Hi bernardleug,

try this
in 'Tools' Menu of your IE 8 click on 'Internet Options'
'Connections' Tab and click on 'LAN Settings'
make sure you have 'Automatically detect settings' checked.

hope this helps.

Can you open up another web browser, (like firefox), and check if it can connect with it.

Do you need to enter in proxy details manually into IE8?

Make sure you are connected to the internet.

Check your network setting or internet connection, dns setting.
Go to http://www.opendns.com  and signup for an OpenDNS Free account, configure your router or computer to use openDNS settings and in the OpenDNS dashboard.
Or maybe just mistype site ?
Please let me know how it works out for you
