Server name mismatch
[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. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the setting for the This Server value:
The Exchange Server Analyzer also queries the Active Directory® directory service to determine the value of the name attribute for each Exchange server object.
Finally, the Exchange Server Analyzer queries the Win32_Service Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the Started key for the Cluster service (ClusSvc). A value of TRUE indicates the Cluster service is started and a value of FALSE indicates the Cluster service is not running.
If the Exchange Server Analyzer finds that the value for the This Server key does not match the value for the server object's name attribute in Active Directory for any Exchange Server computer that is not running in a server cluster, an error is displayed.
To correct this error, you must edit the This Server registry key to match the value of the name attribute in Active Directory.
This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore the registry if a problem occurs. For information about how to restore the registry, view the "Restore the Registry" Help topic in Regedit.exe or Regedt32.exe.
To correct this error
Open a registry editor, such as Regedit.exe or Regedt32.exe.
Navigate to: HKLM\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem.
In the right pane, double-click This Server, enter the correct name for this computer, and then click OK.
Close the registry editor and restart the Exchange Server computer for the change to take effect.
Before you edit the registry, and for information about how to edit the registry, see the Microsoft Knowledge Base article 256986, "Description of the Microsoft Windows Registry" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=256986).
