Ok, I have a very very technical problem that I need help with. I have set up a PPTP VPN on my companies network using Routing and Remote Access on 2000 server. I have set the PPTP filters, opened port 1723 on the firewall and directed traffic through it to port 0 on the server. Also I have enabled protocol 47 (GRE) and am using DHCP to assign IP addresses, so I dont need static routes (and yes, I installed a DHCP relay on the VPN server).
Here's where I'm at. The tunnel uses 128 bit encryption and the VPN can authenticate a user based on the policies I've set. HOWEVER - once logged in I can see nothing on the server. I have spent alot of time, however I cant seem to come up with a solution. The DHCP server does assign a mask of 255.255.255.255 to the VPN client while assigning B class to normal LAN users, however im not sure that this is the problem (if it is I cant figure out how to fix it).
Please help!

Well, it sounds like you configured the service correctly. After confirming if the configuration is truely accruate, there are still a few questions.
Are the clients (PPTP) windows 9x, NT 4, ME, 200, XP or a mix of all). This affects the functionality of resource resolution for the clients.
If you are remote and PPTP in, then resource resolution should be local DNS, Wins first local to remote user), then if that resource is not found goto gateway.
At that point the Gateway should be Your PPTP DNS or WINS ip, if it goes to the Local Remote Users Geteway it goes to the Internet and well NOT find any of the remote networks resources. There is a setting on the PPTP client that says Use Remote Gateway or do not use remote gateway (something like that)

Good luck.

fixed it, I had the filters set up if it was outside of the firewall but its on the inside. One note though, you were on track but have it backwards, if you end up using the remote networks default gateway you can still browse the network, but you are unable to browse the regular internet.
