Password needs to be reset and user disappeared from logon screen

A friend at work has given me their laptop to look at as their password stopped working (or she forgot it). I tried using the Trinity Rescue Disc to reset the password as it was showing the account as being locked. Now the only option on the logon screen is the guest logon.

Could someone help me restore her username as a logon option and give a way to reset her password?

Her account as far as I'm aware is the administrator account otherwise if just use that to have reset her account.

Thanks in advance...

Did a boot using Hiren Boot CD, cleared password and then needed to go into safe mode and use regedit to reset an error on the user profile, all sorted now :)
