TITLE   :Cluster Node with Heavy Disk Stress Does Not Shut Down Properly
PRODUCT :Microsoft Windows NT
PROD/VER::4.0
OPER/SYS:
KEYWORDS:kbWinNT400PreSP7Fix

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

 - Microsoft Cluster Server 
 - Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you attempt to restart a node of a computer running Microsoft Windows NT
4.0 Cluster Server that is subjected to a large amount of disk activity, the
computer running Windows NT 4.0 may not shut down properly. As a result, Cluster
Server may stop responding (hang).

CAUSE
=====

This behavior can occur because the Network Driver Interface Specification
(NDIS) drivers are being shut down before the Cluster service. This behavior can
cause cluster network requests to stop responding.

RESOLUTION
==========

testing at a later time, to further ensure product quality. Therefore, if you
