Active Directory and DNS problem

August 22, 2008 at 04:38:50
Specs: Windows 2000 Server, Pentium 4 3.2Ghz/1gb
My active directory keeps dropping its connection to DNS. As long as I keep AD open, it works fine. However, if I close it, and don't use it for some hours, it will not load up due to a dns problem. Also, when I use the NSLOOKUP command, I get the message, "Can't find server name for address 192.168.0.x: Non-existent domain."

When I reboot, it clears up.

DNS and AD have previously been working fine, for some years - so this just started happening in the last few weeks.

DNS and AD work fine on my backup DNS/WINS server.

Appreciate any help or suggestions!

That is strange since DNS on both servers should be the same. NSlookup would appear to say they are not the same.

Is dns setup as primary/secondary or Ad intergrated?

What does the dns event log say concerning errors?

Hi Wanderer,

The dns is setup as primary/secondary (but the load zone data on startup is from AD and the registry).

No errors in the dns event log.

Thanks for your quick response and help!

Primary/secondary do not store or retrieve dns information from AD. Why do you think it does? Did you make changes in AD concerning DNS?

1)My DNS server was unable to open Active Directory.In DNS Event it gives "Error- id 4000" and "Warning- id 4013"

2)When I try to join any computer in my domain with domain administrator it gives the following error:
"Login Failure: the target account name is incorrect"

3)My Active Directory & DNS is in the same server. I had problem with my DNS. so I tried to reinstall it, but I cannot connect my DNS with Active Directory or create partition and it shows "Active Directory domain (null)" in "Active Directory Zone Replication Scope"

Need any help or suggestions!
