I have setup a single server as an unmanaged detector. It is on the same subnet as a machine I have uninstalled SEP 12 from. NTP is enabled on the server. It is not detecting the client on the network without SEP installed on it, though.
The client originally had SEP 12 installed on it. I uninstalled it and then ran CleanWipe on it just to make sure. The client was turned off overnight as I read on another discussion that the machine needed to be off for a while. When I came in this morning and powered it on it still did not get detected by the unmanaged detector.
The server acting as the unmanaged detector has NTP enabled on it. It originally did not have NTP enabled, but I enabled it yesterday afternoon via a command I ran on it through SEPM. When logging in on the server it shows that NTP is active and working.
I did not reboot the server after I enabled NTP on it. I have seen nothing stating that needs to happen though. It is just not detecting the clients without SEP installed on them. Any thoughts?
