Call tracing is disabled
[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 entry to determine whether Call Trace logging is enabled:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem\Disable Call Tracing
If the Exchange Server Analyzer finds that the registry value for Disable Call Tracing is present and configured to use a value of 1, and the computer is running Exchange Server 2003, the Exchange Server Analyzer displays a non-default configuration message.
When Call Trace logging is enabled, function call data for the Store.exe processes is logged. By default, call tracing is enabled on computers that are running Exchange Server 2003. Note that this function is disabled by default on Exchange 2000 Server. However, if you are running Exchange Server 2003, you should enable call tracing unless you have been instructed otherwise under the guidance of Microsoft Product Support Services. If call tracing is enabled, it collects important information that you can use for troubleshooting any issues that occur with the store process.
