Guided by the answer on the following page: https://kb.paessler.com/en/topic/1043-my-wmi-sensors-don-t-work-what-can-i-do
I tried to setup a WMI connection on PRTG.
1) windows firewall is not activated on probe and target
2) DCOM enabled on probe and target
3) administrator user used
4) port 135 opened and range 49152-49252 opened
5) range defined in connect-oriented TCP/IP menu
6) RPC service running
The setup we have is that all ports need to be whitelisted, are there any ports missing that are needed for the setup? At this moment only ping shows up when an auto-discover is run.
