DNS Question

I have a 2000 Server Domain Controller and a 2000 Professional client with static IPs. The server is also the DNS server. These computers are on a LAN that connects to a firewall, then router, then a T1 line to an ISP. My domain is called COMPANY.LOCAL.

I'm wondering what DNS IP addresses do I need to put on the server and client pc to enable both to function correctly on the local LAN and the Internet?

(Note: I currently have the server's IP and DNS address the same. On the client PC, I have the server's IP address as Primary DNS and the ISPs address as Secondary DNS.)

The server  and client should both  have Local and ISP DNS IP's listed.
The order depends on how your Zone is set up and what kind of DNS caching/resolving you are set up for.
If your local DNS server can resolve everything, then it should be first. If it is only resolving for your local network, then it should be second.
Are you having specific problems ?
I hope this helps.

I am kind of new to DNS. I just want to get some more information about it. I do have a couple more questions before I close this topic out and give the points.

I used the default setup configuration for DNS when I ran DCPROMO. The server is able to resolve the local and internet addresses. I have the client PC DNS set up with the server as the Primary DNS and the ISP set up as the Secondary DNS. The client can access the Internet whether the server is on or off.

1. I am wondering, do you recommend that I set up anything in the DNS console for forward or reverse look-up zones? My LAN has only a few 2000 PCs connected to a 2000 server.

2. If the server resolves the local PCs for my LAN and internet, are there in precautions that I need to take as far as network traffic.

Thanks

The question is dependent on two things.
1) Is there any reason that an external person/program would need to know the address of a machine on your network ?

2) Do you have a firewall. ?

3) Do you plan to add to the network in the near future.

Ideally, you should set up a DHCP server and WINS on your PDC, but if do not plan to expand your LAN, then simply manually add the Static IP addresses into your DNS database.

If no one needs access to your internal machines, then you do not need the extra DNS stuff.

First rule of Net  Admin. If it works, learn why , and then don't touch it !!

The gateway is the internal port on the firewall. No one on the network needs access to anything other than the shares on the server. I wish to use static IPs for now.

Then you do not need a DNS server internally. Use the one that your ISP provides for free, and put that address in the first DNS server ( primary).
You can use your DNS server ( if you feel you need one ) as secondary.
Your ISP should also have at least 2 DNS servers in any case, and they should be listed before yours ( again , if you decide that you need one ).
