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, click the following article number to view the article in the Microsoft Knowledge Base:
