Bonjour services erratic or missing, mDNSResponder quitting on boot

I've searched the forum, and found that several users have had trouble after the update to 10.5.5. I think my problems stem from mDNSResponder not launching correctly. What happens is that my MacBook and my PowerMac G4 no longer see any Bonjour related services on the network. A printer connected to an AP express won't show up, Airport Utility can not see the AP express or the Time Capsule. +"File > Configure other..."+ will see the units, so the problem is down to Bonjour. Same for the printer, it works on the MacBook where it's already installed. On the G4 it's missing all together. Shared folders will not show up "bonjour-wise", but mounting them manually by IP-address works. This line appears frequently in system.log:
22.11.08 22.31.16 com.apple.launchd[1] (com.apple.mDNSResponder[26]) Exited abnormally: Segmentation fault
In short, my network is functioning as it should, but none of the Bonjour-enabled services advertising across the network register on the Macs. The network consists of a single 192.168.1.0/24 subnet, a Time Capsule as the main router, an AP express connected via WDS and three connected computers, two Macs and a Vista PC. And all Bonjour services work on the PC! And it all worked just fine a few weeks ago, prior to the update.
Please help...

Thanks Snoop! It just didn't spring to mind late last night... There are at least 20 entries from the last day, and they seem to be quite identical. The entries are about 10 minutes apart. Here's the crash log:

Slew of Problems with iTunes--Bonjour Service, Ipod Touch Recognition, iTunes Store Connectivity

As per the title, the problems are getting quite serious and annoying.
I have an issue with the Bonjour service not being recognized (mDNSresponder.exe doesn't appear to be running) and consequently sharing not working, an inability to connect to the iTunes store (as shown in the above diagnostic report), and an inability for iTunes or my laptop to recognize the iPod Touch. On any other PC here, it's perfectly fine.

As you can see, there are many problems here. Quicktime is apprently unavailable, when it's installed. iTunes doesn't recognize me as an administrator, when the account is indeed an admin (and can perform administrative actions).
Connection to the iTunes store is unsuccessful, when iTunes is enabled in the windows firewall. All the services iTunes needs to run, are running successfully. The sole exception being Bonjour, which iTunes doesn't seem to realize is running. I've verified the service to be running, and have restarted it. Additionally, mDNSresponder.exe is not running under task manager. Manually starting it from Bonjour's file directory doesn't work, either. I've changed my "hosts" file, and still no luck. I've also changed a couple of Internet Explorer internet properties, and the unsuccessful connectivity doesn't change. I've reinstalled the whole line of Apple software, without a change in results. Reboots are just as unsuccessful.
Ultimately, my problem is neither iTunes nor Windows recognizes my iPod Touch, whereas my old Nano used to work fine. On other computers, iTunes is fine. The problem is on this one, and whether it's an Apple or Windows problem, I don't know. Hopefully someone here can help me out, as I would be immensely appreciative.

One step forward?
I'd like to doublecheck something you mentioned earlier:
I've verified the service to be running, and have restarted it. Additionally, mDNSresponder.exe is not running under task manager.
When you were in the processes tab, did you have "Show processes from all users" checked, as per the following screenshot? (mDNSresponder.exe runs under SYSTEM, so you don't see it in there unless that box is checked.)

Bonjour services stop

For some reason, my 2010 Mac Mini stops advertising all of its Bonjour services. Everything works upon a fresh boot, but it all disappears after a few hours.
I can't seem to find anything in Console that might help me find out why... or perhaps I'm not sure what I'm looking for. It's making connecting to my Mac Mini from my other computers irritating and difficult... and it's important that I fix this issue, as my Mac Mini runs OS X Server and a Plex Media Server.
I've already tried doing a reinstall of OS X, but that didn't fix the issue. I haven't done a fresh install yet, though... Hoping it doesn't come to that.
The Mac Mini is running OS X 10.10.3, but the issue has been around since 10.10.2, I believe.
One other issue... and I'm not sure if it's related, but the MAC address of the Mac Mini's ethernet seemingly changed around the same time. I'm not sure how that's even possible... but I had to change my router's DHCP settings to match.

