The transport and routing components in Microsoft Exchange Server 5.5 have been significantly modified in Exchange 2000 Server, and as a result, many transport and routing problems have become quite difficult to solve. To assist Microsoft Product Support Services (PSS) in troubleshooting and resolving Exchange 2000 Server transport and routing problems, Microsoft has provided a utility called "Regtrace" with the Exchange 2000 Server CD.
This article describes how to configure Regtrace to capture detailed information about the transport and routing components in Exchange 2000 Server. This article also explains what to do with that information.
Enabling RegtraceRegtrace.exe can be found on the Exchange 2000 Server CD in the Support\Utils\I386 folder. Copy Regtrace.exe to a folder on the server, and then run the program.
To activate the Tracing feature on the server where Exchange 2000 is installed:
What to Do with the LogsThe trace file will be available at the location that you specified on the Output tab of Trace Settings window in step 3. The default location for the file is C:\Trace.atf.
The trace file is a binary encoded file that needs to be "fixed" before it can be viewed. The trace file contains an enormous amount of debug-level information about all of the transport and routing components that are being traced. For this reason, PSS requires customers to send in the trace files for internal analysis. The files may need to be zipped and delivered to PSS by means of an FTP server, Microsoft File Exchange (MSFE), or Premier Service Desk. For details on any of these delivery methods, consult your PSS representative.
