If you are having problems getting iTunes to recognize an iPod, the first step ISN'T to reinstall iTunes, or even restart the computer. I've seen a lot of people suggest this, but there is a much simpler method that in my experience works 90% of the time. All you may need to do is restart the Apple Mobile Device service. This service manages how devices connect to iTunes. It doesn't always run properly and sometimes needs a little kick to get it going. Here's how (Windows only) Windows XP: Open the Start Menu go to 'Administrative tools > Services' (If that isn't there, see below). Find 'Apple Mobile Device', right-click on it and click 'Restart'. Wait for it to restart and then close the Services window. Re-connect the iPod and see if it works now. Windows Vista/7: Open the Start Menu and type "Services" and the click on it in the results (If it isn't there, see below). Find 'Apple Mobile Device', right-click on it and click 'Restart'. Wait for it to restart and then close the Services window. Re-connect the iPod and see if it works now. If you can't find Administrative tools or Services: Open the Start Menu and click/type 'Run'. Type 'mmc' and click 'OK'. If you get a UAC prompt, click Yes/OK. In the console, go 'File > Add/Remove Snap-in...'. Find 'Services' and click 'Add'. Choose 'Local Computer' and click 'Finish' then 'OK'. Click on 'Services (Local)' in the tree and then follow the instructions above. You don't need to save the console when finished. If all else fails, you will probably need to reinstall iTunes, sorry.
