Ports needed to be open for Windows 2000 Domain Controller

We are installing a Windows 2000 domain controller on one of our DMZ's. I need to know what port/ports on the PIX will need to be open to the DNS server so that the domain controller can dynamically register its SRV records.

Port 53 any others?

Thanks in advance.

port 53 yes, but you prob need NetBios ports 135-139 tcp and udp also. And if you're doing NAT, make sure the WINS is staticly configured with all the IP addresses.
