DOCUMENT:Q142941 13-JUN-2001 [sna] TITLE :Clients Using Novell ODI IPX/SPX Protocol Are Disconnected PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:2.0,2.1,2.11,3.0 (all SP),4.0,4.0 SP1,4.0 SP2,4.0 SP3 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 2.0, 2.1, 2.11, 3.0 SP1, 3.0 SP2, 3.0 SP3, 3.0 SP4, 4.0, 4.0 SP1, 4.0 SP2, 4.0 SP3, on platform(s): - the operating system: Microsoft Windows NT ------------------------------------------------------------------------------- SYMPTOMS ======== MS-DOS-based and Microsoft Windows-based computers using Novell's IPX/SPX protocol to access an AS/400 through Microsoft SNA Server are disconnected after a brief period of inactivity. If the client is using a 5250 emulator to communicate with an AS/400, the following errors appear: Event 38: APPC session deactivated abnormally, qualifier 0005 Event 92: APPC TP detected abend of SNA subsystem If your client computer is using a 3270 emulator to communicate with a host, you lose your 3270 session and be reset to the initial host signon screen upon reconnecting. The failure in the API trace shows: SEND_DATA response, result = COMM_SUBSYSTEM_ABENDED and Events 38 and 92 are logged in the Application Log (as shown in the Event Viewer). CAUSE ===== The IPX/SPX protocol is allowing a timeout to expire, after which the SNA Server client loses it's IPX/SPX session to the SNA Server, causing SNA Server to reset the user's host or AS/400 session. RESOLUTION ========== Download the latest version of IPXODI.COM from Novell, dated 8/8/95 or later and replace the original file on the client workstation. The following information should be added to the NET.CFG file (after the DOS Requestor line): "Protocol IPXODI SPX Verify Timeout 65000 SPX Abort Timeout 65000" (without the quotation marks) Additional query words: prodsna ====================================================================== Keywords : kbnetwork Technology : kbAudDeveloper kbSNAServSearch Version : WINDOWS:2.0,2.1,2.11,3.0 (all SP),4.0,4.0 SP1,4.0 SP2,4.0 SP3 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
