Sharing only works if the desktop PC (always on) is also running iTunes.
When I'm down the garden in the workshop, using the Windows 7 laptop that lives there, I can only play music on iTunes if the (Win 7) desktop in the study upstairs in the house (always on) is also running iTunes. Normally it won't be. Is there a way for iTunes on the laptop (on the home network) to access the iTunes library on the desktop without me having to go back to the house, unlock, go upstairs, and start iTunes on the desktop?
At the moment, I don't bother - I just run Windows Media Player which plays the iTunes music library fine, but not the playlists.
There's no spare space on the laptop to download the music library to that.