That's funny. That's the exact opposite of my installation problem. Bonjour isn't able to start after stopping in my case.
Wish i could help, but i'm at a loss myself and waiting for apple/my telecom company to sort out some proper support

Bonjour service is running, but still trouble

Hey guys,
today i want to test Remote for iTunes DJ with my iPod touch.
But I wasnt able to establish a connection between my iPod and iTunes. After a bit of research, try an error, I figured out, that the Problem must be Bonjour. So I uninstall it and reinstalled it.
Rebooted...
Hopefully waited. It fails.
The Bonjour service on my Windows XP SP3 machine ist running, and mDNSResponder is also started.
If I want to start the Bonjour-Printer Assistant, it tells me:
"Bonjour Service not available" I surprised. It ist running!
And in the settings of iTunes, it is told me to avtivate Bonjour.
I searched a lot in Google, but didn't find an answer. Maybe Someone can helb me here
Thank you

Okay, next experiment. We're going to try uninstalling and reinstalling BonJour again. But this time we'll take a few additional explicit precations.
Download and save a fresh copy of the BonJour installer to your hard drive. (Don't do the install on line, and don't start the install just yet:
http://support.apple.com/kb/DL999
Quit iTunes, QuickTime and/or Safari if any of those application are open.
Now head into your Add or Remove Programs control panel. Uninstall BonJour.
Next, we'll clear away any leftover BonJour program files and folder.
Go "Start > My Computer".
In "My Computer", open "Local Disk C:" or whichever drive your *program files* are installed on.
Open the "Program files" folder.
Right-click on the "BonJour" folder (if it still exists) and select "delete".
Go back into Local disk C: or whichever drive your *operating system* files are installed on.
Open the "Windows" folder.
Open the "system32" folder.
Right-click on the dnssd.dll file (if it still exists) and select "delete".
Right-click on the dns-sd.exe file (if it still exists) and select "delete".
Empty your recycle bin and restart the PC.
After the PC restarts, do not launch any applications. Disconnect from your network and/or the internet. Now switch off all your security software (firewall, antivirus, antispyware).
Now start the BonJour reinstall by doubleclicking on the BonJourSetup.exe file you downloaded earlier.
Reenable all security software prior to reconnecting to your network and/or the internet.
Did the BonJour reinstall seem to go through okay? If so, do do you still get the iTunes trouble with the fresh copy of BonJour in place?

Bonjour Service disabled

I have successfully installed iTunes (newest version) and Bonjour Service. When I go to Preferences/Sharing it says
"Bonjour service has been disabled. Bonjour is required to share muisc with other users. Please re-enable the service to use this feature."
When I check services it shows Bonjour as running. What next?????

As a Trend Micro user, I confirm that I had the same problem and it was solved the way indicated by MarcDigsApples (thanks !). But ...
1/ As explained in the Bonjour documentation, I previously opened UDP 5353 in/out for C:\Program Files\Bonjour\mDNSResponder.exe in the firewall rules : no effect. I opened all ports for that program : no effect (it is in this last state yet).
2/ It was MANDATORY to stop firewall AND antivirus AND to RESTART the PC (just stopping them, or quitting Trend Micro, and then trying to restart Bonjour service was not enough - even just quitting windows session was not enough).
3/ At one occasion, I directly launched C:\Program Files\Bonjour\mDNSResponder.exe : it opened an empty DOS window for a few seconds, and maybe it has done something usefull - because further retries just quickly opened end close this DOS window). I don't remember if Bonjour Service was stopped or not at the time I tried this.
I hope this will be helpfull to Robert with his McAfee suite.

Apple TV 3 doesn't start Bonjour services after sleep since firmware upgraded to 6.0.2 (6646.81.1 build)

