I just had the same problem that started a few weeks ago. I just fixed it this morning. ( I'm using Windows XPSP2). I went to Start, in the Run box, typed in msconfig, went to the StartUp tab, and looked for ITunes Helper. The box somehow became unchecked, don't know why or how. Rechecked it, restarted computer, and it now automatically connects to Itunes. Hope this helps you.
