SYMPTOMS
When you try to use the System Monitor tool on your Microsoft Windows XP-based computer, some of the performance objects and counters are not available. For example, the following objects are not available in the Performance object list:
 * Cache
 * Memory
 * Objects
 * Processor
 * System

Therefore, you cannot collect information about their associated performance counters.

If you try to use Windows Management Instrumentation (WMI) to query the counters, you cannot obtain any information for the missing performance counters.



CAUSE
This problem occurs if your Windows XP-based computer is not configured to use a virtual memory paging file.
