I acquired a poorly config network.It has a w2k DC w/ DNS DHCP.also has w2k3 DC but many errors. DNS errors eID 4004 “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.”
There are also replication errors between the two DCs. If w2k is down, no DNS works. if w2k3 is down, all is fine, so w2k3 isnt functioning correctly. how to fix DNS and replication
