Flash CS3 trial breaks Juniper Network Connect
It’s been a long time since I’ve posted here because I have been crazily busy working on a massive flex site with a great team over at Tribal DDB London. Hopefully it will go live at the start of next year so I can talk more about it. In the meantime, here is a quick tip for anyone having trouble connecting to a VPN powered by Juniper software’s Network Connect after installing the trial version of Flash CS3.
After installing a trial of Flash CS3 I noticed that I became unable to connect to the VPN. Network Connect would connect briefly and then pop up an alert saying “The Network Connect session terminated. Do you want to reconnect? (nc.windows.app.23711).”
After a bit of googling I found out that there were complaints about the early betas of CS3 and the Bonjour service that they installed affecting networking. And this is what was causing my problem. If you press Ctrl-Alt-Del and look at your processes then you will find a “mDNSResponder.exe” service running after installing Flash CS3. Ending this process allows you to connect through Network Connect.
You will have to do this every time you have restarted your computer as the process is automatically started with the system. Alternatively you can stop the service which starts the mDNSResponder process.
Go to Start Menu > Run and type in “services.msc” to open the services configuration panel. Look for a service with a name something like ”##Id_String1.6844F930_1628_4223_B5CC_5BB94B879762##” (I think the bit after the dot will change on each computer). To confirm it’s the correct service double click on it and look at the “Path to executable” – it should be “C:\Program Files\Bonjour\mDNSResponder.exe”. If it is then change the “Startup type” to “disabled” and press the “Stop” button. You should now be able to connect to your VPN.
As far as I can tell, neither of these solutions have had a detrimental effect on my trial install of Flash so I think that they are safe changes to make but no guarantees! Hopefully the information will save someone the time it took me to find the answer.

FYI
For me the application in the services panel wasn’t ”##Id_String.. etc” but “Bonjour Service”.

Ending the process “mDNSResponder.exe” was the solution for me. Thanks

Thanks for sharing. I’ve almost had to rebuild my new laptop because of this issue. In my past experience, the new KODAK EasyShare does the same thing to NC. The only solution I’ve found was to completely rebuild the PC and not to install EasyShare at all…

Is the “mDNSResponder.exe” service named different for Vista?
— Different for Vista? Apr 17, 13:35 #
It is commonly installed with the following software:
•Apple applications including iTunes, iPhoto, and iChat
1. Open a Windows command prompt and type the following command: “C:\Program Files\Bonjour\mDNSResponder.exe -remove” 2. Navigate to the following folder in Windows Explorer: C:\Program Files\Bonjour 3. Rename the mdnsNSP.dll file in that folder to mdnsNSP.old 4. Restart your computer 5. Delete the Program Files\Bonjour folder•All Adobe CS3 software
•Trillian Pro
•Flash Player 9
•Gizmo Project
Removing Bonjour for Windows
with the Adobe Master suite if you do a custom install you can elect to not install the Bonjour service.
with iTunes 7.5 and up the service will appear as Bonjour and can be removed from the control panel>add/remove programs
I run into this issue all the time on various builds XP/Vista (this does not effect MACs)
This will also effect Juniper Windows Secure Application Manager

If Bonjour isn’t on there and none of those apps are on there then what? Does anyone have a good solution? Running Vista Ultimate with almost no apps installed.
Thanks
— Josh May 5, 03:50 #
Thnx, This was exact the problem a user had at home and she mentioned bonjour was standing in her firewall. If not I never would have come on this site and solution!. thnx again.
— shaka May 9, 10:51 #
I had terrible time with this error message. While googling this on the web, this page was the first hit. Thanks for this information. For me it was Bonjour service. This was satrted:automatic. I first stopped and then disabled it.
— VG May 9, 19:15 #
Thank you so much for your help. That was exactly what i was looking for!
— André May 10, 09:05 #

Adobe says this can be disabled – it’s only used for Macs and contribute authentication – also shows you how to delete the service.
— NeSmith Jul 18, 21:24 #
Your post also resolved my issue. Thank you.
— Brian Jul 24, 04:07 #
Thank you very much.
Knew about Bonjour but couldnt work out why this was failing on a different machine with no itunes. Now i do! CS3 trial!!
Thanks again.
— Pii Jul 28, 16:10 #
I found that once Bonjour is disabled the iTunes assistant tells you that it enables file sharing, connecting to AppleTV, etc. Fortunately I don’t need those services but just FYI for others.
