Hi Alan, When the iMac sleeps there is no network connectivity. You can put just the display to sleep (ctrl-shift-eject does this). This will turn off the display and conserve power whilst still keeping the iMac turned on and thus the network connection(s).
Or, Perhaps try turning on 'Home Sharing' and see if that helps? Also what happens if you Quit iTunes and Re-launch iTunes?
