The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is “”. The event data contains the error.
The DNS server was unable to complete directory service enumeration of zone .. 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.
If the 4004 and 4015 events only appear at start up, you get these events because your zones are stored in AD and you only have one Domain Controller. AD cannot start with DNS, and when DNS starts, because AD has not started, DNS cannot load the zones in AD. The error goes away if you have two or more DCs with DNS installed, or if you use standard primary zones.
Add a second domain controller or Ignore the error.
