TITLE   :NetMon Fails on Multiprocessor Windows NT Server Under Stress
PRODUCT :Microsoft Windows NT
PROD/VER::1.2,4.0,4.0a
OPER/SYS:
KEYWORDS:smallbiz

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

 - Microsoft Windows NT Server version 4.0 
 - Microsoft BackOffice Small Business Server versions 4.0, 4.0a 
 - Microsoft Windows NT Workstation version 4.0 
 - Microsoft Windows NT Server, Enterprise Edition version 4.0 
 - Microsoft Systems Management Server version 1.2 
-------------------------------------------------------------------------------

SYMPTOMS
========

Using Network Monitor to analyze a network interface on a multiprocessor
computer running Windows NT under heavy stress can result in the following STOP
error message being displayed:

   STOP 0x0000000A (0xf8e09000, 0x00000002, 0x00000001, 0xfe2d0397)

The exact address where the STOP error occurs may vary, the fourth parameter will
be in the range of Bhnt.sys.

CAUSE
=====

Under certain stress circumstances in a multiprocessor environment, Network
Monitors' NDIS-related packet receive handler will leave a data buffer
vulnerable to multiple processes. This results in damaged buffer metrics and a
buffer overrun.

RESOLUTION
==========

A supported fix that corrects this problem is now available from Microsoft, but
has not been fully regression tested and should be applied only to systems
