Error, this module is blocked from loading into Local Security Authority Bonjour/mdnsNSP.dll

Question

Usually once per today, while doing nothing, I get the pop up that module is blocked from loading into LSA, and its a folder Bonjour/mdnsNSP.dll.

Does anyone know how to fix this? What is happening. Thanks

Answer 1

winget upgrade bonjour...

No available upgrade found.

No newer package versions are available from the configured sources.

pop-up error still persists.

I have the issue but have neither itunes or anything apple related installed

Answer 3

I started getting this same error message after upgrading to Windows 11 24h2.

I started a powershell prompt (admin) and used winget to upgrade bonjour service.

'winget upgrade bonjour'

It upgraded me from 3.0.0 to 3.1.0.1

The error seems to have gone away.

I am occasionally getting this error on my new Windows 11 24H2 desktop computer. I do not have iTunes or anything of that sort. But I did learn the hard way on my old Windows 10 box a few years ago that Bonjour is needed for my computer and printers to find each other on the LAN.

I did not explicitly install Bonjour. It must have happened when I set up the Epson printer on the PC.

Network printing has been working fine in spite of the error. But I decided to try your powershell command. I had to log into the computer with my Microsoft account to make it work. (I normally use local accounts.) I got the update to 3.1.0.1.
