Hello there,

If you want to change the security context for executing the script, you can do so in the script sensor's settings, so that it will be executed using the account configured in "Credentials for Windows Systems" located in the device's "Settings" tab.

Kind regards,

Erhard

Hi Erhard,

thank you for your Reply. Sadly i already tried this and still getting the Same Error

New-PSSession : [ixxxxxxxt] Beim Verarbeiten von Daten vom Remoteserver "xxxxxxxxxxt" ist folgender Fehler aufgetreten: Benutzer "xxxxxx/xxxxx/PRTGServer" ist keiner Verwaltungsrolle zugewiesen. Weitere Informationen finden Sie im Hilfethema "about_Remote_Troubleshooting".

It Seems that PRT is executing the Script with the Computer Account and not wiht the Credentials i did supply, i even used the DOmain Administrator.

Hi there,

Did you make sure to enter the regarding credentials in device's "Settings" tab in "Credentials for Windows Systems"?

Open services.msc and check the properties of service "PRTG Probe". Check tab "Log On"/"Anmeldung". Usually it is set to "Local System". Try setting there manually the domain admin to check if it works then.

Kind regards,

Erhard

Hi IgetYaAll,

Your problem likely is the NEW-PSSESSION command - I highly recommend to load credentials from another file and try it this way. The KERBEROS parameter could interfere there as well, but that's another story.

Credentials can be saved in a file and loaded from there - see the following link for details: https://blogs.technet.microsoft.com/robcost/2008/05/01/powershell-tip-storing-and-using-password-credentials/

Of course, in theory this would be a security hole.

If you want to avoid this all together, why don't you just install the Exchange PowerShell extensions to your PRTG probe server or install a remote-probe on the Exchange and have the script execute there? This eventually would avoid the whole struggle with the remote session itself.

Regards
