps to replace OS2KRNL: 1. Decompress the file using the command DECOMP. 2. Open File Manager. 3. Choose View, then Include, then File Flags. Select Show Read-Only, Archive, Hidden, and Other. 4. Choose the C: drive, then highlight OS2KRNL. 5. Choose File, Change Flags, deselect the Read Only, Archive, Hidden, and System flags, and click on Change. 6. Rename the file OS2KRNL to OS2KRNL.OLD. 7. Copy the new OS2KRNL from the floppy disk, and highlight it in File Manager. 8. Choose File, then choose Change Flags. Select the Read Only, Archive, Hidden, and System flags, then click on Change. The following third party manufacturer's .BID drivers are also supplied with this patch: - Adaptec 174x - CPQC710 - Ultra24f They are installed as above. These drivers are manufactured by third party vendors independent of Microsoft; we make no warranty, implied or otherwise regarding these drivers' performance or reliability 2.2 Bugs Fixed in the LAN Manager 2.2B Release ============================================== - Printsta Fails, Hangs MS-DOS Workstation When Printscreen Starts - More Than 32 Domain Controllers on a Domain Causes PDC GP Fault - Ill-Formed SMB From Client Causes Server to Die or GP Fault - Workstation Hangs After Period of Copying or Running HLAPI Code - Net Logon on MS-DOS Client Not Validated by Server - Attempt to Stop/Restart PDC Locks out BDC if No One Logged On - WinAdmin Creates Too Many ACL Entries, Making NET.ACC Too Big - FAT Server Stops Responding if Same Byte Range Repeatedly Locked - Replicator Copies Files Already in Sync or for HPFS386 Importer - API Call Holds Semaphores After Access Check on Non-Existent File - Later Logon Scripts Fail After Time-out Occurs When Logon Running - BACKACC Failure from AT Command Required Server Stop/Restart - NetBEUI Needs SRB On/Off Switch with 3Com NetBuilder SRT Bridge - FTBOOT Causes Trap D/Trap C When Recovering Boot Volume Mirror - Core Drive Error Causes Multiple Errors and Data Corruption - Failure of Network Request During Logon Hangs Time-out Period - MS-DOS Enhanced Workstation Runs Out of Netbufs and Hangs - File Seek Fails After Buffer Flushing Error on Seek Initiation - Net Password Command During Sync Deadlocks Server and Netlogon - WS Hangs Running TCP/IP, DLC and Windows Enh on IBM Token Ring - WfW Workstation Cannot Run FoxPro after a LM Workstation Does - Application Produces Occasional NET808 and NET805 Errors - Windows NetBIOS App Encounters SYS3175 Trap Under OS/2 2.0 - System Hangs or Reboots Accessing File on Disconnected Drive - NET LOGOFF /Y Returns NET2402 if Files Open on a Connection - NETWKSTA.EXE Won't Run with MS-DOS 6.0 Without SETVER - Password Displayed in Share Info Dialog when Server Share-level - More than 300 Entries in RPL.MAP Causes RPLMGR to Trap 000d - NET STOP RDR /Y Followed by NET START RDR Hangs MS-DOS Client - Period ( . ) Not a Valid Character in Workstation Names - Logon Starts Failing after 16 Logons with a Logon Script - Running Local and Remote I/O Stress Tests Caused GP Fault - DosPeekNmPipe Call Returns Too Much Data, Causes Broken Pipe - SQL Queries Under RAS Cause Lock-up, Reboot or EMM Exception #06 - Full Sync Initiated by Small Netlogon Service Buffer Request - LM Setup Does Not Recognize IBM DOS 5.02 as Valid DOS Version - Netlogon Service Encounters GP Fault as Array Memory is Overrun - DOSPeekNmPipe API Returns Incorrect Byte Count for Its Buffer - Issuing CTRL-C as BACKACC Writes to Hard Disk Causes GP Fault - OS/2 Server Hangs if Network Adapter Cannot Reset - Duplicate Name and Net Address on Token Ring Crashes Server - MS-DOS Applications Incorrectly Report "0 Bytes Free" - RESTACC Fails with "SYS0111 File Name Too Long" Error - Badly Formed Server Message Block Sent to Server Causes Trap - Netlogon Performs Continuous Full Synchronization - UPS Service Fails Compaq ProSignia if Low Battery Signal Enabled - Windows Hangs or Crashes to MS-DOS Prompt If Running Many Apps - Workstation Hangs with NET 805, Server Records Incomplete NCB Error - Trap D Occurs With HPFS386 when ATTRIB *.TXT /S is Entered - Trap D in TCPNB$ - DOS TCP/IP Clients get Logged on Standalone Despite DC Responses - TCP/IP Server Won't Send Datagrams; BDCs Go Out of Sync - BCASTADDR Parameter in PROTOCOL.INI Ignored by OS/2 TCP/IP - All TCP/IP Servers on Net Trap in NBDRV.0S2 - Server Crashes and Issues TRAP 0003 - Sybase Server Doesn't Respond to TCP/IP "Cancel" Commands - TCP/IP MS-DOS Utilities Cannot Connect with IBM 3090 MVS - Information Packets Incorrectly Reassembled After Crossing Router - TCP/IP Returns Wrong Error Code on Failed Call - LM Server Trap D's in TCPDRV When Sent LLC XID - TCP/IP Server Routes Traffic from Token Ring to Ethernet, Crashes - Error 53--TCPCONNECTIONS Depleted, Connection Denied to Client 2.3 Text of Bug Fixes --------------------- ---------------------------------------------------------------- Printsta Fails, Hangs MS-DOS Workstation When Printscreen Starts ---------------------------------------------------------------- CSD: