Problem after installed SP2

[danlin78]

after I installed SP2, I now have two more icons in the lower right corner
of my screen. one is security centre, the other is a Local Area Connection
with a yellow sign on it, its status says 'Limited or no connectivity'. this
icon was not here before I installed SP2. now what's wrong with my network?
I tried repair it but windows fails to renew ip, how can I fix it? thanks a
lot

The security center icon is there because one of the three things it
monitors has an issue, firewall, AV and automatic updates. For firewall
and AV even if you have a 3rd party firewall and an up to date AV
program if they don't talk to the security center, and some don't, then
you get the warning. To disable these warnings click on the icon and
change the settings from there.
