With Bonjour for Windows, you can easily network your Windows computer to an existing network or create instant networks of multiple devices without any additional network configuration.
Bonjour, also known as zero-configuration networking, enables automatic discovery of computers, devices, and services on IP networks. Bonjour uses industry standard IP protocols to allow devices to automatically discover each other without the need to enter IP addresses or configure DNS servers.
For Windows 2000, 2003, and XP
