Domain in the DMZ

I just recently worked with a vendor to upgrade a Windows NT domain
into a Windows 2003 Active Directory Domain. I currently have a empty
root for security purposes and a child domain with all of our
resources. A contractor will be arriving to move Active Directory into
the DMZ. I would like to get a head start on the AD move prior to his
arrival. I have very little experience with firewalls, so i'm at a
disadvantage. What all is needed to make this happen?
Any suggestions and or direction will be greatly appreciated.

May I ask exactly why would you want to put a DC that is part of your
private internal protected network and domain and then expose it to the
Internet (firewall or not)?

There are about 29 ports, not to mention the dynamic emperical response
ports UDP 1024 and above, that AD requires for DC to DC communications, and
about 15, including those UDP ports, for client to DC communication. Do you
want to open them up? That would expose too much.

If you are trying to allow access from remote users, consider a 3rd party
VPN solution, such as a Cisco PIX (which I like, but of course I assume the
firewall you are installing has that feature) to create tunnels for your
users to access internal resources, rather than putting a DC outside.
