Wired / Wireless dosent work

I yesterday installed Service pack 1 on my vista 32bit pc
Since then, only my wireless / wired connection shows as "identifying"
then after a while connects to my router, but as "local only" . all
other PC's in the house (one using LAN , 2 on wireless) work perfectly
fine. Prior to the installation of SP1 my Connection was perfectly fine.
thanks in advance

Edit: I removed norton, with no avail. i then used the "norton removal
tool", this then fixed the problem
