One of the most useful elements of Apple’s “digital hub,” at least for media like music and movies, is Home Sharing. This feature allows you to share your content across your local network to computers, iOS devices, and Apple TVs. However, it is not without its problems.

A correspondent recently had a problem with Home Sharing, and it was quite difficult to troubleshoot.
