There is no way to "search" for it, other than going into each PC/Server and running:
ipconfig /all from the command prompt (go to Start -> Run -> cmd, then press Enter). When you run this command you can see what DNS server(s) the PC/Server is associated with. If you don't have a DHCP server configured with DNS to disperse to your clients, then it's pretty much a manual process.

If you're using DHCP, make sure the scope isn't configured with the old DNS address.
Are you receiving the message on both DC and desktops?

That's pretty much the only place UNLESS you have statically assigned IPs/DNS settings. There is no 'search' method for that; you will have to run IPCONFIG /ALL on servers/PCs, or just check the network adapter's IP settings manually.

In re-reading over your orig post, you mention you're getting 'a page saying you need to change it', what page and what is the specific msg you're receiving. Please, when posting on EE, provide as much information as possible so as to provide the best possible solutions for you. :)

Thank you for posting that msg. So, did configuring your DMZ DNS server resolve this for you?
