[LOGic] More on remote operation

Dan:

Do you ever need to warm/cold boot the PC's (and peripherals), even if 
momentarily, to break a lockup, reestablish network connections, etc., etc.? 
Does coldboot actually remove power from the secondaries of the power 
supply?

I'm not trying to give you a hard time here, I'm just trying to explore how 
much "exercise" PC's running 24x7 (especially remote PC's) require. And am 
not so much exporing fire risk (altho that's always worth some study) as I 
am just lockups, debugging, and other voodoo associated with networking.
