Active Directory Replication Errors sensor returning the error: "The Sensor did not return an errorm

The title was cut. It follows the complete error message: An unknown error occured. The Sensor did not return an errormessage. (code: PE127)

What happens when you execute C:\Program Files (x86)\PRTG Network Monitor\Sensor System\ADSReplFailures.exe

...manually with the corresponding parameters? Same message?

I got the following message: Impersonating user xxxxx Get Domain Controller for xxxxx Invoking KCC Replication access was denied.

The user is not domain admin, but it have WMI permission, I'm monitoring lots of items through WMI sensors, like memory, cpu, etc, but only on this machine, not on the others.

Can you try it with the domain admin? AD replication state might not be readable for that very user.

Actually not... It is just a PoC, so the client hadnt want to give this permission to the user.

Is that possible to get around it?

Probably not - you could also use a local administrator on the machine and use the machine name as the domain within the device configuration.
