The DNS Server was unable to complete directory service enumeration of zone budbeach.local. This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and repeat enumeration of the zone. The extended error debug information (which may be empty) is "". The event data contains the error.

Please also note that (if I did it correctly) I installed certificate services recently on both servers when I had the same problem and added the domain controller option and allowed for client authentication. Then I removed the bad certificates..

Alot of these problems seemed to happen after installing McAfee total endpoint protection about 3 months ago but has recently gotten worse, but not sure if it has anything to do with it.

I know its a lot of info but Im sure they are probably all related somehow.
Please help!
