can not add Windows Print Queue Sensor




I want to add our first "Windows Print Queue Sensor". But it doesn't work. :-(

When trying to add it to the parent device, it always throws this error: " Cannot access printserver
SECRETSERVER.mysecretdomain.lan "

It's not possible to add this sensor to the device. :-( Other WMI sensors work fine.

I already checked it via the Paessler WMI Tester with this Query:

SELECT * FROM Win32_PerfFormattedData_Spooler_PrintQueue

--> It worked successfully in the WMI tester, I got a list of all print queues with additional data.

I used the same domain credentials in WMI Tester as in the settings of the parent device. The WMI Tester was running on the PRTG-Server. As the used probe also is running.

We use PRTG version:

Our PRTG-Server with probe runs unter Windows Server 2016 Standard. This machine is NOT in our domain. The target machine runs under Windows Server 2016 Datacenter. This machine is in our domain.

How can I get this sensor running?

Hi there,

Head to "C:\Program Files (x86)\PRTG Network Monitor\Sensor System", there you find PrintQueue.exe, start it manually, it will show you then which parameters it requires to run. Run it with parameters then in command prompt, what do you get then?

Kind regards,
