Computers Restarting after Shut Down Command

[Ixixly]

Hi All,

Long time reader, first time caller!! I use a bunch of AHK Scripts to automate some functions at work using a Numpad, one of the functions is being able to shut down the computers from the Numpad via a single Keypress.

I've noted that 3 out of my 7 computers after being shut down using this script will not actually full shut down, they infact Restart and I can't for the life of me figure out why. All 7 computers are identical in Hardware and mostly Identical in Software and all Identical in Function, but for some reason these 3 computers will always restart instead of shutting down.

Can anyone here shed some light on why this might be happening or someway to figure it out? Is there a log that shows what caused the computer the power up or perhaps a log confirming which command is being sent prior to shutdown?
