  1. Thanks Madhuparna, I appreciate you sharing. I have all those settings correct, but I still get the error in event viewer. Any second thoughts?

  2. Maybe you can help.
    Win 10 PC. iTunes cannot enable sharing unless Bonjour Service is running. I have set it automatically and automatically delayed. After I restart, it comes up running but on a second restart it comes up disabled. This is driving me crazy!
