None of my iDevices can read my iTunes library after an hour of availibility. When I first start iTunes I can read the library, but after about 30 minutes my iPad's and iPhones can no longer access the library. I see it in the shared list, but no access.

Not really improved as I could always stream a movie without issues. Just giving it a longer test.

9 hours so far 🙂

OK 10+ hours and the stream collapsed. Cannot get any computer nor ATV to load the shared library.

I went to close the Matser Itunes and it warned me that 2 users were connected and sharing the library - or even though it would not stream nor load a library on the ATV or laptop it "knew" that they were connected.

As usual a restart of the mater itunes solved the issue.

Are you listening Apple? I have sent a bug report but their silence is deafening.

In fact I've found their support on most issues to be pretty good - not so in this case though.

Not sure about getting it in the news - if this forum (their support form) is not a good place then one wonders what would be.

(sigh)

So finaly digged a bit more how to really disable IPv6 on Windows XP 32 bit running on top of a VMware ESXi hypervisor. Doesn't look VMWare is causing issue. I had no IPv6 under network properties in Windows, but i still typed the following command under DOS prompt to completely uninstall IPv6 on the OS:

netsh int ipv6 uninstall

Started iTune 14 hours ago after using this command + OS restart and this morning iTune responded quickly even after 14 hours of idling !!! First time since a couple of month that iTune respond in the morning.

What the heck is IPv6, and where is it?

I have this problem, and here is my setup.

When I try to access the library with either of my 2 Apple TVs, or the 2 iPhones in the house, or or iPad, it can see the computer but cannot access the library (Apple TVs just have the spinner). if I restart iTunes or turn Home Sharing off then on again, it works fine for everything. If the library is not accessed again for a while (not sure how long) then problem reoccurs.

My iTunes library is running on a Mac Mini which has no power management turned on; it never sleeps nor do the hard disks. All hardware is wired, no wireless involved. IPv6 is turned off on the Mac Mini. This problem has only been occurring in the last month or so, with no change in hardware.

Daniel,

Add one iPad and a drobo my library resides on and you have described my setup exactly.

As for the tech support this is clearly more than they can handle. This is a huge bug and one of those instances where apples tight lipped culture is a pain to deal with.
