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 Exception number: c0000005 (access violation) .  .[Data omitted] .
