It starts as a programming problem:
Domain.GetCurrentDomain().DomainControllers
triggers an exception:
Unable to obtain DNS hostname of Active Directory domain controller with ntdsa object name "CN=NTDS Settings,CN=SERVER002,CN=Servers,CN=Site01,CN=Sites,CN=Configuration,DC=TLD,DC=org".
Because ONE domain controller has a problem, no domain controllers are returned.
This then becomes a DNS problem, I believe.
What entry, anywhere can I modify (manually if needed) to be able to get the value into DNS, correctly?
Thanks.
