403 Forbidden

I have a laptop Sony VAIO brand new. My OS is Windows XP Media Centre (original). It has a wireless connection via the Orange Talkbox which links to another laptop (wireless) and my PC (wired).

After installing IE7 the other day, something very bad happened and I cannot access any web page via any Browser (IE, Firefox, Opera) as an Error 403 message comes up: "403 Forbidden - You were denied access because: Access denied by access control list." I have uninstalled IE7 and got back to IE6. Nothing changes. My internet connection is ok and I can access my e-mail as well as MSN and Yahoo IMs. I have tried to desactivate Norton Firewall but still doesn't help. Run the "WinsockFix" from Microsoft to make sure the Internet Connection is ok, and it is. Also, it doesn't seem to be the Livebox, as my PC and other laptop are fine accessing internet through it.

Worst than that, the System Restore function does not help neither. Although it is active, I have tried to restore to System checkpoints dates 1 month ago and even earlier and comes back to say "system cannot be restore at that date"

As if it wasn't weird enough, when I use the wireless connection at a hotspot in town sometime I can access internet all ok, sometime not.

Anybody who can help?

In advance thank you, Dan

<<it may be that your settings in connections tab of internet options is set up to use a proxy server, if so remove the tick re boot and try again.>>

That was it actually. Many thanks. Dan
