Question for those of you who have done password recoveries/resets.

I'm working on a computer that needs to be unlocked (users are always forgetting their passwords). I've tried several password recovery/clearing tools, from Rob's TRK to UBCD to a copy of OPHCrack. I've been able to use all of these in the past to reset a password, but this time I'm having a weird problem.

When I boot up the computer normally, I get to a login prompt with a username of "Shelly." When I load up any of these password recovery applications, that account isn't even listed. I can reset the administrator account's password, but I can't seem to be able to access the administrator account...

Any ideas why the account isn't showing up?

*Edit*
Nevermind! I totally missed the option in TRK to enable the Administrator account. Thanks again, Rob, for mentioning such a great resource. I've used it several times since you linked me to it in this thread.
