DC/DNS

[Laurie]

Hi.

Currently we have 2 DCs w/ AD integrated DNS. With the
sale of a portion of our company one of the DC will be
gone. We built another DC and attempted to add it as a
3rd AD integrated zone. It was not able to replicate w/
the other 2 servers. I have tried changing the new DC to
Primary w/ dynamic updates. When I look in sites and
services the 3rd DC is their w/ the other 2 automatically
added, but when I try to replicate I still get DNS lookup
error. I have gone through all the DNS troubleshooting
guides. I can ping by dns name. All A, SRV records
exist. PTR exists in reverse lookup. The 4 sub-folders
exist under the zone. I tried to remove the 3rd DC from
AD but I can not b/c it can not find another suitable DC
for the domain.

What can I do?
Thank-you.

Can you provide output from dcdiag and netdiag ? any EventLog entries would
be helpfull.

The only fail when running both dcdiag and netdiag is for
replication: DSbind failed with error 1722. The RPC
Server is unavailable.

RPC server unavailable is DNS problem, except if you don't block RPC ports
on the network. Use nslookup to verify that you can resolve server names.
ping is not enough.

nslookup returns the proper information also.
