Yeah, it's like their documentation for making Active Directory work through a firewall. MS's recommended solution: Run a PPTP server on one of your domain controllers, and make other DC's have a PPTP VPN tunnel to it through the firewall. What a total bunch of shit. MS is good at designing protocols that make it a nightmare for firewall admins. Jay
