DNS Problems Event ID 4004

[Rozzer]

Hello All,

 

Been having this on going problem with our DNS. We keep getting event ID 4004

 

The DNS server was unable to complete directory service enumeration of zone (SERVERNAME). 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.

 

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

 

Our contractors have been "trying" to fix it but not getting anywhere. Bit clueless to be honnest. Anyone had or know how to fix this error?

 

Thanks in advance.

Are you getting 4015 errors as well?

 

Check your pointers.

 

Edit: Sorry - just read the clueless bit.

 

Make sure that you have a pointer that lists your DNS server in the Reverse Lookup Zone or if you haven't got any zones set one up (or more depeding on your setup) and create a pointer to the DNS server.

To futher what HBJB said, you should have a forward lookup and a reverse lookup for each machine.

 

e.g.:

 

ping -a 192.168.8.1

should return not only the ping requests to any machine but also the DNS name of the machine too.

 

ping MyServer

will obviously resolve Name to IP, reverse lookup resolves IP to name.

 

If you have absolutely NOTHING in your reverse lookup, make a zone (or few) for the IP ranges you have under reverse lookup in your DNS.

 

In your FORWARD lookup you have A records, in your reverse lookup you have PTR records. All should automatically add themselves over time, except for the DNS server itself, which you'll have to manually create.

 

If clients don't automatically add themselves and you're using DHCP go check the DHCP settings too.

 

For some reason adding reverse lookup to our DNS made those errors disappear.

Hope that helps!

 

Now how much were those contractors being paid??

Also remember to enable Aging otherwise you'll end up with old bogus records (epsecially in your reverse zone).
