How to diagnose PE018 with Windows Update Sensor




I'm monitoring eight remote servers, all of which are Small Business Server 2011 (e.g. Windows 2008 R2). All have a remote probe installed (v15.x.x.x). The PRTG Core is on a 2012 R2 box.

For seven of the remote probe machines, The Windows Update Status (Powershell) command is working great, but for the last machine I only ever get a PE018 error (timeout). On all machines, including the failing one, the output of $PSVersionTable is the same.

There's a thread here:


but only one reply and that reply doesn't seem to change anything.

Is there a way to diagnose what might be wrong, perhaps a log file somewhere on one of the machines?

Many thanks

Exactly configured the same way? Are you running the sensors directly on the probe device (with the IP or a device configured under that probe?
