This all sounds DNS related.

Look for the GC entries on the DNS server. Under _msdcs

try to run netdiag/fix that will repopulate entries.

Probably should start with;

dcdiag /c /e /v

dcdiag /v /test:systemlog and see if it gives you more details on the
error.

dcdiag /fix

Is the correct DNS server being used?
