@Robert P. We had an issue where we could not see the network data.. Currently you can exclude network rules in the settings of the host, or you can also disable the WinPcap and that will prevent the network data.
In our case WINPcap was disabled so we were not getting any network metrics on a select few hosts.
I agree with this. I think your best option is to disable wincap. If you go this route you should first perhaps disable network traffic monitoring (Settings->Monitoring->Monitored technologies->Network traffic switch off), disable autoupdates (because winpcap will be installed again) and then uninstall winpcap.
