There is a discrepancy with the Exchange server name in Active Directory

[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 whether the Name attribute and the cn attribute of a server (object of class msExchExchangeServer) match. If the Exchange Server Analyzer finds that these attributes differ, an error message is displayed.

Exchange uses the cn value of the server object to identify the server internally. It uses the Name value to identify the server in the Microsoft Exchange System Manager user interface.

This error can occur if an administrator changed the Name value using a tool such as Active Directory Service Interfaces (ADSI) Edit or the LDP (ldp.exe) tool. While this action does change the server name in the user interface, it creates a discrepancy that generates store and system attendant events. You must correct the value using a tool such as the ADSI Edit snap-in, the LDP tool, or any other Lightweight Directory Access Protocol (LDAP) version 3 client.


If you incorrectly modify the attributes of Active Directory objects when you use ADSI Edit, the LDP tool, or another LDAP version 3 client, you may cause serious problems. These problems may require that you reinstall Microsoft Windows Server™ 2003, Exchange Server 2003 or Exchange Server 2007 or both. Modify Active Directory object attributes at your own risk.

To correct this error

  1. Using ADSI Edit or a similar tool, locate the server object in Active Directory.

    The CN and Name attribute can be found at:

    CN=Configuration,CN=Services,CN=Microsoft Exchange,CN=Organization,CN=Administrative Groups,CN=Administrative group,CN=Servers,CN=Server
  2. For the Name attribute, type a new string value that matches the value of the CN attribute.
