Yes I got it. Thanks! 1 Last question... Since the ISA Server is in the topic. The setup in my mind would be the ff.
1.) On DC's TCP/IP Settings the DNS Server would be the DC's IP not the 127.0.0.1. The secondary would be left blank.
2.) I would setup the DC's DNS Server to forward to the ISA Server's DNS Server so that all internet related dns requests would be forwarded to ISA's DNS server which will also forward to my ISP's DNS server.
All correct? Do we have some considerations to make?

You are correct in point 1, but I would use the server's own IP address instead of 127.0.0.1 in point 2.
When a client PC makes a DNS request, it sends that request to its primary DNS server. If the primary DNS server is not available, the PC will send the request to its secondary DNS server. The DNS server will look in its own table for the resolution requested. If that resolution is not found, the DNS server forwards the request to the next up-level DNS server. That next up-level DNS server will be your ISP's DNS server IF you configured your DNS server to forward to the ISP's DNS server. If you did not configure your DNS server to forward to your ISP's DNS server, your DNS server will use a built-in list of up-level DNS servers to forward the request.
Your DNS server can reside on your DC or on an ISA server (or on a member server). The DNS service is an add-on service, so it doesn't matter what other services are running on the hardware (performance issues being ignored for this statement).
If you want a better understanding of how your DNS server works, check out the back issues of Mark Minasi's newsletter at http://www.minasi.com. Mark gives great information about DNS and how to set it up to work in different environments.

So does this mean the following: 1.) I will point my DC's gateway to the router. 2.) On the TCP/IP of my DC's NIC I will only put 127.0.0.1 on the DNS Server and leave the 2nd one blank.
Presuming this is correct, I just have a curious question. Will the DC be intelligent enough to forward the internet DNS request to
the up-level DNS Servers (My ISP's DNS server)?
Here's my 2nd alternative.
I setup an ISA Server with a DNS Server as my router/gateway. Now that all of my client computers gateway and dns point to the ISA Server. How can the ISA Server forward DC related DNS queries by client computers to the DC itself?