LM22.CSD01.037 SYMPTOMS ======== Printsta failed. If the user on an MS-DOS workstation attempted to perform print screen operations, the workstation operated properly until printscreen was initiated, then would hang. RESOLUTION ========== The timer stack was getting corrupted, so the size of the stack was increased. Also, some of the retry logic was changed so that on slow PCs requests no longer time out. Binary Affected --------------- PRINTSTA.EXE --------------------------------------------------------------- More Than 32 Domain Controllers on a Domain Causes PDC GP Fault --------------------------------------------------------------- CSD: LM22.CSD01.040 SYMPTOMS ======== The addition of more than 32 domain controllers (primary and backup) on a domain caused a GP Fault on the primary domain controller. RESOLUTION ========== The number of combined members (backup and primary domain controllers) allowed in a domain was changed from 32 to 128. A check was also added that keeps the primary domain controller from faulting if more than 128 domain controllers are added to the domain (although an error still is logged). Binary Affected --------------- NETLOGON.EXE NETAPI.DLL ----------------------------------------------------------- Ill-Formed SMB From Client Causes Server to Die or GP Fault ----------------------------------------------------------- CSD: LM22.CSD01.041 SYMPTOMS ======== An ill-formed server message block from a client sometimes caused the server to either GP fault or "go dead." RESOLUTION ========== The manner in which ill-formed server message blocks are handled was changed. Specifically, code was added that put a null at the end of their truncated or corrupted strings. Binary Affected --------------- HPFS386.IFS HPFS.386 --------------------------------------------------------------- Workstation Hangs After Period of Copying or Running HLAPI Code --------------------------------------------------------------- CSD: LM22.CSD01.042 SYMPTOMS ======== After 15 minutes of activity such as copying files between a server and a workstation or running Attachmate HLAPI code that polls the server, the workstation would hang. RESOLUTION ========== The MS-DOS redirector stack was overflowing. Stack size was increased. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 -------------------------------------------------- Net Logon on MS-DOS Client Not Validated by Server -------------------------------------------------- CSD: LM22.CSD01.043 SYMPTOMS ======== A net logon on an MS-DOS client sometimes resulted in a standalone logon--the server refused to validate it. RESOLUTION ========== If the name-query packet was larger than usual (that is, if an additional field in the resource record was filled in) then a routine in TINYRFC.EXE failed to free a buffer. The code was modified to assure that the buffer is freed. Binary Affected --------------- TINYRFC.EXE ------------------------------------------------------------- Attempt to Stop/Restart PDC Locks out BDC if No One Logged On ------------------------------------------------------------- CSD: LM22.CSD01.044 SYMPTOMS ======== When no one was logged on at the backup domain controller and the primary domain controller was stopped and started, the backup attempted to connect to the primary using its computer name and some unknown password. This repeated, causing two effects: - the account was locked out (if lockout was set up) - the audit log was filled with spurious bad password attempts Netlogon synchronization was not affected. RESOLUTION ========== Code was changed so that a backup domain controller no longer attempts a single API if there is no one logged on: it simply gets the next request. This does not lessen functionality, as these calls would fail in any case, but it makes the failures local so they are not logged. Binary Affected --------------- NETLOGON.EXE ------------------------------------------------------------- WinAdmin Creates Too Many ACL Entries, Making NET.ACC Too Big ------------------------------------------------------------- CSD: LM22.CSD00.002 SYMPTOMS ======== WinAdmin's "permit tree" feature incorrectly walked the directory tree and created ACL entries for each file and for its subdirectory, quickly causing NET.ACC to become huge. RESOLUTION ========== Code was changed to create ACL entries only for subdirectories and to delete any existing ACL entries for files. The change also displays both explicit and inherited permissions. Binary Affected --------------- NETADMIN.EXE ---------------------------------------------------------------- FAT Server Stops Responding if Same Byte Range Repeatedly Locked ---------------------------------------------------------------- CSD: LM22.CSD00.003 SYMPTOMS ======== When the same byte-range was repeatedly locked, a FAT server stopped responding after some number of lock attempts. RESOLUTION ========== Code was changed to correct time-out determination. Binary Affected --------------- NETSERVR.EXE --------------------------------------------------------------- Replicator Copies Files Already in Sync or for HPFS386 Importer --------------------------------------------------------------- CSD: LM22.CSD00.004 SYMPTOMS ======== The replicator copied files already in sync from subdirectories that contained large numbers of files, and when the importer had an HPFS386 disk. RESOLUTION ========== A larger buffer size was implemented in the replicator code. Binary Affected --------------- REPLCLI.EXE ----------------------------------------------------------------- API Call Holds Semaphores After Access Check on Non-Existent File ----------------------------------------------------------------- CSD: LM22.CSD00.005 SYMPTOMS ======== Checking the access on a file that did not exist (on a FAT partition) caused the API call to take but not release three semaphores. RESOLUTION =========== Code was changed so that it now sets the correct error and frees the semaphores before returning. Binary Affected --------------- NETAPI.DLL ----------------------------------------------------------------- Later Logon Scripts Fail After Time-out Occurs When Logon Running ----------------------------------------------------------------- CSD: LM22.CSD00.006 SYMPTOMS ======== If a Windows logon script was still running when the logon script time-out occurred, all subsequent logon scripts failed until Windows was exited. RESOLUTION ========== A variable that checks the time-out in a DLL was set to initialize each time the routine is called. Binary Affected --------------- NETAPI.DLL (Win16 version) ------------------------------------------------------------ BACKACC Failure from AT Command Required Server Stop/Restart ------------------------------------------------------------ CSD: LM22.CSD00.007 SYMPTOMS ======== BACKACC failed to complete when run from the AT command, and could not be run by AT again until the server was stopped and started. RESOLUTION ========== The server had too many open files, since remote APIs were not closing the UASCHG.LOG file once it was opened. Code was changed to close this file after each open. Binary Affected --------------- NETAPI.DLL --------------------------------------------------------------- NetBEUI Needs SRB On/Off Switch with 3Com NetBuilder SRT Bridge --------------------------------------------------------------- CSD: LM22.CSD00.008 SYMPTOMS ======== With the 3Com NetBuilder SRT Bridge, NetBEUI required a switch to turn instant flipping of the source routing bit on and off. RESOLUTION ========== Added [NETBEUI_XIF] parameter, LocalRing, which is 0 by default. When this is zero, the source routing bit is turned on immediately. When it is 1, it allows the packet to traverse the local ring three times before the SRB is turned on. Binary Affected --------------- NETBEUI.* -------------------------------------------------------------- FTBOOT Causes Trap D/Trap C When Recovering Boot Volume Mirror -------------------------------------------------------------- CSD: LM22.CSD00.010 SYMPTOMS ======== FTBOOT caused a Trap D or Trap C when trying to recover the boot volume mirror. RESOLUTION ========== Code was changed to clear the extended partition record if the boot volume mirror is the only partition on its disk. Binary Affected --------------- FTBOOT.EXE ----------------------------------------------------------- Core Drive Error Causes Multiple Errors and Data Corruption ----------------------------------------------------------- CSD: LM22.CSD00.011 SYMPTOMS ======== The core drive issued an error code which the BID handled incorrectly, causing multiple errors and data corruption. This affected other SCSI drives attached to an IBM SCSI adapter, not just the core drives. RESOLUTION ========== This was fixed by causing the BID to set a timer and simulate an interrupt, which allows it to handle the error condition correctly. Binary Affected --------------- ABIOS.BID ------------------------------------------------------------- Failure of Network Request During Logon Hangs Time-out Period ------------------------------------------------------------- CSD: LM22.CSD00.012 SYMPTOMS ======== In Windows, failure of a network request during a logon attempt (such as attempting to connect to a down server) caused the time-out period to hang for an excessively long time. RESOLUTION ========== Changed the logic to use a count to check for the elapsed time since the dialog was started and to abort the logon script based on this. Binary Affected --------------- NETAPI.DLL (Win16 version) --------------------------------------------------------- MS-DOS Enhanced Workstation Runs Out of Netbufs and Hangs --------------------------------------------------------- CSD: LM22.CSD00.014 SYMPTOMS ======== MS-DOS enhanced workstations would run out of netbufs and hang. RESOLUTION ========== Code was changed so that the terminating loop case no longer became incorrect. The MS-DOS redirector is now guaranteed not to run out of work buffers. