Here is the whole problem... I have run into users that have downloaded a bootable floppy with chtnpwd or some tool like that on it, that allows a user to boot to a floppy and change the admin password. No matter if you rename the account, it tells the user what the account with admin rights is.

I want to disable/remove this account and have only Doamin Admins with the rights to administer the computer / a private group membership I will allow later on all local machines that they will be unable to trace. But as long as that built in account is there... all of this is pointless. PLEASE HELP
