VPN

Question

I have 2 workgroup/LAN's that I'd like to connect using a VPN. I have successfully configured the routers so that I can Ping from the remote location to the main location. I can also ping the other way. However, I Remote Desktop doesn't work and I don't know how to transfer files from network to network ... which is the real reason I'm going through this whole thing. I do not run file servers ... rather both are just peer-to-peer networks.Help.N.
