HowTo: Resolve error -3256 in iTunes

I have good news for all the annoyed iTunes users out there with error -3256 popping up all the time. Do you also belong to the people being prevented from streaming music over the network to your AirPort Express while maybe syncing with other devices like Apple TV?

For all the ones who are fed up with it I have a solution that might work (specifically for Mac OS X Leopard):

1. Go to System Preferences. Choose Network, then Advanced…

2. Click on the menu tab TCP/IP.

3. In the drop down list Configure ipv6 choose Off.

Also, make sure that your firewall does not block any incoming connections. If the error persists, turn it off, i.e. activate Allow all incoming connections.

Please feel free to report back here to share your success with us. Maybe you can deliver other good solutions not mentioned here.

Please note: You take full responsibility for your actions on your computer. I can never be held responsible for any damages caused by my tutorials. Errors excepted!

Problems in iTunes 7.6

Some weird things happened after updating to the new iTunes version, which was released at the Macworld keynote. I’ve never experienced this issue, but now when playing songs in my library over the AirPort Express station, which is connected to the Airport Extreme, iTunes suddenly interrupts and stops playing them. What is more, during that time, I cannot connect to the internet anymore, even with other computers connected to the network. The only reason for this problem I can see at the time is the new update of iTunes because with the earlier version it worked flawlessly. It’s getting really annoying…
Now I want to ask you, bloggers and visitors of my page: Do you also have the above described or similar problems? If yes, do you know something like a work-around? Any comments on the topic are highly appreciated.

UPDATE OF JANUARY 27:

Strange as it seems, after a reinstall of iTunes 7.6 (I tried to install 7.5 again with no luck) it now works without any problems (no interruptions while playing). This is the situation for the German version of iTunes running in Switzerland. I will keep you updated in case I encounter new problems.
