SYMPTOMS
Windows NT supports applications running under different user contexts.
However, if these applications attempt to use the SNA Server API interfaces
on a Windows NT computer running the SNA Server Windows 95 client, only the
first SNA application will work. The error message will vary, depending on
the application, though an APPC or CPIC application will encounter the
following API return codes:
APPC primary return code = 0xF004 (AP_COMM_SUBSYSTEM_NOT_LOADED)
CPIC return code = 20 (PRODUCT_SPECIFIC_ERROR)
NOTE: The above errors may occur under other more common circumstances as
well, though these errors should not be confused with the specific problem
described in this article. For more information about the above API errors,
see the following Knowledge Base articles:
148359 SNA Server APPC Error: F004 AP_COMM_SUBSYSTEM_NOT_LOADED
132720 SNA Server CPIC Allocate Error 20 (CM_PRODUCT_SPECIFIC_ERROR)
CAUSE
The SNA Server Windows 95 client was originally designed to support client
applications under a single user context.
WORKAROUND
Use the SNA Server Windows NT client software on the Windows NT computer,
instead of the SNA Server Windows 95 client software.
STATUS
Microsoft has confirmed this to be a problem in the SNA Server Windows 95
client included in SNA Server versions 3.0, 3.0 Service Pack 1, and 3.0
Service Pack 2.
This problem was corrected in the latest SNA Server version 3.0 U.S.
Service Pack. For information on obtaining this Service Pack, query on
