I agree with Justin, try to use the offline registry editor and clear
the password.
It only takes a few minutes to crack an alphanumeric with Rainbow
tables, but it takes a while to generate the tables.
If ths system was compromised and the passwords were changed, they may
be stronger than alpha numeric.
It ounds like someone wan't trying to be to stealthy, if they changed
your passwords instead of creating a stealthy account.
What are you loking for that you cant find on the drive without logging in?

Take a look at chntpw (http://home.eunet.no/pnordahl/ntpasswd/) and
create a bootdisk with it on it. You can then just reset the pw and
take a look around.

If you spend more on coffee than on IT security, you will be hacked.
What's more, you deserve to be hacked.
