Sounds like maybe the workstations are also pointing to the dns server.
Make sure about this:
1) point all workstations/servers dns to your internal dns *only. Remove
any isp or other dns server ip.
2) Make your internal dns forward to your firewall (if it has this or you
want this) or to your isp. You can also use root-hints.

Now if you turn off your firewall, the only thing that should stop is the
inet acccess (all local stuff should work.)
 
Here's a question...I think i just have something misconfigured.

We have a WINS Server and 2 DNS servers internally, they both are set to
forward DNS requests to external hosts when they cannot resolve them.
However, when I make a config change to our firewall, it requires a restart,
during that time, workstations cannot resolve internal names to IP.

What do i have configured wrong? is it on the server or the workstation?
 
WOW. Strangest thing I've ever heard. When you unplug the firewall
completely (meanning no Internet access whatsoever), can the internal
clients resolve internal addresses?

Do you have a single label name AD DNS domain? I believe that *may* cause
this behavior.

Your AD DNS domain name is a single label name, such as "domain" instead of
the required "domain.com" format.

Curious of my previous question about unplugging the router completey.
