To determine whether debug tracing is enabled, the Microsoft Exchange Server Analyzer Tool uses the command processor to run the following command:

logman query exchangeDebugTraces -s ServerName -ets

If the command executes successfully, debug tracing is enabled.

If debug tracing is enabled, the Exchange Analyzer displays a warning message. Debug tracing should only be enabled when you want to troubleshoot an issue. If debug tracing is allowed to run for a long time, hard disk space may fill up and the performance of the computer may be affected.

To address this warning, disable debug tracing on the target computer.

The logman tool cannot be run from a Windows Server 2003-based computer to query a Windows Server 2008-based computer. If this occurs, you receive the following error message:


Invalid class."

You must run the Microsoft Exchange Analyzer Tool from a Windows Server 2008-based computer to determine whether debug tracing is enabled on a Windows Server 2008-based computer.
To disable debug tracing
  1. Start the Exchange Management Shell.

  2. Type ExTra, and then press ENTER.

  3. Click Go to Welcome screen.

  4. Click Select a task.

  5. Click Trace Control in the Related Functions area on the Troubleshooting Task Selection Screen page.

  6. On the Trace Control page, click Stop tracing now, and then click Exit.

  7. Close Microsoft Exchange Troubleshooting Assistant, and then close the Exchange Management Shell.
