My main system is Vista Ultimate and my secondary computer is XP. I have remote desktop from the vista to the XP BUT was wondering if there was any way to turn off the XP machine through the vista one.

If I'm reading this correctly you are remote desktoping to the vista machine, then remote desktoping to the XP one. Once you are logged into the XP machine you can simply go to start, shutdown to turn off this machine. Once that is finished your RDP session will close and bring you back to the vista machine.

You can type in "shutdown -s" at a command prompt as well.Andrew Sword, MVP