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 -------------------------------------------------------------- File Seek Fails After Buffer Flushing Error on Seek Initiation -------------------------------------------------------------- CSD: LM22.CSD00.015 SYMPTOMS ======== File seeks failed if there was an error flushing a buffer when the seek was initiated. RESOLUTION ========== This was fixed by correcting the stack manipulation. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 -------------------------------------------------------------- Net Password Command During Sync Deadlocks Server and Netlogon -------------------------------------------------------------- CSD: LM22.CSD00.016 SYMPTOMS ======== Issuance of a net password command while a domain controller (backup or primary) was performing a full sync caused a deadlock that kept part of the server and part of Netlogon from functioning. Domain controllers made no progress syncing, the net password command stopped functioning, and the Netlogon process that gets and responds to requests would hang. RESOLUTION ========== The code was changed to fix the logic code so that the Netlogon process releases its semaphore before requesting the server's semaphore. Binary Affected --------------- NETAPI.DLL -------------------------------------------------------------- WS Hangs Running TCP/IP, DLC and Windows Enh on IBM Token Ring -------------------------------------------------------------- CSD: LM22.CSD00.017 SYMPTOMS ======== Workstations running TCP/IP, DLC, and Windows Enhanced mode with an IBM token ring card would randomly hang. RESOLUTION ========== The stack usage of the token ring driver was changed to alleviate the problem. Binary Affected --------------- IBMTOK.DOS ----------------------------------------------------------- WfW Workstation Cannot Run FoxPro after LM Workstation Does ----------------------------------------------------------- CSD: LM22.CSD00.018 SYMPTOMS ======== When a LAN Manager workstation was running a FoxPro application on a LAN Manager server, a Windows for Workgroups workstation that tried to run the FoxPro application received: Network Error Reading Drive X: followed by: File Read Error When a Windows for Workgroups workstation initialized the FoxPro application with a database file 2K or larger, both the first and the second workstations received the error messages. RESOLUTION ========== The FAT file server was changed so that it now correctly sets two fields in a server message block sent to the Windows for Workgroups client. Binary Affected --------------- NETSERVR.EXE -------------------------------------------------------- Application Produces Occasional NET808 and NET805 Errors -------------------------------------------------------- CSD: LM22.CSD00.019 SYMPTOMS ======== An application produced occasional NET808 and NET805 errors during command processing. RESOLUTION ========== Buffer flushing code was changed to correct this. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 ---------------------------------------------------------- Windows NetBIOS App Encounters SYS3175 Trap Under OS/2 2.0 ---------------------------------------------------------- CSD: LM22.CSD00.020 SYMPTOMS ======== A Windows NetBIOS application encountered a SYS3175 trap while issuing a listen. The application worked correctly under Win 3.1 but not in the Win 3.1 environment under OS/2 2.0. RESOLUTION ========== OS/2 was not handling the call correctly. A workaround was implemented in NETVDD. Binary Affected --------------- NETVDD.SYS ------------------------------------------------------------ System Hangs or Reboots Accessing File on Disconnected Drive ------------------------------------------------------------ CSD: LM22.CSD00.021 SYMPTOMS ======== The system would hang or reboot when trying to access a file in a Windows application on a disconnected drive when Windows was being run over the net, usually in a token ring environment. RESOLUTION ========== The program was running out of network buffers. Code was changed to add checks to the code path that retrieves buffers. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 ----------------------------------------------------------- NET LOGOFF /Y Returns NET2402 if Files Open on a Connection ----------------------------------------------------------- CSD: LM22.CSD00.022 SYMPTOMS ======== The command NET LOGOFF /Y returned the error NET2402 if files were open on a connection. Subsequent attempts returned the same error. RESOLUTION ========== The system file table entry is now marked as invalid, allowing the command to complete. Applications receive an error if they try to access an open file's handle. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 ----------------------------------------------------- NETWKSTA.EXE Won't Run with MS-DOS 6.0 Without SETVER ----------------------------------------------------- CSD: LM22.CSD00.024 SYMPTOMS ======== NETWKSTA required the use of SETVER to run with MS-DOS 6.0. RESOLUTION ========== Code was changed. NETWKSTA now allows MS-DOS 6.0. