Nokian111 - there is no Remote Desktop Application that needs to be downloaded to the host computer (the desktop). It is a part of windows. That being said, it isn't part of XP Home - only XP Pro, Vista Business and Vista Ultimate, and the Windows Server operating systems. I am not sure if there is a hack that can be done to add RDP to XP Home or not.

You might also look at a Program called XPUnlimited. There is a free version that allows you to run 3 concurrent login sessions at the same time. If it works with XP Home, this would also solve your problem. EDIT - I checked and it doesn't seem to work with XP Home

If you cannot find anyway to make RDP work with XP Home, you might be forced to use VNC - in which case there is a program that you load onto the host machine.

Good luck.
