Bonjour? Au Revoir.
Lets say you’re using Autoruns one day and the following conditions arise:
- You notice that the Bonjour service has somehow made its way onto your system (usually courtesy of iTunes or Adobe Creative Suite).
- You find yourself incensed that some dodgy and largely unnecessary Apple networking software has installed itself without asking.
- You discover that the Bonjour service in inexplicably absent from Add/Remove Programs, thus further infuriating you over the stealth nature of the install.
Under these conditions, DON’T do what I did and simply delete the references to mDNSResponder.exe and mdnsNSP.dll using Autoruns. All that will get you is a machine that, after its next reboot, can no longer resolve DNS addresses correctly, leading to a short sharp visit to System Restore. Instead, here’s how to remove Bonjour without tanking your network connectivity:
- Run the following via Start -> Run:
"C:\Program Files\Bonjour\mDNSResponder.exe" -remove
- Go to the C:\Program Files\Bonjour folder (or C:\Program Files (x86)\Bonjour if you have ended up with a 32-bit version of Bonjour on a 64-bit OS)
- Rename the mdnsNSP.dll to something else (it doesn’t matter what, my preference is for mdnsNSP.turd)
- Delete the aforementioned Bonjour folder from Program Files.
