I have the latest gen of iTunes and a 4th gen iPod touch. It recognizes my device just fine, and starts the sync all right, but it only gets about 10-15% through the 'backup' phase and quits. This never happened before. With my last version of iTunes, I did have to restart the process a few times, with each succesive instance getting farther through the backup. Now, it just sits, and I have to invoke the task manager to kill iTunes. What could be wrong?

iPod touch, iOS 5.0.1

    Close your iTunes,

    Go to command Prompt -


    (Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".


    (Win XP SP2 n above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt


    In the "Command Prompt" screen, type in


    netsh winsock reset


    Hit "ENTER" key

    Restart your computer.

    If you do get a prompt after restart windows to remap LSP, just click NO.


    Now launch your iTunes, Sync and see if it is working now.


    If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

    You're very welcome.


    Most of the Internet connectivity problems arise out of corrupt Winsock settings. Windows sockets settings may get corrupted due to the installation of a networking software, or perhaps due to Malware infestation. You will be able connect to the Internet, but the packets won't transfer back and forth. "netsh winsock reset" command will reset your Windows TCP/IP to it's default state.

    During your Backup stage, iTunes needs to communicate with Apple's secured server to verify your AppleID and necessary information.  Without smooth connectivity, it just got stuck and no way to proceed further.
