The Key Distribution Center (KDC) raised an error for which Microsoft Operations Manager (MOM) did not have a specific rule. Refer to the event log message for details.
The most likely cause is that the domain controller has been upgraded with a service pack, hotfix, or operating system upgrade and the Active Directory Management Pack has not been upgraded.
To upgrade to the latest version of the Active Directory Management Pack, see the Management Pack Catalog at http://go.microsoft.com/fwlink/?LinkId=82131.
