Hi, I'm trying to add the Active Directory Replication Errors sensor on our DCs in PRTG. When I add the sensor, though, I get this error: "Could not create the sensor Active Directory Replication Errors on device ..."

The probe is part of the same domain as the DCs, the credentials are set in the root but I also tried to set them in the device itself (I'm using a domain admin), .NET is installed (v4.6) and the firewall on the DC is off. I'm getting the same error on all DCs we have (4 in total). Both the probe and the device are Windows 2016.

The probe is part of a cluster, we're running version 18.1.37.12158+

What can it be?

Thank you, Marco

Hello Marco,

Please try to manually execute the sensor in an administrative CMD on the host where the probe is installed. Start the .exe file with these parameters:

\PRTG Network Monitor\Sensor System\ADSReplFailuresXML.exe -c="<host>" -l -u="<domain>\<user>" -p="<pw>"

Use the exact same user which is also used in PRTG, which results do you receive?

Best regards, Felix

Thank you, the error was due to the fact that the password contains a ", which is not escaped apparently when launching the executable. I tried another user, with no " in the password, and it worked perfectly.

Hi Marco,

Interesting, thanks for sharing your findings. I'll raise an internal development case to see if we can escape the comma properly.

Best regards, Felix

Hi Marco,

The sensor uses a WMI query to pass the credentials in double quotes. It appears to be not possible to escape characters inside this query, see here.

Best regards, Felix
