The Microsoft® Exchange Server Analyzer Tool queries the Win32_OperatingSystem Microsoft Windows® Management Instrumentation (WMI) class to determine the value for the Version key on Active Directory Connector (ADC) servers in your Exchange organization. The Exchange Server Analyzer also examines the following registry entry to determine the version of Windows that is running on the ADC servers:

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

If the Exchange Server Analyzer finds the value for the second instance of CurrentVersion to be 5.2, and the value of Version does not equal 5.2.3790, an error is displayed.

A CurrentVersion value of 5.2 indicates the computer is running a Windows Server 2003 operating system. The Version value for the released version of all Windows Server 2003 operating systems is 5.2.3790. Any other value for the Version key indicates that a pre-release version of Windows Server 2003 is in use.

Unless you are part of a Technology Adoption Program (TAP) or similar Microsoft-sponsored program, Microsoft does not support or recommend the use of pre-release software in production environments.

To correct this error

Upgrade all Exchange infrastructure servers, including domain controllers, global catalog servers, ADC servers, and Exchange Server computers to the latest released software.
