The Microsoft® Exchange Server Analyzer Tool reads the following registry key to determine the value data:


If the Exchange Server Analyzer finds that the value data for the RpcEtwTracing registry key is set to 1, the Exchange Server Analyzer displays a non-default configuration message.

You use the value data for the RpcEtwTracing registry key only to troubleshoot network problems between Microsoft Office Outlook® 2003 and Exchange Server. It is recommended that you disable the RpcEtwTracing registry key if you are not currently troubleshooting a problem.

The Exchange Server Analyzer reports this configuration for informational purposes only. No action is required. However, you can delete the RpcEtwTracing registry key if you want to restore the default configuration.

This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore the registry if a problem occurs. For information about how to restore the registry, view the "Restore the Registry" Help topic in Regedit.exe or Regedt32.exe.

  3. Delete the RpcEtwTracing value.
