SYMPTOMS
After you log on to your computer running Windows NT 4.0, which is configured to use the logon screen saver, the computer may stop responding (hang) and the following STOP blue screen error message may be displayed:

STOP 0x0000001e (0xc0000005, 0xa306cc1a, 0x00000000, 0x00000004) KMODE_EXCEPTION_NOT_HANDLED



CAUSE
The blue screen error message is caused by a corrupt or invalid handle that is being used by Dr. Watson to display the dialog box for OK or Cancel after a program has ceased functioning properly. The program that is starting Dr. Watson for this particular issue is always the logon screen saver which uses the Logon.scr file. The screen saver causes a fault for the same reason as Dr. Watson, a corrupted or invalid handle. Because Dr. Watson is the debugger for user-mode processes if a problem occurs in the debugger, the kernel attempts to handle the fault. If the kernel cannot handle the fault, a blue screen error message is generated.



RESOLUTION
To resolve this issue, click to clear the Dr. Watson Visual Notification feature:


 * 1) Click Start, click Run, type drwtsn32, and then press ENTER.
 * 2) Click to clear Visual Notification, and then click OK.
 * 3) Restart the computer.



STATUS
Microsoft has confirmed that this is a problem in Windows NT Server 4.0, Terminal Server Edition.



MORE INFORMATION
Turning off the Visual Notification of Dr. Watson option prevents the display of the OK/Cancel dialog box after a program has caused a fault. Because of a corrupt or invalid handle, Dr. Watson cannot display the window properly and Windows NT displays the blue screen error message.

With Visual Notification disabled, when a programs does not function properly, a User.dmp file is generated. With the option enabled, there are no User.dmp files generated.
