If this Win XP PC is shut down by holding down the power button for 8 seconds, it can be WOL'd by sending a magic packet. If I then remote desktop into the PC and shut it down, it completely powers down, and no longer can be WOL'd. Any idea what would cause that behavior?
I really don't have any other details at the moment -- the PC is powered down right now and I'm the remote user.
To do the WOL, I'm using the same short Python script that I have been successfully using on another PC for the past 2 years, just with a different MAC plugged into the script.
