I have a network that has a VLAN in it, and I would like to monitor that VLAN with my PRTG. The servers don't have any firewalls running on them, and all the ports are opened on the LAN Segment.
I can ping them, however, the WMI traffic does not go through. Does anyone know why that is? The WMI tester just gives me a regular error that says: RPC port 135 not accessible. Has anyone ever experienced this problem and found a solution for this? Or have I done something wrong?
