Win 10 April 2018 update

I installed the April 2018 update on a workstation yesterday. Today I first upgraded PRTG to 18.2.40.1683, but still all was working well.

Then I updated the "server" running PRTG with the April 2018 update. After that, the workstation I updated can't send data. I get the dreaded "A connection could not be establised - PE015" error.

Just to check if it was a fluke, I updated another workstation. Same thing. It worked, then it did not.

I usually have to do these tricks: https://kb.paessler.com/en/topic/203-how-can-i-monitor-wmi-sensors-if-the-target-machine-is-not-part-of-a-domain … to get PRTG working again after huge windows updates, but I checked every setting and it should be OK.

And on the PRTG "server" I've used the WMItest.exe tool. Which can read data from both machines.

What am I missing? Is it something with the April 2018 update?

Hi there,

To receive a more detailed error message, could you please forward this article to create Probe Status files and forward the files to support@paessler.com?

Thanks in advance! Best regards, Felix

What finally worked was setting up the PRTG Probe service to use the local computer account, instead of the default "service" account.
