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.
