I use a Mac Mini as my home media iTunes client, serving two Apple TV units plus being hooked up to a TV itself. Most of the time, everything work perfectly. Most of the time. However, to administer the server and the library, I use my MacBook or the iMac to remote in. It seems that often when I do that, even well after that connection is closed, Home Sharing no longer works, and I'm forced to re-start iTunes (or reboot the Mini) to get it going again. Anyone familiar with this or can offer advice on how to prevent it?
