You will need three different Windows 2003 servers and at least one remote client for creating a VPN. You need Windows XP up an running on the remote client's machine. The first Windows 2003 server is basically an infrastructure server that should act as a domain controller, DHCP server, DNS server and certificate authority. You do not have to buy a server in case you already have a Windows 2003 network in place.
