yesterday I notice an issue on my primary DNS server as follows:
I went to the dns server under the forward lookup zones on _msdcs.mydomain.local properties ---> name servers -----> edit on my primary dns server ------> trying to resolve its name but it shows this message .... "a timeout occurred during validation"
tried to do the same steps on my additional DC on its DNS server everything works fine.... and I don't have any problem resolving the workstations on my network
but when I do nslookup on the primary DC it shows this message if the primary DNS server set to it self
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
