Internal Tracing for 32-bit CPI-C Applications Not Available

• Microsoft SNA Server version 3.0

SYMPTOMS

Internal tracing of 32-bit CPI-C applications is not available when running the CPI-C application on an SNA Server, SNA Workstation, or Windows NT SNA Server client.

NOTE: Internal traces for SNA Server components are typically run at the request of Microsoft Technical Support.

CAUSE

The SNA Server has always had SNADMOD internal tracing for SNA Applications that use any of the SNA Server's supported APIs. These internal traces are used to diagnose problem between the client-server interface. SNA Server hasn't supported internal tracing within the CPI-C DLL itself, which would allow the diagnosis of logic-related problems within the handling of the CPI-C API.

RESOLUTION

The 32-bit CPI-C libraries for SNA Server 3.0 have been updated to include support for internal tracing within the CPI-C DLL.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
