Windows 7: How-To: Remove Bonjour and fix networking issues

How-To: Remove Bonjour and fix networking issues

I just went crazy as how strange issues my computer produced after I installed a program that uses Bonjour service by Apple (usually Adobe CS3 or iTunes). I tried to remove it following the posts I found around the net, but it just totally broke my system. So after a reinstall and some struggle I think I found what to do in what sequence to get Bonjour removed and the networking system fixed.

Some of the issues which happened frequently for me were:
  • No internet connection if you turn on your computer until you manually disable and enable your adapter.
  • Strange behaviour during internet browsing: you have to refresh pages sometimes as they just not load for the first time, or click on a link twice as nothing happens for the first time.
  • You have to connect multiple times to a FTP server, as nothing is happening for the first time.
First you should download two programs and save or print this guide as your internet connection can go down after the first restart.

  1. Download and run TurnOffBonjour.exe
  2. Rename Program Files\Bonjour folder to Bonjour.bak
  3. Download and run LSPFix.exe from You just need to click "Finish" and "OK"
  4. Restart your computer
  5. Write "netsh winsock reset" in the Start Menu/Run.. prompt. You might need to do it as admin.
  6. Restart your computer again.
Now everything should work as it was originally, before Apple's evil Bonjour service turned everything upside down. You can delete or leave the Bonjour.bak folder if you like.

This seems a lot simpler. Did this solution not work? I'm trying to understand which method messed up your system.

RogerR, that method is the same as what TurnOffBonjour does in one click.

Almost all the guides say just how to remove Bonjour, but you need to fix your Winsock, as it doesn't fixed anything, just removed the service. You must edit the registry or run LSPFix. And you must reset winsock after everything is done.

reghakr, the same, I don't know if that util does anything with winsock.

For me only the complete way worked, first remove, then fix winsock.
