Symptom 1

When you query some ASP.NET-related objects by using Windows Management Instrumentation (WMI), no values are returned. For example, no values are returned when you query one of the following objects:

• Win32_PerfRawData_ASPNET_ASPNET
• Win32_PerfRawData_ASPNET_2050727_ASPNETAppsv2050727
• Win32_PerfRawData_ASPNET_ASPNETApplications

Symptom 2

If you run the Perfmon.exe command together with the /wmi option, no ASP.NET 2.0 performance counters are listed. However, if you run the command without the /wmi option, the following counters are listed:

• ASP.NET Applications/Cache % Machine Memory Limit
• ASP.NET Applications/Cache % Process Memory Limit
