When you use Microsoft System Center Operations Manager 2007 to monitor system performance on Windows Server 2008-based computers, a memory leak occurs. Specifically, this memory leak occurs in the performance counters that are used by System Center Operations Manager 2007.

Note: Any applications that use performance counters in Windows Server 2008 may also experience this problem.

In Windows Vista, the Windows Filtering Platform (WFP) includes a Performance Monitor counter that displays how many network filtering policy providers are registered on the computer. However, this counter displays is more than the number of audits that you find in Event Viewer.
