Embodiments are provided for causing a playback device to be automatically added to a secure network for rendering media in synchrony with other devices in the secure network. The playback device may, without any input from a user, transmit a first message indicating that the playback device is available to join the network. Upon receiving the first message, a device already in the secure network may transmit to the playback device a second message indicating security parameters for joining the network. The playback device may then join the secure network accordingly. Embodiments are also provided for causing a playback device to be automatically configured, without any input from a user. Another device in the secure network may receive a configuration table indicating setup information for the playback device, and may subsequently transmit the setup information to the playback device and cause the playback device to be configured accordingly.
