Jack, I've had VPN and RDP and Logmein. Bert is right, there are over a dozen options to remote in.
I find Logmein the simplest and easiest.
It's very fast and simple. You are doing everything in real time on the computer in the office. And you have full control over that computer to do anything you would do as if you were actually in the office.
You only need internet connection, I use it from the E.D., while on vacation or traveling, and from my bedroom. Basically from wherever and whenever you wish.
You can also log into any computer (i.e. all the office computers, the server, your home PC) and perform diagnostics or repairs, run any program.
My recommenedation for you is Logmein.
