I am using itunes sharing from my desktop to my ipad which works just as it should. The MBP I have along side the ipad does not see the other two devices. I have checked and rechecked all of the sharing settings and I am not behind a firewall. Thanks for the help
The Macbook won't see the iPad, you can only share to an iPad and not from it. Is the Macbook connected to the same network as the desktop and home sharing is 'on' via the same account ?
