We have been having some serious issues with our Primary Domain Controller (Win 2k3). I believe I have found the root of the issue, but am unsure how to resolve it. For some reason, my PDC is not adding a DNS suffix to itself. This holds true when I try to change the Operations Master in AD Domains and Trusts, try to connect to a Domain Controller using AD Domains and Trusts, or even when it registers itself in DNS on it's own server. This what I'm getting for the PDC:
Every other DC looks like this:
I tend to believe this is causing all of my permissions errors for AD on the domain. I have run dcdiag /fix and netdiag /fix, and get the same failure everytime. The big hangup I'm having currently is my PDC is returning:
"*** Warning: could not confirm the identity of this server in the directory versus the names returned by DNS servers. If there are problems accessing this directory server then you may need to check that this server is correctly registered with DNS
Please help me get going in the proper direction.
