Windows 7: No Internet Access and Bonjour service

I didn't want to hijack the 'No Internet Access' thread but having used the fixes therein have a strange problem.

I was re-installing my software, yesterday, after my 'upgrade' from 32 bit Vista to 64 bit Windows 7. Soon after my installation of Dreamweaver I lost internet access. I also noticed the icon in the notification area was showing an exclamation mark. I ran the diagnostics but Windows was unable to find a problem. I decided to do a system restore to the point before Dreamweaver was installed.

This did not fix the problem. I knew it wasn't a hardware problem because I could see and connect to the rest of the home network and I could connect to the internet using my wife's laptop connecting through the the same switch and router. I even tried using her connection cable to eliminate the cable and switch port as possible culprits.

Using my wife's laptop I found the thread that reported my exact problem. The problem, it seemed, was due to the Bonjour service. The suggested fix "How To Uninstall or Remove Bonjour mDNSResponder.exe Raymond.CC Blog" did not work for me, possibly because I had done a system restore. I was able to find and remove all references to 'Bonjour' in the registry and this removed the service and, after a restart, am now able to connect to the web.

Now my problems:

My copy of IE (64 bit) connects OK but my copy of Firefox still can't find web sites.

My copy of Outlook cannot retrieve my emails, failing with
"Task 'xxxxxx' reported error (0x800408FF) : 'Unknown Error 0x800408FF' "

Any ideas anyone, is it only 64 bit apps that will work?

Repair/reset the winsock stack. Google for help.

Thanks for that. Whilst waiting I realised that I had also installed Adobe Photoshop CS3 earlier than Dreamweaver so I decided to restore to an even earlier point. This has cured my immediate problem but I'm going to need both CS3 and Dreamweaver. I assume that once both are re-installed I can disable the Bonjour service and, if necessary, do as you suggested.

Don't just disable. Completely uninstall. There's plenty of guides on the net.

I also need to run CS3 and have had this problem. Here's the solution I've used:

In an elevated cmd window type the following command and hit OK.
“%PROGRAMFILES%\Bonjour\mDNSResponder.exe” -remove

In the same cmd, type the following command and hit OK.
regsvr32 /u “%PROGRAMFILES%\Bonjour\mdnsNSP.dll”

Reboot

Now, if you wish, you can remove the bojour directory

Thanks torrentg and srq2625

I've cut and pasted the fix into a text document on my desktop so I can find it quickly when I need it. I have several more Adobe apps and iTunes to install yet so I'll do it all when I've finished.

Just a note to say that this worked fine with one proviso.

In a 64 bit environment the Bonjour directory is in "Program Files (x86)" so %programfiles% does not find the correct location.

Run the two commands from the "Program Files (x86)" directory or substitute %ProgramFiles(x86)% and all works fine.

Scott,

Did you ever get Adobe CS3 Extended to run in Windows 7. Yesterday I had to reset the winsock four times.

The solution I indicated (and, as annotated by NormanLaw) has worked for me for months. I've even had no issues with the editing interface between LR 2.5 and CS 3.

As Scott said, no problems after performing the 2 commands. Just remember to substitute the %PROGRAMFILES% with %ProgramFiles(x86)% if you're in a 64 bit environment.
