I'am considering something like it, but found a drawback:

Steps OK:
* enabled wol on a machine
* shut down (normally from windows).
* send magic packet
The machine starts ok..

Steps BAD:
* enabled wol
* cut power, restore power
* send magic packet
Nothing happens...


I was thinking on configure the PCs to power on after power fail, but
that will make a system to get powered on at any time, not only on the
maintenance window.

i think it would be good for ours, the sysadmins using wpkg, to share
thoughts on other ways of executing cscript and keeping users happy.


best regards
