You can also use logmein Basic which is free up to a certain amount of computers. I believe 5 pcs. https://secure.logmein.com/createaccount.asp
LogMeIn is one of the many choiced that one has when deciding on remote access software. LogMeIn Basic is freeware, and allows you to install the client onto a single machine that can be access via the LogMeIn website through a browser. With a small memory footprint, the program does not interfere if you leave it up while you decide to load up a game.
Although the full paid version of LogMeIn automatically allows you to transfer files by dragging, stream audio, network printers, etc, the free version has none of these features. Although there is a free 30 day trial, these features are nice but not necessary for basic remote access needs.
Bandwidth is a large factor in the speed and refresh of LogMeIn, and although I run fiber optics at home, there is still a small amount of lag between connected clients and the server. Loss of some keystrokes can be a pain if you are a fast typer, but this is no different then Windows Remote Desktop.
