Bonjour causes 2 network connections and no access

For some reason the Bonjour installed with CS2/CS3 can have the unintended effect of making your network connection look like two network connections and actually disconnecting you from the network.

I’m not clear on how it works, but it’s trying to help you out by looking for machines around you running Version Cue.  However, somehow it ends up making your default gateway 0.0.0.0 which doesn’t work at all.  If this happens to you, you can remove Bonjour pretty simply if you don’t need it.

Removing Bonjour for Windows (CS3 only)

To remove Bonjour:

  • Open a Windows command prompt and type the following command:
  • “C:\Program Files\Bonjour\mDNSResponder.exe” -remove
    • on 64-bit systems this may be Program Files (x86)
  • Navigate to the following folder in Windows Explorer: C:\Program Files\Bonjour
  • Rename the mdnsNSP.dll file in that folder to mdnsNSP.old
  • Restart your computer
  • Delete the the Program Files\Bonjour folder