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 --------------------------------------------------------------- Password Displayed in Share Info Dialog when Server Share-level --------------------------------------------------------------- CSD: LM22.CSD00.026 SYMPTOMS ======== Password is displayed in share info dialog when server is share-level. RESOLUTION ========== This has been corrected so that a read-only clear-text share password is displayed if the server is share-level. If you choose OK without changing anything, the system deletes the password on the share, leaving it blank. Binary Affected --------------- NETADMIN.EXE ----------------------------------------------------------- More than 300 Entries in RPL.MAP Causes RPLMGR to Trap 000d ----------------------------------------------------------- CSD: LM22.CSD00.027 SYMPTOMS ======== If the RPL.MAP file had more than 300 entries, RPLMGR issued Trap 000d on startup. After a workstation beyond number 300 was added, refreshing the workstation list or exiting and re-entering RPLMGR caused the program to Trap 000d. Session Title: RPLMGR.EXE SYS1943:A program caused a protection violation. TRAP 000D AX=0296 BX=EAF0 CX=0000 DX=1BF7 BP=1D90 SI=052A DI=0000 DS=1957 ES=1BCF FLG=2212 CS=18F7 IP=07D8 SS=01C7 SP=1D8A MSW=001B CSLIM=07F2 SSLIM=1FFF DSLIM=0CEF ESLIM=F019 CSACC=FB SSACC=F3 DSACC=F3 ESACC=F3 ERRCD=0000 ERLIM=**** ERACC=** RESOLUTION ========== Memory re-allocation code was modified so that the size of the memory block now is calculated correctly. Binary Affected --------------- RPLMGR.DLL ------------------------------------------------------------- NET STOP RDR /Y Followed by NET START RDR Hangs MS-DOS Client ------------------------------------------------------------- CSD: LM22.CSD00.030 SYMPTOMS ======== Performing NET STOP RDR /Y followed by NET START RDR sometimes hung an MS-DOS client or caused it to hang a few seconds after returning from the commands. RESOLUTION ========== Code was changed to handle cases wherein no protocols are loaded and the network card NDIS driver is sending a packet up to the protocol. Binary Affected --------------- PROTMAN.DOS PROTMAN.EXE ------------------------------------------------------- Period ( . ) Not a Valid Character in Workstation Names ------------------------------------------------------- CSD: LM22.CSD00.031 SYMPTOMS ======== Workstation names could not include '.' as a character. RESOLUTION =========== The list of valid characters for workstation names was changed to include the period ( . ). Binary Affected --------------- NETADMIN.EXE -------------------------------------------------------- Logon Starts Failing after 16 Logons with a Logon Script -------------------------------------------------------- CSD: LM22.CSD00.037 SYMPTOMS ======== Under Windows, logging in and out with a logon script 16 times in a row caused the logon to start failing. RESOLUTION ========== The LMSCRIPT.$$$ flag file was being left open after logon script processing, so that after about 16 logons too many files were open. Changes in code cause the file to be closed now before it is deleted. Binary Affected --------------- NETAPI.DLL --------------------------------------------------------- Running Local and Remote I/O Stress Tests Caused GP Fault --------------------------------------------------------- CSD: LM22.CSD00.038 SYMPTOMS ======== Running a local and a remote I/O stress test simultaneously caused a GP fault. RESOLUTION ========== Code was changed to allow HPFS386 and the LM OS/2 redirector to share a field in a common structure. Binary Affected --------------- NETWKSTA.SYS ------------------------------------------------------------ DosPeekNmPipe Call Returns Too Much Data, Causes Broken Pipe ------------------------------------------------------------ CSD: LM22.CSD00.040 SYMPTOMS ======== The OS/2 redirector returned more data than an MS-DOS client machine could handle in response to a DosPeekNmPipe call. The underlying transport returned error 06h (Incomplete Received Message) to the MS-DOS redirector on a RECEIVE ANY, causing it to hang the session and result in a broken pipe. RESOLUTION ========== Code was changed to correct circular buffer handling. Binary Affected --------------- NETWKSTA.SYS ---------------------------------------------------------------- SQL Queries Under RAS Cause Lock-up, Reboot or EMM Exception #06 ---------------------------------------------------------------- CSD: LM22.CSD00.041 SYMPTOMS ======== During SQL queries under RAS the machine would occasionally lock-up, reboot, or report EMM Exception #06. RESOLUTION ========== The redirector's internal critical stacks were too small and were getting overrun when RAS would back up NCB processing. The stacks were amended to alleviate the problem. