Event ID 1054 Windows cannot obtain the domain controller name for your computer network.....
Event ID 13508 The file replication Service is having trouble enabling replication from <old DC> to <new Dc>......
Event ID 27 While processing a TGS request for the target server krbtgt/xyz.lan, the account.....did not have a suitable key for generating a Kerberos ticket.....

Thank you Rich for your response.
The error is appearing on all the Servers (PDC & Member Servers). There was an old DC, however it is removed long time back.

If you open DNS Manager, and look at the properties if the individual forward lookup zones... are they Active Directory Integrated, Primary, or Secondary zones?

They are Active Directory Integrated

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Because you've specified some DNS servers as member servers, I assume you are not using AD Integrated zones. I assume there is one server that is the primary for the zone which includes your active directory objects. I assume that's the server on which you have the error concerning not being able to load a zone. Added to the reference to "<old DC>", I have this fear that it may be possible that the machine which had been the primary on the zone has been demoted/retired. If the zone one which active directory relies has failed to load on the primary, and everything is counting on the primary (all the secondaries have expired references)... then all the error messages would be a symptoms of the same cause.
Unfortunately, I've had to assume a lot. (And because so much needs to be assumed, I also assume that's why the question is currently neglected. :-) It's hard to guess what might be occurring here.)
To proceed... confirm which assumptions you can. On which server was that first (failed to load) error? Where there any other recent problems with that server? Was the old DC retired 'recently'?
