Why do you think the 5.0.0.48 is being discussed here? It's 5.0.2.5 now. And why do you want both machines to run BI as service? I understand the main one ("server") with the cameras should run as service but the "client" machine running as service will increase the CPU utilization of the "server" machine keeping the remote connection active even when not needed.I would try updating both machines to current version...lot of changes since 5.0.0.48, also make sure both machines run BI as service.
