[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

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

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\RpcEtwTracing

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.
