I am using Firefox and anytime I try to access www.google.com I get the following message.

Address Not Found

www.google.co.uk could not be found. Please check the name and try again.

The browser could not find the host server for the provided address.

* Did you make a mistake when typing the domain? (e.g. “ww.mozilla.org” instead of

“www.mozilla.org”)

* Are you certain this domain address exists? Its registration may have expired.

* Are you unable to browse other sites? Check your network connection and DNS server settings.

* Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.

Any ides what could be wrong??
