Xcode 4.2 is beta software, which usually means you cannot archive your app for ad-hoc distribution from it.
You need to use Xcode 4.0.2 or Xcode 3 to archive your app for ad-hoc distribution.

If that doesn't help, make sure you have the provision profile you used to codesign the app with dragged into iTunes!
