Hi all. Does anyone have any experience configuring a firewall (PIX 515 specifically) and Windows 2003 servers to allow trust connectivity between two domains through the firewall? I currently have a server in the DMZ that needs to authenticate users on a domain inside the firewall. The DMZ server can't contact the domain inside of the firewall. I read this article on MS site, but it doesn't seem to be the problem, as I currently have ALL TCP/UDP/IP ports from the DMZ to the inside open for testing. Any tips/suggestions?
