I have a computer that when it starts I get a small box with a message that says "this computer is configured to require a password. In order to start up please enter the start of password below. Then there is a text box to enter a password with 2 buttons one says okay and the other says restart.
I have tried to replaced the LSASS.exe file from the original i386 directory and that has had no effect. This problem also shows up when I press F8 and boot into safe mode with command prompt. I have also tried to remove the passwords using a password removal tool with a Linux based system.
This problem started after an unsuspecting person took a call from people who said they were from "Windows" and indicated that this computer was sending out information over the Internet. That person allowed the caller to log onto the computer and once she realized that it was a scam she unplugged the computer from the Internet and shut it down.
This system is running Windows XP home premium with service pack 3.