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 ------------------------------------------------------------ Full Sync Initiated by Small Netlogon Service Buffer Request ------------------------------------------------------------ CSD: LM22.CSD00.042 SYMPTOMS ======== For groups with large numbers of users, the Netlogon service was not asking for a buffer large enough to contain all users, resulting in a full sync between domain controllers. RESOLUTION ========== A larger buffer has been allocated for this request. Binary Affected --------------- NETLOGON.EXE ------------------------------------------------------------- LM Setup Does Not Recognize IBM DOS 5.02 as Valid DOS Version ------------------------------------------------------------- CSD: LM22.CSD00.044 SYMPTOMS ======== The LAN Manager Setup program did not recognize IBM DOS 5.02 as a valid DOS version. RESOLUTION ========== Checks were added for this DOS version. Binary Affected --------------- SETUP.EXE --------------------------------------------------------------- Netlogon Service Encounters GP Fault as Array Memory is Overrun --------------------------------------------------------------- CSD: LM22.CSD00.045 SYMPTOMS ======== The Netlogon Service was ending in a GP fault when memory usage for an array was overrun. RESOLUTION ========== Larger allocations were made for the array. Binary Affected --------------- NETLOGON.EXE NETAPI.DLL ------------------------------------------------------------- DOSPeekNmPipe API Returns Incorrect Byte Count for Its Buffer ------------------------------------------------------------- CSD: LM22.CSD00.046 SYMPTOMS ======== The DOSPeekNmPipe API returned an incorrect count for the number of bytes in its buffer. RESOLUTION ========== This was caused when the DOSPeekNmPipe API did not initialize correctly under certain circumstances. It has been changed so that it now initializes the number of bytes read to the correct value. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 ------------------------------------------------------------- Issuing CTRL-C as BACKACC Writes to Hard Disk Causes GP Fault ------------------------------------------------------------- CSD: LM22.CSD00.047 SYMPTOMS ======== Issuing CTRL-C as BACKACC was writing to the hard disk caused a GP fault. RESOLUTION ========== The signal handler was changed so that it now correctly releases semaphores. Binary Affected --------------- BACKACC.EXE ------------------------------------------------- OS/2 Server Hangs if Network Adapter Cannot Reset ------------------------------------------------- CSD: LM22.CSD00.048 SYMPTOMS ======== COMTOKR.OS2 went into a tight loop if the network adapter was in a state where it would not reset, causing the OS/2 server to hang. RESOLUTION ========== The driver was checking an incorrect flag. Code was changed so that it now checks the correct one. Binary Affected --------------- COMTOKR.OS2 ------------------------------------------------------------ Duplicate Name and Net Address on Token Ring Crash Server ------------------------------------------------------------ CSD: LM22.CSD00.049 SYMPTOMS ======== A server would crash if it had the same NetBIOS name, local session number and locally administered net address as a workstation on the network. RESOLUTION ========== Since incorrectly administered workstations can cause problems on the network, the fix centered on detecting this situation and causing the offending workstation to hang. Binary Affected --------------- NETBEUI.EXE NETBEUI.OS2 ----------------------------------------------------- MS-DOS Applications Incorrectly Report "0 Bytes Free" ----------------------------------------------------- CSD: LM22.CSD00.050 SYMPTOMS ======== On server drive geometries exceeding 2 GB, MS-DOS applications would report that there was no free space left on the disk, or "0 bytes free." RESOLUTION ========== MS-DOS applications (such as DIR) do 16-bit multiplication to determine the free space on the server disk, and on server drive geometries exceeding 2 GB the cluster size becomes to big to be contained in a 16-bit number. Checks were installed to prevent returning more information to MS-DOS clients than can fit into a 16- bit number. Binary Affected --------------- HPFS.386 ----------------------------------------------------- RESTACC Fails with "SYS0111 File Name Too Long" Error ----------------------------------------------------- CSD: LM22.CSD00.052 SYMPTOMS ======== RESTACC failed with a "SYS0111 File Name Too Long" error under the following circumstances: - net access c:\data /a /f:all /s:write;delete;acl - net access c:\data /a /f:acl /s:write;delete - net access c:\data /a /f:acl;delete /s:write - net access c:\data /a /f:acl;delete;write /s:all followed by: backacc c: /s restacc c: /s RESOLUTION ========== The method by which the size of the structure is determined has been changed. Binary Affected --------------- NETAPI.DLL ------------------------------------------------------------ Badly Formed Server Message Block Sent to Server Causes Trap ------------------------------------------------------------ CSD: LM22.CSD00.053 SYMPTOMS ======== A badly formatted