there is a VPN (default) on windows server 2008, connected on LAN with LAN IP address. There a router with port forwards (47, 1701, 1723) to that server.
XP PC connects from internet to the server just fine, can't browse microsoft network (does not show LAN pc's), but I can easily access LAN's PC by entering IP or name and see the contents of sharing.
The problem is when I try to download something from that shared folder. I CAN download files smaller than ~1KB, but that's about it. Trying to copy larger files, gives errors:
"Cannot copy STHG: The specified network name is no longer available",
and error about being not able to read files. ("cant open file...")
The problem is with VPN, because sharing on he same LAN works just fine. VPN connection made by administrator account.
Any ideas how to fix this?
