Q279247: Access Violation Appears During Shutdown After You Use IIS 5.0

Article: Q279247
Product(s): Internet Information Server
Version(s): 5.0
Operating System(s): 
Keyword(s): kbWin2000SP2Fix

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

- Microsoft Internet Information Server version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use Internet Information Server (IIS) 5.0 and then shut down the
computer, you may receive the following access violation error message:

  ModLoad: 73930000 73940000 D:\Winnt\System32\Clusapi.dll ModLoad: 689d0000
  689dd000 D:\Winnt\System32\Resutils.dll ModLoad: 6a750000 6a76e000
  D:\Winnt\System32\Mtxoci.dll Access violation - code c0000005 (first chance)


CAUSE
=====

This behavior can occur when a race condition occurs in the ATQ Context
structure while the computer is shut down. The ATQ Context structure contains
information in .dll files that are associated with any client operation that is
running on an ATQ thread. When you shut down IIS, the main thread quits, but the
ATQ thread remains unmapped to shutdown, which causes an illegal close. When an
illegal close is performed, the ATQ Context structure is invalid. Any pending
operation may not succeed, and the access violation error message appears.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows 2000. For
additional information, please see the following article in the Microsoft
Knowledge Base:

STATUS
======

Microsoft has confirmed this to be a problem in Internet Information Services
5.0. This problem was first corrected in Windows 2000 Service Pack 2.
