I've setup a device with 6 sensors (Ping, CPU, memory, disk free, network, uptime). 4 of the 6 sensors work except disk free and memory which both report "Connection could not be established (800706BA: The RPC server is unavailable". Windows firewall is turned off. DCOM and WMI permissions are set.
I'm at a loss. Please help.
PRTG version 188.8.131.525
