Can’t Connect To Some Servers

I’ve got an NT 4 server set up as a VPN server. I’m connecting with W2K Pro over the Internet. I can see everything in Network Neighborhood but I can only map drives or browse shares on the NT servers, not the W2K servers (non DC machines – no AD in the domain).

It’s a single domain and everything is on the same subnet.

First one with the right answer gets 200 points.
