Apple TV falling off iTunes

I have the similar problem. After several failed attempts, I was able to get homesharing working by power sequence the modem, router, computer (reboot the router alone did not work for me). After a day or so, I lost home sharing ability, Power sequencing again, it did not work. I went into Norton firewall, to change the setting allowing share window files, it worked again, except only once. Now home sharing does not work even with firewall disabled.

When select home sharing on Apple TV, it asked me to turn on itune home sharing using my specific apple ID, which has been turned on, and the Apple Id in itune and Apple TV were identical.

Two problems: 1, How to get back Home Sharing? 2. How to keep it without losing it?

I have had the same frustrations for months. Then I read a suggestion and tried it and it worked, at least for me. Here is what you do.

Go to Control Panel

Then click Network and Internet

Then Network Sharing Center

Under Connections, click your internet connection.

In the pop up box click on "properties" and when the box pops up, say yes.

Then uncheck Internet Protocol Version 6 and click the okay box.

After I did that mine started working and has worked even after turning off itunes and getting back in.

I hope this works for you.

I tried and it worked for me too. I spent so much time on this and it appears to be solved. After turned off and on itune, the connection stayed. If no posting from me then this solution works for me. Just wonder what side effects it might have by turning off IPV6.

Thank you very much Mg6035 for sharing.

It works for me. Disabled ipv6 stays disabled even after reboot. I consider this problem solved for me.

I rebooted and it stayed disabled for me too so hopefully that won't be a problem in the future.