I have upgraded my AppleTV 3 to firmware 6.0.2 for five weeks but always getting problem in Airplay my ipad2 and wired iMac to Apple TV3. Before that, the Apple TV3 in firmware 5.0 was fantastic in everything. Now, the all-time-sympton of my Apple TV3 waking up from sleep is:
1) iPad2 in IOS6..1.3 can't find any airplay icon, same as my new iPhone 5s
2) The wired iMac can't connect to AppleTV3 through Airplay, neither from Maverick's airplay icon nor from iTune's airplay icon.
3) Further than that, the home sharing from AppleTV3 is found to be disconnected from iTune in iMac
My port-scan towards ApplTV3 at this scenario is found all the Bonjour services are missing, including:
* Remote Audio Output (port 5000)
* _airplay (port 7000)
* _touch-able (port 3689)
* Sleep Proxy Server (port 57206)
* _appletv-v2 (port 3689)
My walk around at the moment is to restart AppleTV3, then all the Bonjour services come back and airplay, home sharing work again. However, this requires me to restart the box everytime I bring up the box from sleep. That means I have to turn on TV... quite fustrated.
I'm wondering if there is any similar problem encounted and any fix. Well, I can't find any formal description from Apple but their trouble-shooting document keeps saying to "restart Apple TV" as last resort.
Tks in advance!

I finally found the like-symptom causing the issue of missing airplay services on ATV box.
Well, I have one airport express installed in my study room, which connects to the same LAN as ATV3 in living room. Today, I reset airport express to factory setting and reconfigured everything on AirportExpress, including its SSiD, wifi network key and device password. All of a sudden, my iPad, iPhone, iMac lost their airplay connection to ATV3. Port scanning found no airplay services on ATV3 box. It needed box restart to bring up airplay as my earlier walk around solution. I still performed reset -> restore for a "permanent fix".
That said we might have airplay icon disappeared again if there were more than one airplay device on the same LAN that would interfere to each other. Working on one airplay device from ground start would cause airplay service of another box malfunction.
My experience showed this twice. The first was happened when I put an airport express on the same LAN and I posted a thread here for help. The second was in this morning when i reset airport express to factory setting

Cannot install itunes 9.2 - bonjour service failed to start

Like in many of the other topics, i am unable to install itunes 9.2 on my computer.
I have checked (and edited if needed) exceptions in firewall etc. I have disabled said security as well. I have even uninstalled all AV.
I have tried the registry changes to grant the bonjour service full priviledges.
I have tried giving the bonjour service administrator rights in the service itself.
I have tried retrying at the error dialog extensively (although i did not put much hope into this one).
I have tried installing airport for windows, which temporarily seemed to get bonjour working, but again it died during itunes 9.2 installation with the same error.
Edit:
I have also (almost obvious) tried to uninstall and reinstall itunes/quicktime/bonjour many times, both in my standard startup setup as well as in msconfig'ed startups enabling only specifics to said programs.
Edit end
The exact error from the event viewer=>Windows Logs=>System is as follows:
The Bonjour Service service terminated with a service-specific error 6 (0x6).
Now, i would very much like this to be fixed as soon as possible (as i'm sure the rest of the users would as well), so i can actually use my iphone for music i already own, manage it and so on and so forth.
I have already spent more than 8 hours on this specific problem since yesterday, which is quite frankly ridiculous. Especially in the context of apple products, which in the past prided themself on being extremely stable and userfriendly unlike most other platforms. I do realize that this does not apply in the same sense regarding the crossover between platforms, but as far as i can tell this problem is an old injury attested by many people on many versions of itunes (and other software) in relation to bonjour.
Edit:
I am running 64bit (and ofcourse using the 64bit installers)

Update:
Well, i called my telecom company and spoke with the same guy i spoke with earlier. He found a technician, but unfortunately he had no ideas for a solution. Instead i was told to reformat.
Now, as i have quite a lot of stuff on my computer which i should back up but haven't yet, this is a very unappealing option to me. Also, from reading these forums there have been several examples of the installer failing in one way or the other even on fresh systems. And lastly, just because a piece of software works on one computer but not on another it doesn't mean i should reformat.
Now, if i had been told the error 6 (0x6) meant something i couldn't rectify without doing a complete reinstall, then i would probably have been ok with it. So that's what i told the supporter. He however had been told by his boss to tell me off with that.
So instead i asked to speak with his boss. We then spoke a little backwards and forwards about support responsibility, when it is ok to ask for a reformat and so on and so forth. I tried to tell him that it was clear to me that it wasn't really their responsibility (as it's a software problem unrelated to the iphone itself), but that it couldn't be my responsibility either to make that clear for apple.
So after a while i was put on hold for a good 10-20 minutes. After which he told me that he understood my situation and that he would talk to their chief of the supporting division (or something) as that guy is in charge of the contact with apple.
So all in all i didn't get any further, but i did get them to acknowledge the problem at hand and take it further towards a solution.
I'm guessing that the next step will be communication with apple regarding bonjour and either direct apple support, or feedback from apple about what the bonjour error actually means for a start.
Regardless, if i am not contacted mid next week, i will be calling and emailing them once more.

