They request donations, as is common, but they don't require it. The format for the command is wol xx:xx:xx:xx:xx:xx (mac address)
I export CSV files from Landesk, copy the Mac addresses from that into a .txt file, then use a script to format the mac addresses as above. Then run the bat file in the wol context. This allows me to make custom .bat files to wake up groups of computers as needed all across our campus. It's great fun to wake up 450 computers at a time. ;>
I do have a problem with computers that have gone into hibernate/suspend mode due to group policy settings though. Since we usually get the blank remote control screen after waking up a hibernating computer this way, I use a lame work-around of waking up the computer with the WOL and then using LANDesk to force a reboot before the computer goes back into hibernation. If someone comes up with a way to fix that problem without a system reboot, I'd love to hear about it!
