VPN is a private network established on a public network (like Internet).
for example you can connect two branch office LANs through Internet by a VPN, and yet other users of Internet can not see your private LAN connection.
there are some standards for making a VPN, like PPTP, L2TP, IPSec, ...
On NT & 98 you can use PPTP.
