What is Bonjour and what is it used for in Creative Suite products?

When you install an Adobe Creative Suite CS3 or a Creative Suite CS3 point product on Windows, Apple's Bonjour for Windows is installed and registered as a Windows service on the machine.

When you install an Adobe Creative Suite CS4 or Creative Suite CS4 point product, Bonjour is not installed as a separate Windows service . The same networking technology is still used in Creative Suite CS4 and Creative Suite CS4 products. It is implemented internally instead of installing and registering a Windows service.

Bonjour is an open source implementation of zero-configuration networking software. It is used to dynamically discover Version Cue servers on the local network so you do not need to connect to them manually by name or IP address.

For automatic discovery of Version Cue servers on the local network to function correctly, you must allow Bonjour access to the internet through your firewall. Bonjour checks to see whether the DNS server configured on your computer supports service discovery. No data is transmitted to Adobe. Bonjour connects to no other servers than your machine's pre-configured DNS server. Bonjour also sends network packets to and receives them from a multicast IP address on the local network (244.0.0.251) once every thirty minutes. This address is reserved for multicast traffic on a local network and such network packets never leave the local network.

Identifying the Bonjour service in the Windows Services control panel (CS3 only)

When installed by Creative Suite CS3 applications, the name used by Bonjour for Windows in the Services control panel is:

##Id_String2.6844F930_1628_4223_B5CC_5BB94B879762##

To correct the service's name, open a Windows command prompt and type the following two commands. Each command needs to be executed individually -- type in the command and hit enter to execute it, then wait till you are back at a prompt (C:/>) :

  1. "C:\Program Files\Bonjour\mDNSResponder.exe" -remove
  2. "C:\Program Files\Bonjour\mDNSResponder.exe" -install

The service will now be displayed with the correct name in the Services control panel.

The Adobe Captivate movie below illustrates how to correct the Bonjour name in the Services Control Panel (CS3 only).

 

Removing Bonjour for Windows (CS3 only)

To remove Bonjour:

  1. Open a Windows command prompt and type the following command:

    "C:\Program Files\Bonjour\mDNSResponder.exe" -remove
  2. Navigate to the following folder in Windows Explorer: C:\Program Files\Bonjour
  3. Rename the mdnsNSP.dll file in that folder to mdnsNSP.old
  4. Restart your computer
  5. Delete the the Program Files\Bonjour folder

Note: Removing Bonjour prevents Version Cue clients (Photoshop, Illustrator, InDesign, Flash, Bridge) from automatically discovering Version Cue Servers and Version Cue projects in your local network. You will need to connect manually using Connect to Server and the URL or IP address of the machine running Version Cue Server instead.
