Bonjour service errors on Windows 11

Bonjour service errors are quite common, and can be seen in the application log of events viewer in Windows 11. Generally, you get the Bonjour service errors at the time of startup of Windows 11 computer. Generally, we treat Bonjour service as an interface point for Apple devices and iTunes on the computer.

What is the Bonjour service error on Windows 11?


Bonjour service provides seamless interface between Apple devices and Windows 11 computer. If you have an Apple TV, it will work with Windows 11 through the Bonjour Service. On a similar service, if you have a working copy of Apple iTunes on a Windows 11 computer, Bonjour service will act as a gateway between Apple and Windows 11 operating system.

Bonjour service may generate different type of errors. These could be on account of failure of the name resolution services to provide a unique name to the Bonjour service. Or, the errors could be on account of inability of the Bonjour services to start properly. The error resolution would largely depend on the type of error you see in the application log of the event viewer.

In some cases you may not be making use of any Apple device through your Windows 11 computer. In such cases it is better to disable the Bonjour service. If you are not using the service, it is better to stop it and disable it.

Bonjour service works on the basis of TCP/IP networking. So, a working state of Bonjour service needs a working TCP/IP networking stack on your Windows 11 computer. If there is any problem in the TCP/IP stack, Bonjour service will generate an error. On a similar basis, the Bonjour service needs to work with the name resolution scheme on the computer. The Bonjour service assumes a name for rendering the service. It, therefore, needs a proper name to be identified on the network. The name sequence is generally configured to work on SYSTEM-02. If it is unable to get that name, it tries to assume names in the sequence such as SYSTEM-03 and so on.

If we were to state a summary of requirements of proper working of the Bonjour service on Windows 11:

  • we need a working TCP/IP networking stack on Windows 11 computer
  • we need the name resolution services to provide a unique name to the Bonjour service.

Most Bonjour service errors will correspond to either of these 2 reasons. So, an error in the application logs of the events viewer implies that either there is an issue with the TCP/IP dependency services or the name resolution has failed for the Bonjour service.

For example, the error below suggests that the Bonjour service was unable to assume a unique name on the network for rendering the service:

Error – mDNSCoreReceiveResponse: Resetting to Probing: 4 SYSTEM-02.local. Addr 192.168.39.239

Error details –

mDNSCoreReceiveResponse: Resetting to Probing: 4 SYSTEM-02.local. Addr 192.168.39.239

Upon digging the details of this error, it became clear that the Bonjour service failed in securing a unique name from the computer’s name resolution service. ‘Resetting to probing’ means that the Bonjour service is trying to probe or search for a name for itself. The cause of the error is the removal of QTTask and iTunesHelper from the computer’s startup through msconfig command. To resolve the error, you will need to reinstall the iTunesHelper on your computer and let it run at startup.
