Ok - so I have already read the manual - which sadly is no help at all in this case.
Mapping a network drive is one way to access file from the PC, but for that I would not need an iTunes server - it is just a network share. And no way to access it from am iPad, iPhone…
Anyone having successfully streamed music to an iPhone, iPad using the iTunes server?
I fear it is not possible - but why then implement an iTunes server?