Bonjour Service continuously logging errors....

Hi everyone,
Hoping for some help with a weird problem. I've done some searching but can't a confirmed solution.
The Bonjour Service has been logging 'Task Scheduling Errors' (Error 100) on my Win7 laptop for weeks now. The behavior is erratic, but when it happens, it sometimes continues until my system hits a BSOD. Sometimes, thousands of similar messages will appear within the course of a few minutes. Here is the error output of the first few messages of a set:
Task Scheduling Error: Continuously busy for more than a second
Task Scheduling Error: m->NextScheduledEvent 1045
Task Scheduling Error: m->NextScheduledSPRetry 1045
Task Scheduling Error: Continuously busy for more than a second
From there, it's basically an endless cycle of the busy message, NextScheduledEvent, and NextScheduledSPRetry.
Any insight to these issues? I think I've been able to temporarily solve the problem by changing the Service type to 'Manual' in services.msc, but am looking for a more solution-y... solution.
Thanks much,
NS

I upgraded to Windows 7 x64 a week ago and am seeing the same sort of issues:-
26/09/2010 21:44:51 Task Scheduling Error: m->NextScheduledSPRetry 999
26/09/2010 21:44:51 Task Scheduling Error: m->NextScheduledEvent 999
26/09/2010 21:44:51 Task Scheduling Error: Continuously busy for more than a second
repeated in threes every second until

Update from itunes 9.1 to 9.2 fail, can't start bonjour service, window 7.

I am on windows 7
I try to update from itune 9.1 to 9.2 with the update tool.
When the install starts, after few steps, it trys to start the bonjour service and it fails.
How do I solve this problem?

Same problems here. Got an older itunes installed to activate my new iphone 3gs. Activated and updated the iphone's OS. After the update the iphone requires itunes 9.2 however.
Tried installing 9.2. Bonjour service cannot start, install rolls back.
(whenever i refer to bonjour "dying", i mean it cannot be started due to priviledges missing - i'm the admin lol - or service specific error 6 (0x6) in event viewer)
Uninstalled and reinstalled itunes/quicktime/bonjour several times. Got bonjour working again a few times. During 9.2 installation however, it always dies.
Tried the reloading thing (about 20 times), no go.
Tried installing Airport 5.5.1 for windows which supposedly has a better bonjour installation. Seemed to work for bonjour. However, upon installation of itunes 9.2 bonjour still dies and the install rolls back.
Tried registry changes to grant bonjour full permissions.
Tried giving the bonjour service itself administrator rights to see if i could manually start the service, no go (could not log on).
During all this i have also pilfered with windows firewall (setting exceptions or shutting it off completely), windows defender turned off, uninstalled AV and similar completely, used msconfig to make startups without anything but the itunes/quicktime/bonjour specifics, and still no go.
I'm at my wits end and tired of searching for a solution. Heeeelp!

What is bonjour service and how do I turn it back on?

I somehow turned it off. and now I cant do anything in itunes. plus it wont recognize any of my devices. everytime I go into itunes store it says error
-3212. I uninstalled itunes last night and downloaded it again this morning (I hadnt updated since last year so it was basically new version this time) but its still the same as if I hadnt done anything at all.
I have windows vista.
McAfee program.

