OK, I can admit when I'm beaten. I have absolutely no explanation as to how your machince is communicating in any fashion outside of it's local ip segment with no apparent default gateway for either IPv4 or IPv6.
Even more confusing "it is also only blacked on one user on one computer". Does this mean that you can log on to the problem PC as another user and everythings works fine? That would be extra special.
Whoa, very cool. I don't see any reason to do anything more drastic than to create a new user account to replace the current problem user account and then copy your doc, pictures, music, etc. over to the new account.
This may help

it's for vista but the processes is practically identical
I could always make a new account, the main reason for me posting it was actually out of curiosity. As you can see this is quite a case...
