[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 the version of the Microsoft Windows® operating system running on the Exchange Server computer:

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

A CurrentVersion value of 4.0 indicates the computer is running Microsoft Windows NT® Server 4.0. A value of 5.0 indicates the computer is running Windows 2000 Server, and a value of 5.2 indicates the computer is running Windows Server™ 2003.

If the Exchange Server Analyzer finds the value for CurrentVersion equal to 4.0, a warning is displayed.

This warning indicates that this Exchange Server computer is running Windows NT Server 4.0. Windows NT Server 4.0 does not provide as much diagnostic information as later versions of Windows Server. As a result, the Exchange Server Analyzer will only be able to gather and analyze a limited amount of information.

  1. There is no immediate action to be taken. This warning is for informational purposes.

  2. Because Windows NT Server 4.0 and Exchange Server version 5.5 are reaching the end of their product lifecycle, you should consider upgrading to Windows Server 2003 and Exchange Server 2003.

For more information about the product lifecycle for Windows NT Server 4.0 and Exchange Server 5.5, see the Microsoft Support Lifecycle Web site (http://go.microsoft.com/fwlink/?LinkId=21759).

For more information about Windows Server 2003, see the product home page, "Microsoft Windows Server 2003" (http://go.microsoft.com/fwlink/?LinkId=26095).

For more information about Exchange Server 2003, see the product home page, "Microsoft Exchange Server 2003" (http://go.microsoft.com/fwlink/?LinkId=21573).
