I have a Windows 2000 workstation connected to a Netware 3.2 server (which is really 3.12 with Y2K patches). It was setup originally running on Client32 v4.81 with the latest patch. It ran fine for about a month. Mapping drives during login started to fail intermittently. When it is experiencing a problem, it logs the user in (I see the user name on the server’s Monitor screen) and after a couple of minutes fails during the mapping. When it’s working fine, there is no delay and drives are mapped immediately. I upgraded Client32 to v4.83 with the latest patch. No luck. I have checked the cable, switched to another hub port, replaced the workstation NIC, set the NIC to 10Base-T, half duplex (no autodetect), set the frame type to 802.2 (since that’s the only frame type the server is running), set Client32 to use Bindery first instead of NDS, reapplied Win2K service pack 2, and ran bindfix twice. I can login that user from a Win9x PC with no problems. The workstation is connected to an APC UPS. The Win2K event viewer shows an event ID# 12291 (SAM failed to start the TCP/IP or SPX/IPX listening thread). I couldn’t find anything in Microsoft’s knowledgebase that helped. Any insight would be greatly appreciated. We see no pattern to the frequency of the problem.
