Cannot Log On After FilterKeys Option Enabled

 * }

 * Microsoft Windows NT Server version 4.0
 * Microsoft Windows NT Workstation version 4.0

SYMPTOMS
The system does not appear to respond to keys pressed at the logon screen (system beeps), and you are unable to log on.

CAUSE
The FilterKeys Accessibility option has been enabled for the logon session. With FilterKeys enabled, keys need to be held down for 1 second (default settings) before the system registers the keystroke.

RESOLUTION
To resolve this issue, do the following:


 * 1) Press and hold the Control (CTRL) key until the system beeps twice.
 * 2) While still holding the CTRL key, press the ALT key until the system beeps twice.
 * 3) While still holding these two keys, press the Delete (DEL) key until the password prompt is displayed.
 * 4) To enter your password, hold down each key for two beeps; the asterisk (*) is displayed indicating the key has been entered. Then, move on to the next character in the password. If you need to use the SHIFT or CTRL key, press and hold the key for two beeps before pressing the second key. Use the mouse to click OK when the password is entered.
 * 5) After you are logged on, click Start, click Settings, and then click Control Panel.
 * 6) Double-click the Accessibility icon, click to remove the check mark from the FilterKeys check box, click OK, and then click Yes to the Do you want to save the current settings as the default for new users and the login prompt? dialog box.

STATUS
This behavior is by design

MORE INFORMATION
After enabling FilterKeys, the user is presented with a dialog box stating:

"Do you want to save the current settings as the default for new users and the login prompt?" If you select Yes to this prompt, FilterKeys will be enabled for the logon session.

If you select no, FilterKeys will be enabled only for the current user's profile; logging on will not be affected.
