I had around 15 clients in a unique group in SEPM, suddenly they disappeared from the list. The clients still have the SEP installed and they keep working normally, but they don’t receive the latest virus definitions from the server.
I have uninstalled SEP in some clients and when I look for them in the SEPM I find them as Unmanaged Clients, but when I install the client software on them, they don’t appear in any group (not even in temporary group). I have no problems on my network (I ping the clients and they respond constantly).
What can I do? Best regards…
