Hmm, not sure about this...

Haven't tried but lets say recovery console is running as system which can
read the SAM and it lets us copy it off the box to a share or usb or
whatever, if we can get it off i'm guessing we can rip out the hashes for
the users and attempt to crack them, spray them about or whatever...

But changing one so we know the password and then putting it back, doubt
this will work will it, as essentially we are changing the SAM file anyway
aren't we when we create a new legit user through net commands and it
discards this change when we reboot, or are there 2 SAM files? One in live
environment which dissapears and the real one...

Pass, i will try it out again when i get 10mins..:-)
