DNS Configuration

We are running a mixed NT/2000 network with 2 NT server and 2 Win 2K servers. One of the NT servers is set up as a DNS server and is connected to the Internet via dedicated dial-up. This server is a member server on our internal domain, and is also running Exchange 5.5. The internal Domain name and our INternet domain are the same, but our site is hosted by our ISP.

Our primary Win2000 server, which is supposed to be a secondary server, keeps getting an error message that it is receiving packets to itself. Can’t figure this out, and am banging my head against the wall while I run in cirles.

Does anybody have an idea about where I can find a good sample DNS configuration for NT? I would really appreciate a real world example/sample.
