What to do when getting the 'Code Error 80041010 - Invalid Class' error while creating or using WMI sensors
Some customers have experience problem when trying to connect to certain types of WMI counters. The error message they get is:
80041010: Invalid Class
In most cases, the problem occurs when some required WMI classes are not properly registered in the Windows system. The solution is to (re-)register all the WMI classes.
To do so open a command prompt on the PC that you want to monitor and run the following comand:
For Windows 2000
winmgmt /resyncperf
For Windows XP and 2003
wmiadap /f
If the error 80041010 still occurs while trying to monitor MS Exchange counters, please make sure that the latest Exchange Service Pack is installed.
