Error message -15000 from iTunesWindows 7

In some instances, when trying to stream audio from a computer using iTunes® to an AirPlay® device such as the Bowers and Wilkins Zeppelin Air, an error message (-15000) may be displayed in the iTunes window. This inhibits the ability to playback audio, due to certain UDP ports on the system being blocked.

This error is documented within the Apple support knowledgebase regarding AirPlay devices and can be found here.

Before Proceeding

Ensure that both iTunes and your Zeppelin Air firmware have been updated to the latest version.

If you are using a third party firewall (such as Norton™ or McAfee™), the Windows® native firewall is normally disabled. If it isn’t this can be achieved by following the first three steps of this guide and then selecting the ‘Off (not recommended)’ option in the firewall settings.

If after doing this you are still presented with the error message when trying to stream audio from iTunes, please consult the security software vendor for further instructions on adding ‘iTunes’ and ‘Bonjour’ (ports 6001-6003), as exceptions in your firewall settings.