server message block sent to the server, caused the following trap: Trap 000D AX=0000 BX =0FF6 CX=0002 DX=0001 BP=EEF2 SI=D2C4 DI=9BEA DS=0658 ES=0658 FLG=2202 CS=0908 IP=174C SS=0038 SP=EEAC MSW=001B CSLIM=370B SSLIM=EB85 DSLIM=FFFF ESLIM=FFFF CSACC=9B SSACC=97 DSACC=93 ESACC=93 RESOLUTION ========== The method by which the size of the incoming server message block is determined has been made more robust. Binary Affected --------------- HPFS.386 ------------------------------------------------- Netlogon Performs Continuous Full Synchronization ------------------------------------------------- CSD: LM22.CSD00.054 SYMPTOMS ======== If a backup domain controller failed to set its password (which causes a new attempt to do so every 15 minutes) and a full sync took longer than 15 minutes, Netlogon performed a continuous full sync. RESOLUTION ========== A check was installed to make sure that a request to change the backup domain controller password is not dealt with during a user-accounts system update. Binary Affected --------------- NETLOGON.EXE ---------------------------------------------------------------- UPS Service Fails Compaq ProSignia if Low Battery Signal Enabled ---------------------------------------------------------------- CSD: LM22.CSD00.060 SYMPTOMS ======== Uninterruptible power supply (UPS) service failed when connected to the serial port of a Compaq ProSignia running Microsoft LAN Manager 2.1 or 2.1a and the low battery signal check was enabled in LANMAN.INI. The server shut down during initialization even under normal UPS operation, usually when the UPS service was started. RESOLUTION ========== Timing conditions were changed so that the UPS service does not fail with high speed machines. Binary Affected --------------- UPSDRV.OS2 UPS.EXE -------------------------------------------------------------- Windows Hangs or Crashes to MS-DOS Prompt If Running Many Apps -------------------------------------------------------------- CSD: LM22.CSD00.061 SYMPTOMS ======== On a very low memory Windows 3.1 machine, with both Windows 3.1 and Windows applications running off of a server on the net, loading many applications caused Windows to hang or to crash to an MS-DOS prompt when pulling up print dialog boxes or exiting applications. RESOLUTION ========== Two instructions that prevent page faults (which invalidate the stack) from occurring in Windows have been reversed in order so that they now function more effectively. Binary Affected --------------- NETWKSTA.500 NETWKSTA.401 NETWKSTA.330 ------------------------------------------------------------------- Workstation Hangs with NET 805, Server Records Incomplete NCB Error ------------------------------------------------------------------- CSD: LM22.CSD00.062 SYMPTOMS ======== A custom named pipes program, when performing raw block write commands, would cause the workstation to hang with a NET 805 error. The server would also record a NetBIOS "Incomplete NCB Error" message. RESOLUTION ========== Code was changed to check that the pipe was not in a closing state before performing the operation. Binary Affected --------------- NETWKSTA.SYS ---------------------------------------------------------- Trap D Occurs With HPFS386 when ATTRIB *.TXT /S is Entered ---------------------------------------------------------- CSD: LM22.CSD00.063 SYMPTOMS ======== A TRAP D would occur with HPFS386 when the user typed ATTRIB *.TXT /S at the root of a large (greater than 1 GB) partition with a huge tree structure. RESOLUTION ========== An invalid instruction has been changed. Binary Affected --------------- HPFS.386 ---------------- Trap D in TCPNB$ ---------------- SYMPTOMS ======== The following trap screen would be displayed on the server: TRAP: 000D AX=17FE BX=4B54 CX=02CA DX=0000 BP=0744 SI=0000 DI=0E18 DS=0D80 ES=0D80 FLG=2202 CS=0DF0 IP=2716 SS=1920 SP=073C MSW=001B CSLIM=9850 SSLIM=07FF DSLIM=417A ESLIM=417A CSACC=9B SSACC=93 DSACC=93 ESACC=93 ERRCD=000 ERLIM=**** ERACC=** Exception in device driver: TCPNB$ The system detected an internal processing error at location 0228:37CD RESOLUTION ========== An invalid instruction has been changed. Binary Affected --------------- NBDRV.OS2 ---------------------------------------------------------------- DOS TCP/IP Clients get Logged on Standalone Despite DC Responses ---------------------------------------------------------------- SYMPTOMS ======== Occasionally workstations using the TCP/IP protocol stack would be logged on standalone, despite getting logon responses from the domain controller. RESOLUTION ========== Buffers controlling datagrams were being exhausted and not being recycled. Binary Affected --------------- TINYRFC.EXE TCPTSR.EXE TCPDRV.OS2 ------------------------------------------------------- TCP/IP Server Won't Send Datagrams; BDCs Go Out of Sync ------------------------------------------------------- SYMPTOMS ======== Servers running the TCP/IP protocol would, after a period of time, stop sending server announcements, which would