Then open iTunes and turn on Home Sharing.

From Apple's Support:


  
  Open iTunes and make sure you have the latest version.
  Go to File > Home Sharing > Turn on Home Sharing.
  Enter your Apple ID and password. Make sure to use the same Apple ID when you set up Home Sharing on your other devices.
  Repeat these steps on other computers that you want to use with Home Sharing
