Fix for "Unidentified Network" / No Internet Access
I decided to just post this as a new thread, as it appears to be getting positive results for most people. I highly recommend it anyway, as you will eventually encounter this if you apply all of your updates...
For those of you reporting problems with your network after updating MS Office or installing Adobe CS3 -
If you are having Internet connection problems related to "Unidentified Network" showing and the "!" over your NIC icon, then this should take care of it:
Check to see if you have this little devil in your services list:
If you do, stop it and disable it. It is actually the Bonjour DNS Responder Service, and I believe it is the cause of the "Unidentified Network."
The Unidentified Network disappeared after stopping this service and a quick disable/enable of the NIC, restoring Internet access.
I Actually just rebooted, edited this post, and then re-enabled the offensive service to see what would happen...Immediately after enabling the NIC and this bastard service, the "Unidentified Network" returned...stopped it, disabled it, disable/enable NIC...Internet back up and running and no "Unidentified Network." (woot - woot!)
Hope that helps! I haven't had issues since...
FYI - I experienced this in both build 7100 and 7127...I am running 7127 now x64 - and discovered this fix just last night...so far so good just rebooted and then edited this post...I believe this fix will solve 7100 build issues too; however... I have not tested 7100 again yet.
...I also re-enabled Win 7's Discovery Mapping services, but always leave IPv6 disabled just because I am not using it.
...another two reboots, and a hard disk addition, and no problems with the Internet! - If you tried another fix such as changing the address of your network adapter, under "Advanced" - this is not necessary...I set mine back to "Not Configured." Everything is working fine as long as the Bonjour service is not running...
My system: ASUS P5E Quad Core Q6600 4GB Corsair Dominator DDR2 NIC: Marvell Yukon 8E8056; driver v10.69.2.3 (4/21/2009) ***fyi - i did update the default Windows driver with this, Vista x64 driver
For the record, there is some blame pointing towards the following software, of which I do have installed and running properly: Office 2007 SP2 Adobe CS3 (updated current)

Now I looked into my services and found the bonjour service running... hoping this was the problem with my system, instead of disabling this service, I decided that the issue might be a timing problem, and instead of disabling the service competly I set it to Automatic (Delayed Startup) as visible in this picture:
As soon as I set it like this, I restarted the machine and poof... all my issues were now gone!!!
This has been an issue since I removed a router from my network and connected directly to the newer 2Wire Modem as well as an old DLink switch...
nonetheless the most important thing is this has fixed my problems.
