Snatrace Won't Start if "Background Thread" = "Below normal"

ID: Q195987

The information in this article applies to:

Microsoft SNA Server, versions 3.0 Service Pack 1, 3.0 Service Pack 2, 4.0, 4.0 Service Pack 1

SYMPTOMS

The SNA Server trace tool (Snatrace.exe) allows you to configure the "Background Thread Priority," by selecting the "Tracing Global Properties" tab.

If the priority is set to "Below normal," it won't be possible to start the trace tool anymore.

CAUSE

This is due to an error in the code which treated the value for "Below normal" (0xffffffff) as an error when reading it from the registry. That error is preventing Snatrace.exe to display the trace property pages.

RESOLUTION

SNA Server 3.0

To resolve this problem, obtain the latest service pack for SNA Server version 3.0. For additional information, please see the following article in the Microsoft Knowledge Base:
