RESOLUTION ========== To configure for multiple sessions, change your NET.CFG file as follows to increase sessions and reduce the number of read buffers that SNA Client uses. NOTE: The following information is base on a Windows 3.1 computer using Novell's VLM's and Netsoft's Midrange Bundle. These changes allowed an increase in the number of sessions that could be run at one time from 5 to 15 on the client. In the [WNAP] section of the WIN.INI file add the following line: "SPXReadBuffers = 2" (without the quotation marks) In NET.CFG file, add the following: "Protocol Stack IPX IPX Sockets = 40 SPX Connections = 50" (without the quotation marks) Additional query words: prodsna ipx spx ====================================================================== Keywords : kbnetwork sna4 kbsna400sp1 kbsna400sp2 Technology : kbAudDeveloper kbSNAServSearch kbSNAServ300 kbSNAServ211 kbSNAServ400 kbSNAServ400SP1 kbSNAServ400SP2 Version : WINDOWS:2.11,3.0,4.0,4.0 SP1,4.0 SP2 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
