[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 queries the Microsoft Windows® Management Instrumentation (WMI) class to determine the value for the ServicePackMajorVersion key. The Exchange Server Analyzer also examines the following registry entry to determine the version of Windows that is running on the destination computer:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\CurrentVersion

If the Exchange Server Analyzer determines that the target system is running a Windows 2000 Server operating system but is not running the Update Rollup for Windows 2000 Server Service Pack 4, a warning is displayed.

As a best practice, it is recommended that you install the latest service packs and rollups for all software in the Exchange deployment.

To correct this warning

  1. Update all domain controllers and global catalog servers that are running Windows 2000 Server to the Update Rollup for Service Pack 4, plus the latest hotfixes and updates from Windows Update.

  2. Update all Exchange Server computers to the latest rollup and update rollup.
