We have a CSM system for which users have a different password than their Domain login. They are all the time locking themselves out by typing in the wrong password.
The message on the screen indicates wrong password, but hey, lets keep typing it in to see if it will work. After 5 tries the OS locks then out for about 5 minutes.
They call the helpdesk,
We log onto their computers and move the mouse around for a few minutes,
Then ask them to try again with their windows password.
