Routing & Ras – VPN – NT4 server

I have an Nt4sp6 server w/ routing and ras installed. I have 1 pc that CAN connect thru pptp vpn (win2k client). This pc can ping the server by name (thru vpn tunnel)and get a reply but i cannot see the server’s resources from this pc. Only 1 pc has this problem!

I’ve tried the net use command and I get a system error 51 – remote computer not available, net view command gets me system error 53 network path not found.
I don’t have a problem from any other pc. I’ve created an entry for this server in the hosts file, matched the ip & vpn settings with any of my other clients and no luck! Help, I already upgraded pc from win98 to win2k thinking the win2k’s stronger net component would help!!!
