MTA Computer name mismatch
Topic Last Modified: 2005-11-18
The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the setting for the message transfer agent (MTA) Computer value: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
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 MTA Computer 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 Windows Server cluster, an error is displayed.
To correct this error, you must edit the MTA Computer registry key to match the value of the name attribute in Active Directory.
