Blue Screen When Closing Kernel Mode Handles from User Mode (160650)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q160650 SYMPTOMS
User mode programs that close a handle that was opened up by a kernel mode
component may cause a blue screen error message.
CAUSE
In Windows NT 3.51, if this happened, the handle became invalid. In Windows
NT 4.0, if a kernel mode component closed an already closed handle, a blue
screen error would occur. A user mode application has no way of knowing who
closed the handle. A user mode application should never close a handle
opened by that application in kernel mode.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows NT
version 4.0.
This problem was corrected in the latest Microsoft Windows NT 4.0 U.S.
Service Pack. For information on obtaining the service pack, query on the
