KDC 11 Error in the System Event Log

Filed Under (Active Directory, Windows Server 2003) by on 07-11-2008

I ran into this error awhile back after building a new root level Domain Controller (DC). My initial health checks panned out ok but after about an hour the following should up in my System Event log:
Event Type:    Error
Event Source:    KDC
Event Category:    None
Event ID:    11
User:        N/A
Computer:    DCShortName
There are multiple accounts with name cifs/DCShortName of type DS_SERVICE_PRINCIPAL_NAME.

My forest root domain has a fairly small amount of accounts with the majority of them being DCs.  I knew that the name that was added was not in conflict with the forest root.  With this name being the shortname of the DC I knew that I would have to check other child domains.  After a quick search of the directory (GC) via Active Directory Users and Computers I was able to find another computer with the same name.  Unfortunately one of the computers had to go bye-bye…and it sure wasn’t going to be my DC.  Needless to say after the computer was removed from Active Directory the errors stopped showing up.
