I am trying to connect two sites via a vpn through a cisco 2600 router. I have the router all set up and working (can ping the ip's at the other site. It is connected via a T-1 Point to Point connection. I am trying to connect a Windows 2000 domain and a Windows NT 4.0 domain, but cannot see the other domain in Network Neighborhood. How do you get it to see the other site and visa versa?
