Error Probe remote-powershell for query Exchange Server Database

After update PRTG to Version 18.3.44.2059 we have an issue with remote powershell probes on our Exchange Server 2010. We use six sensors with the remote-powershell für checking database availability. The error is not all the time, it comes randomly for the six sensors.

The Error in full text:
The Sensor can not connect to the Device using Remote-PowerShell. Ensure that remote management is enabled on the Exchange Server and the user-name and password is correct. See http://kb.paessler.com/knowledgebase/en/topic/54353 for details. Beim Verbinden mit dem Remoteserver "Mailserver" ist folgender Fehler aufgetreten: Die Anforderung kann vom WS-Verwaltungsdienst nicht verarbeitet werden. Dieser Benutzer ist zur gleichzeitigen Ausführung von maximal 32 Shells berechtigt, diese Anzahl wurde jedoch überschritten. Schließen Sie bestehende Shells, oder erhöhen Sie das Kontingent für den Benutzer. Weitere Informationen finden Sie im Hilfethema "about_Remote_Troubleshooting".

I changed also the value on the Exchange Server for PowerShell MaxConcurrency from 18 to 32 , but this solved not the Problem.
Anyone have an idea or the same problem?
Greetings
Robert

Hello Robert,

It means that the number of opened shells exceed the number of allowed shells for this user. I would like to increase this number. Please connect to the affected Server, open the Powershell and run the following commands:

cd WSMan:\localhost\Shell 

Set-Item .\MaxShellsPerUser 50

Please let us know if the Sensors work fine afterwards.


Kind regards,
Birk Guttmann, Tech Support Team
