Hello,
Basically what her father did is use that control userpassword2 setup to have her PC auto logon and log right into the network. What you need to do is get it logging on with her user profile again. Can do it right there. But be careful with that option as it will just load right to her desktop with out being prompted for a password.
When that screen comes up click the box for user must enter a password. This should allow you to use the regular User Control selection screen to setup your options.
Cheers,
Mak
