Cannot contact other DNS Server

[Guest]

We have 9 windows 2003 domain servers in a forest and each DC has DNS. When I
try to open DNSmgmt, the DNS server opens locally. If I want to connect to
other DNS server in the domain, Cannot contact the DNS server. NSlookup works
fine. Why is it that I cannot connect to remote DNS server.

Hello Zareer,

There was a Vulnerability some month ago for DNS KB 935966, maybe you or
some other admin has configured the registry entry for shorttime solution,
described in this article?

Zareer,

In addition to MyWeb's question, exactly how are you trying to connect in
the console? Are you using IP address of the other DNS server, it;s FQDN or
it;s NetBIOS name?

Are the other DCs on the same subnet or are they spread across remote sites?

My initial thought is you are trying to connect via NetBIOS name and the DCs
are across remote sites and you are not using WINS. But then again, I may be
wrong. Looking forward to your response.

I tried to connect other DNS server by Server name. I also tried by IP
address, and finally I tried by FQDN which is server name.domain.com
All three different ways gives the same result. cannot contact other DNS
servers. I tried to add a host entry on one dns server and I am able to see
the change on all 9 DNS servers which tells me dns is working.

If you cannot connect by using the IP and FQDN resolves to an IP, then it
comes to either an authentication issue, DNS is not working on that machine,
or there are ports being blocked between locations possibly blocking RPC
(135). If that is the case, I would also assume other important ports are
being blocked and you may be having replication errors on the DCs.

Use portqry from Microsoft to determine if all ports are open between
locations.

I'm glad you figured out and fixed the issue.

MyWeb was on the right track for this solution.
