A couple (2 or 3) times a day, a lot of Perfcounter IIS Application pool sensors give the message Down (Unable to connect the specified computer, or the computer is offline. (Performance Counter error 0x800007D0)) At that moments the monitored servers are running normally without having issues. I already have tried re-adding the IIS Application Pool sensors, but the issue is still there. I monitor all the application pools except _Total.
PRTG is running on a physical server and there are no other issues with sensors.
Does anyone have an idea how to solve this?
