Hi,
We're getting this error on number WMI sensors that monitor Windows services. Restart of WMI service and subsequently affected service fixes the problem but it keeps coming back regularly. How can we fix this?
Thanks

Hi,
I have the same problem on two servers. Just updated to PRTG 16.1.21.1258+ and still the same. WMI Memory e.g. works on this servers but not WMI Service...
Any ideas?

Hi Hohenstein,
The recent update (16.1.21.1258) fixed an issue that caused otherwise working WMI Service Sensors to stop receiving data under certain circumstances.
What you (and Tomas) describe is something different. Keep in mind that errors/responses like these basically come from the targeted machine and are only "reflected" by PRTG. You can use WMI Tester to test the queries manually, which can be found here. Also be aware that not every query is the same and if one WMI Sensor works on a target, it does not imply that all other WMI queries from other sensors will be successful, too.

Kind regards.

Hi Tomas,
I don't know which version you are using. With 15.4.21.xxxx we have a bug that leads to WMI Service Sensors turning grey/not receiving data after restarting the monitored service. This will be fixed with the first 16.x version planned for this week. However in your case it might be something different, see also this post from Microsoft. Since you've also sent us an email, I will also answer to that with further information.
Kind regards.
