I need some advice on implementing a VPN server. We currently have two Windows Server 2003, one is a Domain controller and other one is a terminal server. Now we would like to implement a VPN, but the current hardware cannot support it so we have a low end desktop/server that we would like to use as a VPN server.
Now my question is we dont have another Windows Server 2003, although we have the following servers available:
Small Business Server -2003 and 2008
Essential Business Server
Server 2008 Foundation
Which ones of these would we be able to implement the VPN server on and integrate it with our current operating network.
Many thanks in advance, looking forward for your replies.
