SYMPTOMS

If you install Windows NT with a US-Dvorak keyboard layout and change the keyboard to a standard US-QWERTY keyboard and match the configuration in the International or Regional Settings tool in Control Panel, you may receive the following error message when you attempt to log on:
The system could not log you on. Make sure your username and domain are correct, then type your password again. Letters in passwords must be typed using the correct case. Make sure that Caps Lock is not accidentally on.

CAUSE
