"O.K.... you get in to work this morning and your system is on...
sitting there with it's eyes wide open and you could swear "I turned
that thing off before I left..." happen to you yet? Here maybe what's
happening... some system(s) on our backbone is/are sending out "Magic
Packets"... this technology is used to remotely wake up a sleeping or
powered off PC on a network. This is accomplished by sending a specific
packet of information, called a Magic Packet frame, to a node on the
network. When a PC capable of receiving the specific frame goes to
sleep, it will enable the Magic Packet mode in the LAN controller, and
when the LAN controller receives a Magic Packet frame, it will alert the
system to wake up.... so if say someone wanted to REMOTELY ADMINISTER
your system and you turned it off.... Voila! I'm in"