in turn cause the domain controllers to fall out of sync. RESOLUTION ========== Code that was not freeing packets has been changed. Binary Affected --------------- NBDRV.OS2 TCPDRV.OS2 ---------------------------------------------------------- BCASTADDR Parameter in PROTOCOL.INI Ignored by OS/2 TCP/IP ---------------------------------------------------------- SYMPTOMS ======== Under OS/2, TCP/IP was ignoring the BCASTADDR parameter in the PROTOCOL.INI file. RESOLUTION ========== This functionality was added. Binary Affected --------------- NBDRV.OS2 ------------------------------------------- All TCP/IP Servers on Net Trap in NBDRV.0S2 ------------------------------------------- SYMPTOMS ======== A particular packet sent on the network as a broadcast was causing servers to crash with the following register information: CSLIM=9850 IP=00E0 BP=0738 SI=0000 RESOLUTION ========== The software now checks for a null pointer. Binary Affected --------------- NBDRV.OS2 ----------------------------------- Server Crashes and Issues TRAP 0003 ----------------------------------- SYMPTOMS ======== A server crashed with the following output: TRAP: 0003 AX=0D60 BX=2242 CX=1000 DX=DEAD BP=071E SI=2242 DI=0000 DS=0D68 ES=0DA0 FLG=2246 CS=0D60 IP=017F SS=1920 SP=071E MSW=001B CSLIM=1680 SSLIM=07FF DSLIM=FECF ESLIM=36F7 CSACC=9B SSACC=93 DSACC=93 ESACC=F3 RESOLUTION ========== An invalid instruction has been changed. Binary Affected --------------- TCPDRV.OS2 --------------------------------------------------------- Sybase Server Doesn't Respond to TCP/IP "Cancel" Commands --------------------------------------------------------- SYMPTOMS ======== The Sybase SQL server did not respond to "Cancel" commands issued through the TCP/IP SQL server gateway. RESOLUTION ========== Support for the out-of-band data signal was added. Binary Affected --------------- SOCKETS.EXE SOCKETS.OS2 -------------------------------------------------------- TCP/IP MS-DOS Utilities Cannot Connect with IBM 3090 MVS -------------------------------------------------------- SYMPTOMS ======== Ftp and other TCP/IP MS-DOS DOS utilities cannot connect to IBM 3090 MVS systems RESOLUTION ========== MVS will not reply unless the PUSH bit is set on each packet, so the ForcePushBit parameter has been added to the [TCPIP] section of the PROTOCOL.INI file. It defaults to 0, but when it is set to 1 it causes the PUSH bit to be set on every outgoing packet. Binary Affected --------------- TCPTSR.EXE ----------------------------------------------------------------- Information Packets Incorrectly Reassembled After Crossing Router ----------------------------------------------------------------- SYMPTOMS ======== TCP/IP packets that were fragmented as they passed through routers were not being correctly reassembled. RESOLUTION ========== Changed the code to reassemble fragmented packets correctly. Binary Affected --------------- TCPDRV.OS2 TCPTSR.EXE ---------------------------------------------- TCP/IP Returns Wrong Error Code on Failed Call ---------------------------------------------- SYMPTOMS ======== When a server would go down for a client-server application (in this case, Schedule+), TCP/IP would cause the client application to hang. RESOLUTION ========== The NetBIOS return code was changed so that the application would recover gracefully. Binary Affected --------------- TINYRFC.EXE ---------------------------------------------- LM Server Trap D's in TCPDRV When Sent LLC XID ---------------------------------------------- SYMPTOMS ======== A server running TCP/IP was crashing with the following output screen: TRAP 000D AX=0104 BX=0000 CX=0000 DX=07F8 BP=0770 SI=085C DI=016C DS=07C0 ES=07F8 FLG=2206 CS=07B0 IP=0FF9 SS=1918 SP=0764 MSW=001B CSLIM=98E0 SSLIM=07FF DSLIM=FECF ESLIM=5DCB CSACC=9B SSACC=93 DSACC=93 ESACC=F3 ERRCD=694C ERLIM=**** ERACC=** RESOLUTION ========== Changed the code so that the packet was not accepted. Binary Affected --------------- TCPDRV.OS2 ----------------------------------------------------------------- TCP/IP Server Routes Traffic from Token Ring to Ethernet, Crashes ----------------------------------------------------------------- SYMPTOMS ======== A server running TCP/IP on token ring was crashing with a Trap D when traffic was routed between a multi-ringed token ring network and an Ethernet network. The IP register was 1629. RESOLUTION ========== Rather than continuing to re-use a buffer, a fix was installed to allocate a new buffer to ensure that space for routing information was always available. Binary Affected --------------- TCPDRV.OS2 -------------------------------------------------------------- Error 53--TCPCONNECTIONS Depleted, Connection Denied to Client -------------------------------------------------------------- SYMPTOMS ======== A server would run out of TCPCONNECTIONS and issue Error 53 to clients that attempted to connect to it. RESOLUTION ========== Timeout code was added for the TCP/IP FINWAIT-2 state. Binary Affected --------------- TCPDRV.OS2
