SEP 12 Clients keep showing up & dissapearing from the SEPM console
I have a problem with a whole list of clients (all servers , did not check workstations , all having SEP 12 installed) that are not showing up in my SEPM 12 console (searched by username, hostname, OS , IP ...) . I checked the AV locally , on the clients and it showed up as managed , connected to the (right) SEPM , even indicating the folder it belongs to in the console (under troubleshooting) . As soon as I hit the "connect now" button , the last communication date gets updated and the server shows up in the console , with my username associated . All good so far ... glad that the problem was solved ...i went ahead and did the exact same thing on the next client ... the client turned up in SEPM , in the folder it was supposed to ....but at the same time i noticed that the first client i did that on was gone .... went back to it , repeated the action , only to see that the other client was gone ...
So only the last server i perform this action on remains in the console ... thought the problem might be that their are all in user mode ...but when i right click them i get the option to "switch them to user mode" so that means they're already in computer mode ...
Don't know if i provided enough details ... but i really need help with this .
any hint / idea is most appreciated
