I'm asking about when u enable a machine at your environment to detect unmanaged clients, my doubt is if can trust at the report, because most of IPs that i get from the report when i look throughout to the machine most of have AV client installed.

Thanks!

unmanaged detector report wont be accurate it will report printers and  routers, any machine with does not have sep installed in the network.

try these steps to clear the unmanaged detector report and run it again

remove the client machine as unmanaged detector

put in a new test group.update the policy

put it back to the same group it was, make it detector again, now check the ips.
