I believe you will need information to pass in both directions, thus
necessitating bi-directional rules on the internal firewall.

What do you mean?
The member server is a Windows 2003 Terminal Server and it is located on a
DMZ.
I know I have to allow traffic from member server to DC (configured on my
'internal' firewall).
The Question:
But do I also need to open ports from my DC to the member server (on my
'internal' firewall)?
