make sure you have the latest Service Pack installed for your computer. Firewall requirements The Bonjour networking protocol sends and receives network packets on UDP port 5353. If you have a "personal firewall" enabled‚ you will need to ensure that UDP port 5353 is open for Bonjour to work correctly. Certain firewalls will only partially block Bonjour packets‚ so if you experience intermittent behavior‚ check the firewall settings and verify that Bonjour is listed as an exception and is allowed
