Itunes unable to locate zeppelin remote speakers

Question

We have just purchased a wireless zeppelin speaker and my itunes is unable to locate devices, I have followed instructions within preferences set up - how do I access devices menu to add a new device?

Answer 1

The exclamation marks (and the accompanying note) inidicate the files aren't located where iTunes expects them to be.
This most often happens when the files have been deleted or moved to a different location than where iTunes expects them to be.
If the files are still on your computer but have been moved, the best solution is to get them back where they were in the first place. iTunes will be able to find them again - happy ending.
It can also happen if the files have been renamed in which case changing the name back to what it was in the first place is the way to go.
Sometimes though, it seems iTunes loses track of files for no apparent reason. In that case, other than telling iTunes where they are on a one by one basis, your only other option is to start with a new iTunes library. Regrettably, this method will lose your playlists and related information (Ratings, Play Counts, Dates Last Played, etc.).
If that's not a deal-breaker for you, delete the current entries in your Library by highlighting them - iTunes Edit menu > Select All - and then right-clicking > Delete . You are removing the entries from your Library but keeping the files themselves in your iTunes Music folder, or wheresoever they happen to be stored.
You can then add them back into your Library by selecting the iTunes Music folder in Windows Explorer and dragging it into the Library entry in the iTunes Source List (left-hand column). Reference this article in the Apple Knowledge Base.
