Can someone tell me what ports I need to open on my
firewall to allow DC & DNS traffic through for a 2000
domain with active director?

Incoming for DNS you need 53 UDP & TCP, outgoing you need something like
1024-65535 UDP&TCP if you have a DC on both sides of the firewall you should
set up a VPN link because to open all the ports for AD replication makes
your firewall like Swiss cheese.

For more information please reference 179442 How to Configure a Firewall for Domains and Trusts http://support.microsoft.com/?id=179442. Keep in mind, if
the firewall is also a NAT device, this most likely will not work unless you create a VPN tunnel through first.
