Recently we updated from SEP 11 where we had the use of the Find Unmanaged Computers facility coveniently located under Clients. Now with SEP 12 we have to use the enable as unmanaged detector feature so we have to view the results through daily reports.
However, I know that SEP 11 had issues with false postives when using the Find Unmanaged feature but now with SEP 12's Unmanaged Detector feature we seem to be having to do even more work to check the results!
We use DHCP for our clients, when looking at the unmanaged machines report we will ping the IP addresses and if we get a response we will then do a nbtstat -a command to resolve the machine name so that we can check it in the SEPM console. However, the problem I am finding is that by doing that we are getting false positives i.e. when checking the machine name it SEP it is actually managed. But, the most concerning thing is that the MAC addresses that SEP comes back with, do not seem to match any known machines on our system and do not match the MAC of the machine name that resolves when performing the nbtstat through CMD.
Anyone else having problems with detecting clients without SEP or are unmanaged?
