Auto-Sync Time Clock

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 to receive incoming packets. Bonjour will configure the Windows firewall appropriately during installation on Windows XP Service Pack 2 and above.

If your version of Bonjour does not include the IE plug-in mentioned above, and you would like this feature, you can download the complete Bonjour for Windows package from Apple's web site by visiting http://www.apple.com/bonjour/ . The current implementation of Bonjour for Windows requires Windows 2000/2003, Windows XP or Windows Vista. Make sure you have the latest Windows Service Pack installed on your computer using Windows Update.

Bonjour is normally placed in a folder called "Bonjour" within the "Program Files" folder. Bonjour modifies registry entries related to Bonjour's internal configuration and operation. In the list of MS Windows startup services, Bonjour runs as the name mDNSResponder.exe, consuming almost a full megabyte of memory. Communications across the network take place over UDP port 5353; this may require reconfiguring some personal or corporate firewalls that can block Bonjour packets. A full installation of Bonjour for Windows will include a plug-in for Internet Explorer, a printer wizard and the network communication services.

Some Virtual Private Network (VPN) clients are configured so that local network services are unavailable to a computer when VPN software is active and connected. In such a case, no local Zeroconf services are available to Bonjour or any other Zeroconf implementation. If you find that you can no longer discover network services or print to Bonjour shared printers, try logging out of VPN.

NOTE: If Bonjour is not desired or available for your network use, it is recommended to use the Auto-Sync Utility that came with your clock to perform the Zeroconf function for discovery.
