The Bonjour service has been disabled message in iPHONE

Hi All,
Recently from a day or so I am getting the below error message. Does anyone know what this is about and how can I get rid of this:
The Bonjour service has been disabled. Bonjour is required for sharing music with others, playing music through Airplay speakers, connecting to Apple TV, and using the iPhone and iPod touch Remote. Re-enable the service in Control Panel -> Administrative Tools -> Services.
Regards.
