I have Server 2008 R2 set up on a local network with RRAS, NAT and VPN enabled. One NIC leads to the internet, with a WAN IP. Second NIC leads to my internal network. The internal network consists of two PC's, which can view eachother over the network. I have three PC's connecting via a PPTP VPN.

All PC's are assigned an IP in the same subnet, PC's on the internal network can ping PC's on the VPN fine, and vice-versa. The internal PC's can discover eachother in the network map, but cannot discover the PC's connected through the VPN.

Any ideas as to why this would be?

In addition, there are a couple of game servers hosted on the server - one being Unreal Tournament. The PC's which are connected through VPN cannot see the game server listed in Local/LAN games, but can see it OK in the list of Internet games.

Thanks in advance for any assistance on either of these issues.

Set the WINS server as part of the PPTP VPN connection. – Steve-o Jan 14 '13 at 19:13
Is the VPN connection limiting the data being sent back and forth? Almost sounds like the ole "No NETBIOS over VPN" problem. – MikeAWood Jan 14 '13 at 19:51
Thanks for your reply. I've set up the WINS server on the VPN client's configuration. It's detected OK in the mapping, but still isn't appearing in Network. – Michael Lee Jan 14 '13 at 19:52
Do you actually have a WINS server? If so, are the internal computers using it as well? – joeqwerty Jan 14 '13 at 22:52
Yep. WINS server is set up. I configured the local machines to use it also. The remote machines show up OK on the WINS server administration snap-in. – Michael Lee Jan 14 '13 at 23:06
