The information in this article applies to:

  • Microsoft SNA Server 4.0
  • Microsoft SNA Server 4.0 SP1
  • Microsoft SNA Server 4.0 SP2
  • Microsoft SNA Server 4.0 SP3
  • Microsoft SNA Server 4.0 SP4
  • Microsoft Host Integration Server 2000

SYMPTOMS

If a blank string (one or more spaces) is displayed in the Locate servers by Server Name box in the SNA Server client or Host Integration Server (HIS) 2000 End-User client for Microsoft Windows 95 or Microsoft Windows 98, the next time that you view the client configuration, no servers are listed. When you access a host session, you may receive a message indicating that no SNA Servers or Host Integration Servers can be found in the subdomain.

NOTE: This issue is not seen with SNA Server for Microsoft Windows NT or the HIS 2000 Admin client.

In some cases, when the SNABase service is stopped and restarted, a Drwtsn32.log file is generated if Drwtsn32.exe is configured as the default debugger. When this occurs, the Drwtsn32.log file will look similar to the following:
   Application exception occurred:
           App: exe\snabase.dbg (pid=209)
           When: 7/25/2000 @ 14:12:10.423
