We currently have a smaller office network, comprising of a Win 2003 Server and a approx. 50 WinXP Pro clients. The server is setup as a domain controller. Users have a network drive and roaming profile - users are encouraged to save all their docs into their network drive so they can access them from any client in the building. Network has internet access etc.
What I want to do (I presume this is how you would do it) is to setup a VPN, so users are able to login to the domain controller remotely from their windows xp laptops and then in turn access their documents stored on the server. In short, how do I go about setting up this software VPN?
