Installation and Operation Guide

4-2 TS-3000i Web Clock Installation & Operation Guide
Bonjour, formerly Rendezvous, is Apple Inc.'s trade name for its
implementation of Zeroconf, a service discovery protocol. Bonjour
locates devices such as the TS-3000i Web Clock, printers, copiers, and
other computers, with the services that those devices offer on a local
network using multicast Domain Name System service records. The
software is built into Apple's Mac OS X operating system from version
10.2 onwards, and can be installed onto computers using Microsoft
Windows operating systems.
Bonjour is a networking protocol that sends and receives network
packets on User Datagram Protocol (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 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.
