Hi Ove,

Does the issue resolve, when you restart service "PRTG Probe"? If so, try adding a Windows Uptime Sensor to the device(s) and see if that helps. I know, it sounds weird, but there is still an issue we're investigating and for some sensors like this one, adding a Windows Uptime sensor helps regarding the WMI connectivity.

Kind regards,

Erhard
