I have a problem with one of our customers: I added machines with an Auto discovery, I can ping machines but can't ad any WMi sensor.
I tried with wbem test and WMItester, and same error every time : The RPC server is unavailable.
I checked https://www.paessler.com/knowledgebase/en/topic/1073-what-are-the-most-common-errors-when-monitoring-wmi under 800706BA - RPC Server Is Unavailable, but nothing helped.
Here is my setup : connection with IP ( i have no dns resolution to customer), is this a problem? Account for WMI connection is member of domain admins Connection trough VPN
There's something odd: I checked some machines in my own network and It works (wbemtest).
But with Wireshark, I noticed that when i connect to customer with WMI, after a frame called RemoteCreateInstance response, my server is trying to call a service: kv-server on port 3360. Any clue on that?
This didn't happen when i connect to my machines.
