This Exchange Server 2003 server is not running the final Service Pack 2 build

[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 Active Directory® directory service to determine the value of the serialNumber attribute for all Exchange Server objects in the directory. The serialNumber attribute is a string value that includes both the version of Exchange Server and the version of the service pack, if installed. For example, on an Exchange Server 2003 computer that has Service Pack 1 installed, the serialNumber attribute is equal to Version 6.5 (Build 7638: Service Pack 2).

If the Exchange Server Analyzer finds the value for the serialNumber attribute contains 6.5 and Service Pack 2 in its string, but does not contain 7638 in the string, the Exchange Server Analyzer displays a warning.

This warning indicates that the Exchange Server 2003 computer is running a pre-release version of Exchange Server 2003 Service Pack 2.

Because Exchange Server service packs cannot be uninstalled, it is strongly recommended that you do a full backup of the computer running Exchange Server before applying any service packs.
To correct this warning
  1. Obtain the final version of Exchange Server 2003 Service Pack 2 at the Exchange Server 2003 Service Pack 2 Web site (

  2. Review the Exchange Server 2003 Service Pack 2 Release Notes (

  3. Completely back up the Exchange Server computer.

  4. Apply Service Pack 2 for Exchange Server 2003.

  5. Take another complete backup of the computer running Exchange Server.
