I am getting an error in Windows Server 2003 "DCOM was unable to communicate with the computer "xyz" using any of the configured protocols. I would like to correct the error but I am not sure how. The computer in question was an old domain controller that crashed and is no longer part of the domain. How can I remove any reference to this old DC?

Thank you,

Will need to do a metadata cleanup on Active Directory to remove this old DC. Can you post the exact error you are recieving.

I just followed the procedures for the metadata cleanup and the server listed in the error message is not showing up for me to remove during the cleanup process. I have also look at DNS and cannot find any reference to the server. Any other suggestions?

Thank you,

Look over this but if the computer name is the old DC then you need to do a metadata cleanup and clean DNS of the records for this DC.