None of that should have any relationship to the Bonjour service, which is related to iTunes Sharing (Bonjour is what your computer will use to automatically find and display other computers with iTunes Sharing turned on). Something else is almost certainly going on. Perhaps the information and suggestions in this Apple KnowledgeBase article will help:

How to disable Bonjour service advertising in Yosemite

Hi there,
I'm trying to disable the Bonjour service advertising in Yosemite / Mac OS X 10.10.
Unfortunately the instructions in OS X: How to disable Bonjour service advertising without disabling DNS no longer apply, since Yosemite no longer has /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
I did some digging around and there's someone who made a script to disable it in various Mac OS versions, including supposedly Yosemite: https://github.com/MacMiniVault/Mac-Scripts/blob/master/disablebonjour/disablebo njour-README.md
I had a look at the script to find out what it does and manually inserted "--no-multicast" as string under Program Arguments in /System/Library/LaunchDaemons/com.apple.discoveryd.plist
Doing so, will mess up the wi-fi. Networks only show when wi-fi is off, and turning it on makes it seem like it's off and I'm never able to connect until I undo the changes described above.
Wondering if:
1) The result from changes above is expected or is it a bug?
2) If Apple can update OS X: How to disable Bonjour service advertising without disabling DNS to include instructions for Yosemite.
3) Did anyone here manage to disable Bonjour service advertising in Yosemite without introducing any new issues?
Thanks!

So far, it doesn't appear to work correctly. I've posted more details in a thread here:

Bonjour Service Error 87 - WSARecvMsg failed (87)

iTunes and Bonjour Print Services Installer cannot update themselves on my Win Vista x86 SP2 machine. I keep getting an error message about Bonjour Service failing to start.
I can manually start the service by quitting the installer application, opening Services (Start > Run > services.msc), right click Bonjour Service, Restart (or Start if Restart is grayed out).
But it seems that the installer attempts and fails to restart the Bonjour Service during software update, returning error 87.
Event viewer shows:
Product Name: Bonjour
Product Version: 2.0.0.36
Event ID: 100
Event Source: Bonjour Service
Locale ID: 1033
Keywords: 0x80000000000000
Related Error with MsiInstaller: "Product: Bonjour -- Error 1920. Service 'Bonjour Service' (Bonjour Service) failed to start. Verify that you have sufficient privileges to start system services."
I have disabled Windows Defender. AVG Antivirus doesn't seem to be blocking anything. Other ideas? I can try uninstalling and reinstalling all Apple products, do you think that will fix the problem?

More Info
Related error 2: The Bonjour Service service is marked as an interactive service. However, the system is configured to not allow interactive services. This service may not function properly.
Related error 3: The Bonjour Service service terminated with service-specific error 87 (0x57).
Related error 4: The description for Event ID 100 from source Bonjour Service cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

Bonjour Service is Back!

You can un-install (remove) the Bonjour service after installing iTunes 7.6 using the Add/Remove programs (XP) or Programs and Features (Vista) control panels if you don't want this service running on your local computer (it runs as a service and communicates on your network).
This package was at one time included in iTunes to support shared iTunes libraries feature. In version 7.6, it appears to be used to support new Apple TV featues. It is not used for any other purpose.
If you don't have Apple TV, then un-install Bonjour as described above to make your computer more secure and free up some CPU cycles and RAM use.
If you purchase an Apple TV in the future, then re-installing iTunes 7.6 will install the Bonjour DNS service and provide all of the available functionality.

None of that should have any relationship to the Bonjour service, which is related to iTunes Sharing (Bonjour is what your computer will use to automatically find and display other computers with iTunes Sharing turned on).

Bonjour services 'failed to start. Verify that you have sufficient...'??

Arrgghhh!!
Been stuck here for quite a while...
I just tried to download the latest iTunes on a brand new PC (vista) and during download the computer asked whether to allow or deny access of bonjour services. Having no idea this was related to iTunes, i clicked deny. I think there was a little box ticked saying 'remember this action' or something like that. Therefore, whenever it tries to access and download, it denies access over and over without giving me a chance to intervene.
Is this to do with my avira antivirus?? or perhaps a random internet thing??
Is there any way I can change the access rights in internet settings? im going round in circles!!
I have tried many sites but to me it all sounds al gobbledy gook so is there anyone out there who can help me?? thanks
Han

Was the message about allowing bonjour access to the internet from the Vista firewall?
You should be able to configure it to allow bonjour access. There is some infrmation about configuring the vista firewall here:
http://articles.techrepublic.com.com/5100-10878_11-6098592.html
there is also this help from Apple:
http://support.apple.com/kb/TS1609?viewlocale=en_US
It may help if you have McAfee
You can uninstall bonjour if you don't need it, that's what I've done.
There is an FAQ which may help you decide if you need it.
