I think I am having trouble with my firewalls. I can't seem to obtain anything from the DHCP server (which is on the 20.0 subnet) if they are outside the subnet 20.0. In addition none of the servers/computers outside the subnet 20.0 can join the domain either. Is it possible that the firewalls are blocking the traffic. I am not a PIX guy by any means. So any help resolving the problem would be a great help.
Here are both of my configs from my firewalls.
Also here is a quick diagram of how the topology is set up.
