Unidentified Public Network & Invalid IP Address

Hello. I have been using Windows 7 for about a month now and two days ago i started to have network problems.

I cannot connect to the internet or my network and keep getting messages saying that the network cable is unplugged when it is not. After a while i was able to get a different message and the computer connects to an unidentified network and when i troubleshoot this it tells me i have an invalid IP address.

I know the problem has got nothing to do with the hardware or my internet. I have tried 2 other router's & another modem with different ethenet cables with no luck but my network/internet is working fine on my laptop which is also Windows 7.

What about switching out the NIC on the PC? Have you tried that?

No i have not tried this as i don't have a second one. But i have uninstalled the drivers and re-installed them with no luck.

Did you recently install adobe photoshop or CS?

Adobe products install a service called Bonjour that on W7 messes with the DNS in such a way as to create invalid entries in your gateway list causing this exact problem.

There is an article/thread on here about how to remove it. Sorry I don't have the info at my fingertips atm...

[Edit] Ooops, this doesn't sound the same actually, Never mind!

(Here is the thread anyway)

It started working about 30 minutes ago but stopped working again after about 10 minutes so dunno wether it can be the NIC.

I have tried Clearing my Cache to with no luck.

I actually installed Adobe Photoshop & Dreamweaver about a week ago but i think i unselected Bonjour to be installed with it and i cannot find it in my services list either.

I did IPCONFIG/ ALL in CMD and this is what it told me.
