Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbtool kbWinNT400sp4fix

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

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

SYMPTOMS
========

After several days of monitoring your WINS server over the network with
Performance Monitor, your server may stop responding. The only way to reclaim
the lost memory is to restart your WINS server.

If you monitor your WINS server by running Performance Monitor locally, you may
experience a memory leak in Perfmon.exe. You can reclaim the lost memory by
quitting Performance Monitor.

RESOLUTION
==========

Perform one of the following to work around this problem:

- Do not monitor WINS counters.

- Run Performance Monitor locally rather than across the network. While you
  experience a memory leak in this scenario, the memory is returned when you
  exit Performance Monitor.

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:
