Hi all,

We created a WMI CPU Load Sensor to monitor a Windows 2008 CPU status, but the following error is received:

80041010: The specified class is not valid

This issue occurred once before, and it was resolved by resigstering some WMI dll/classes, which we now forget which dll/class is.

Do you have any clue? Or any solution with this issue?

Thanks and Regards, Dorothy

This means that one this one particular host, the necessary WMI Class is not available or broken. Please have a look at our WMI Troubleshooting-Articles: My WMI sensors don't work. What can I do? and The Repair List for WMI problems

I agree your analysis. Hence, my concern is which WMI class/dll does the WMI CPU Load Sensor query. I suspect this issue can be resolved after registering these particular components.

Thanks, Dorothy

Dear Dorothy,

the The Repair List for WMI problems-Article lists a few options to refresh or re-register WMI-Components. We would recommend to try these in a general way, rather then searching for specific classes/components.

Best Regards.
