Unable to join domain, receive domain controller not found error

By ahourigan ·
I recently had some problems with my internet upgrade and had to change the DNS entries on my DNS servers ( which are 2 seperate machines running win server 2003).
since then, i have not been able to add any xp pro machine to the domain, i receive an error. I have one server as the domain controller and 2 other machines serving as DNS servers. Is there something that i need to update on my domain controller when i changed the DNS entries on the DNS servers? Anyone else experience something similiar?

I changed the DNS IP entries, AT&T made an upgrade and i was having internet issues, as a result i had to change the DNS IP's. Since i made that change on the DNS servers, i have not been able to add a machine to the domain. I am able to ping everything on the network prior to the change.

The DNS IPs that you changed, I'm assuming were the forwarding IPs to AT&T's DNS IPs? Have your internal IPs and FQDNs of your DNSs changed at all?

What is the exact error message that you are getting from the client machines?

I would start by double-checking your DNS settings and making sure those IPs are accurate, and that there weren't any other changes that were made as a result.

Yes, they are fowarding to AT&T's IP's and no the IP's internally did not change. We are on Legacy Static, not PPoE. Im almost certain it has something to do with the DNS change that i made, but i cant pinpoint where the problem lies.
Here is the exact error...
