Even if you have two NICs, be very wary of using the VPN server option in
the wizard. This option should only be used if the server is to be used for
VPN ONLY. It will set up filters to block all traffic which is not VPN
related.
What you want to do is possible, but there are plenty of traps.
1. Your server does not have a public interface, so you will need to
connect to your router's public interface, and forward the PPTP traffic from
the router to the server (tcp port 1723).
2. You will need to configure your server for remote access in the RRAS
wizard (or use the manual config option).
3. Test the connection using a local LAN client, then try connecting from
a remote site. It will fail if your router blocks GRE (IP protocol 47).
4. Making an AD DC a remote access server can cause problems for your LAN
clients. As soon as a remote client connects, your server is multihomed, and
this can upset all sorts of things. See KB 292822 .
