Need help with Vista account passwords

[Neil]

I have run out of ideas so I figured I would resort to this, I have a computer in my living room that my family uses, originally it had an admin account and a user account so I could manage the computer, set up parental controls etc. but one of my brothers isn't completely terrible with computers and googled how to make a boot disk that will load up a password cracker so that he could then use the admin account, he wont admit it but I'm certain as I see no other way he could possibly be accessing the admin account, I went as far as to disabling CMD on that user so I'm certain it's a boot disk.

My question is, does anyone know of any way to prevent this? Taking the computer away simply isn't an option and I have no idea where he would be storing whatever it is he is using, so if there is something I can do to the computer itself that'd be a far better solution.

Lock the boot order. Should stop him booting from he disk perhaps?

That could work, I'll give it a try thanks.

- Put a BIOS password on
- Remove USB and CD boot access in the BIOS
- Go into safemode, load up the Administrator account and set a password
- Disabling CMD does nothing under a standard user account

Thanks, I'll do all that.

Is there any chance he's using something within the standard user itself? I don't imagine you can do anything with the standard user but if none of this works I have no idea what he could be using.
