Anyone any ideas on this ? im running 4.5.8 and just checked the usage now, there's 22 active sessions and my LMC reports there's 3 ! the PS4 farm usage reports correctly however, and thats in the same subnet as the AAC server so there's no firewalls inbetween, so not sure whats going on. Strangely though, the CAG itself reports the correct session usage, and that is in a different subnet. My LMC is 4.5.1 which should be fine Andy
