I installed Meridian Device Manager from the given link. When I open it, all I see listed is ControlPC. I only have one network at home, and the Rock and QNAP with music stored on it appear in Windows Network. The network router is an Apple AirPort with an unmanaged switch and AirPort bridge.

Cheers, Ian
