I have the same problem. No internet at all (IE, Outlook, etc) after
installing the 8 or so windows updates earlier in the week. I restored my
system to the point prior to installing windows updates and everything was
back to normal.

I read on here that it may be due to the IE7 update so I reinstalled the
updates minus the IE update. Afterwards, IE worked fine but Outlook couldn't
access the internet. Obviously there is another update that is doing the
same thing to Outlook settings. I tried disabling Symantec corporate edition
antivirus, but this did not help. I do not have any other 3rd party firewall
on my system. I am able to access LAN drives and other computer on my local
network.

I have Vista premium, and office enterprise 2007.

I find it hard to believe MS would put forth this update knowing it doesn't
work with other 3rd party software. I'm reading all over the internet about
people diagnosing their systems and then not installing the patches due to
this same problem. I can't even imagine what some computer illiterate people
are going through right now.

I guess if they want the ultimate in security for their software, the
ultimate solution is to totally shut down internet access
