As long as it's just sleeping there is ways to power it on. Just like your mouse can wake it so can signal from networked device.Freddy wrote: Yaaa... but wouldn't I have to leave that machine booted & running all the time?
This is going to depend on the mobo and XP, but you can start by going into devices . Look under network adapters, there will probably be two of them if you have ethernet and wifi. Right click and select properties, look under the power management tab.
If that is not available another option here would be to schedule it to power on,of course you would only be able to login into when it was awake.
