How to run a DC over a VPN link?

[andyds]

I have a MS Windows 2003 Enterprise R2 Server acting as a domain controller on our main site of about 100 users. It also acts as a DHCP, DNS , file and print server. I have 4 remote sites with around 20 users on each site. I have WatchGuard Firebox X Edge boxes (v 7.5.2) on each site. Each site is successfully connected to every other site via a VPN tunnel and all the tunnels are always open.

I can’t ping my domain controller from remote sites. I don’t have any firewall running on the server. I can however ping other servers using their internal IP addresses.

Can anyone tell me what steps I need to take to allow me to run my domain controller from one site so it serves other remote sites via VPN? Do I need to do a ‘add route’ command on my domain controller? Please help, Ineed it!

It doesnt sound like a WG issue. You might want to check MTU problems between your DC´s. And i assume you have configured subnets under sites and services for your remote DC´s
