SUMMARY
You may need to enable additional Microsoft Windows NT Performance Monitor information store logging for troubleshooting purposes.



MORE INFORMATION
To enable additional Performance Monitor information store logging, you need to edit the registry:

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

 Start Registry Editor (Regedt32.exe). Locate the Library value under the following key in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\Performance

 On the Edit menu, click String, change the value from c:\exchsrvr\bin\mdbperf.dll to c:\exchsrvr\bin\mdbperfX.dll, and then click OK. Quit Registry Editor.

After you modify this registry value, you must restart Performance Monitor to see the new counters. The new counters are located under the MSExchangeIS object.
