I support some friends via logmein when they have pc issues. I heard there is a way to remotely power on a pc that is powered off, is that true? does it differ by operating system, windows xp or 7 etc?

The end user also needs to usually have a static IP address or use a service such as no-ip.com or similar. Doesn't work too well if their dhcp address changes often.

I just leave the computers turned on 24/7 AND set the BIOS to have the computer come back on after a power failure. Rarely do I have to ask someone to reboot one of them. And, if telnet is still working, you may be able to use a shutdown -r command to reboot remotely.

To add to the other comments, if you have access to a PC on the same local LAN through any means,; LogMeIn, GoToAssit, RDP, or other, you can use Solarwinds's free WOL tool:

There are also a few routers that support a WOL feature. With those you log into the router and send a magic packet to the appropriate MAC address. DD-WRT firmware for a router is one option that supports this.

Using simple port forwarding does not work for WOL, you need a router that supports sending the protocol from itself.

If by any chance you have a Small Business Server on the site which supports Remote Web Workplace there is an add-on to allow you to Wake a PC
