TITLE   :AV in win32k!HMMarkObjectDestroy in Japanese and Korean WinNT
PRODUCT :Microsoft Windows NT
PROD/VER:WinNT:4.0
OPER/SYS:
KEYWORDS:kbWinNT400sp4fix

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Server version 4.0 
 - Microsoft Windows NT Server, Enterprise Edition version 4.0 
 - Microsoft Windows NT Workstation version 4.0 
 - Microsoft Windows NT Server version 4.0, Terminal Server Edition 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you run the Japanese or Korean versions of Windows NT 4.0, the system
displays a blue screen error message. When you examine the call stack, you see
an access violation in either of the following:

   win32k!HMMarkObjectDestroy

   win32k!HMAllocObject

The blue screen error message would be displayed as a STOP 0x1E in Win32k.sys

   STOP: 0x0000001E ( 0xC00000005, 0xA0036FC2, 0x00000000, 0x00000004)
   K_MODE_EXCEPTION_NOT_HANDLED address 0xA0036FC2 in Win32K.sys

CAUSE
=====

HMAllocObject() is not supposed to run in parallel, but it was being called
simultaneously from multiple threads:

HMAllocObject() <- GetCPD() <- _GetClassInfo() <- NtUserGetClassInfo()

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or
Windows NT Server 4.0, Terminal Server Edition. For additional information,
please see the following article in the Microsoft Knowledge Base:

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT
Server 4.0, Terminal Server Edition. This problem was first corrected in Windows
NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition
Service Pack 4.
