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? (”

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.
