Windows 7 Action Ceenter reports:

Address a problem with Bonjour

Bonjour has stopped working properly.

The name of the file that caused this problem is mDNSResponse.exe.

For information about possible solutions to this problem, go online to the following Knowledge Base (KB) article:

When clicked, the browser opens to the Bonjour Print Services for Windows download page.

One could infer this means "Download and reinstall Bonjour Print Services for Windows." Is that what we are supposed to do?

All messages in the Event Viewer where the source is Bonjour Service are of severity Informational. They alternate between Service Started and Service Stopped(0). My guess is the (0) is the return value.

I am asking here rather than some other stack because the malfunctioning software is a Windows executable authored and controlled by Apple. When an application experiences a problem, it is the application which has the first responsibility for diagnosing and reporting the problem. The operating system is responsible for faithfully executing the services the application requests, but it is unreasonable to expect the operating system to explain to a user why exactly an application ended abnormally. Thus, this is an Apple issue, not a Windows issue.

After reinstallation of Bonjour, the problem was no longer reported. However, that does not mean the reinstallation was fix; it could be that the problem is transient.

  • Hmmm, Apple software on Windows question. I guess the "Apple Software" part defines the fact that you posted it here? – Jason Salaz Jan 17 '11 at 17:49
  • Altough this about Apple software, you might have better luck posting on Super User. – Nathan Greenstein Jan 17 '11 at 18:06

    @VxJaxonxV, I post here because people on the Apple stack are more likely to have experience with Bonjour than people on the SuperUser stack. One of the current top Bonjour questions on SuperUser is "Do I need this software for any reason?" – Thomas L Holaday Jan 17 '11 at 18:14

    @Thomas L Holaday - This is indeed Apple software however, the error itself is probably in some way related to the Windows OS. Did you try re-installing? Apparently Win 7 is much better about permissions however, I saw this a tonne on XP/Vista, and usually the process was not running with the right credentials. Also; are there any entries about it in the event log? – Harv Jan 17 '11 at 18:22
  • Please provide some more info taken from the Event Log of Windows, otherwise this is virtually impossible to diagnose. – Martin Marconcini Jan 17 '11 at 23:58

I cleared the problem on my system by reinstalling Bonjour.
