What is MDNSResponder.exe or Bonjour?
The process MDNSResponder.exe is related to Bonjour, Apple's Zero Configuration Networking application, often automatically installed by iTunes. Wondering how iTunes can communicate with clients on the same local network? Bonjour is what you need to pay attention to.
Not using iTunes? iTunes isn't the only way to install Bonjour on your computer. It's also bundled with a range of other software like Pidgin, Skype, and Safari, used to connect clients within the same network.
MDNSResponder.exe or Bonjour is deployed as a Windows service, and you can see it in the Services console (just type services.msc in the Start Menu search box). You can stop the process here anytime.
The problem here is that MDNSResponder.exe or Bonjour doesn't appear in the Add/Remove Programs window, so you can't uninstall it through the usual methods. However, you can still remove MDNSResponder.exe, but it will limit some functions of applications relying on this process.
Important Note: If you're using iTunes to share libraries or any other features dependent on it, you're not allowed to uninstall Bonjour.
How to uninstall Bonjour?
Firstly, it's important to note that you can disable Bonjour without uninstalling the application. Simply access the Services window, double-click on the service, and change the Startup type to Disabled.
If you don't want to break anything, this is the best solution for you. If any issues arise, you can always reactivate the service.
How to uninstall Bonjour
Unlike uninstalling software, if you're sure you want to uninstall Bonjour, the steps are quite simple. Just open Command Prompt with Admin privileges (type cmd into the Search box, right-click on the result, and select Run as Administrator), then navigate to the installation directory using the command below:
Program FilesBonjour
If you are using Vista or Windows 7 64-bit version, you need to access the Program Files (x86) directory instead. Enter the command below to view options:
mDNSResponder.exe /?
The next step now is to uninstall Bonjour using the command below:
mDNSResponder.exe -remove
You will receive a notification stating that the service has been deleted (note that you must open Command Prompt with Admin privileges).
If you want to disable the DLL file in the directory, you do so by renaming the file to a different name:
ren mdnsNSP.dll mdnsNSP.blah
Alternatively, you can delete the entire directory if you wish.
How to reactivate Bonjour?
To reinstall the Bonjour service, use the command below:
mDNSResponder.exe -install
