No Web Access but Broadband working fine

[oncemorealoft]

I cannot connect to the internet on my Dell home computer (Windows XP). All connections and the Broadband NTL modem have been checked.

I've done a system restore to a date when I know the computer was working fine. However, I still cannot connect to any web sites and get "page cannot be displayed" response.

I've been away for a few days and don't know if the kids have done anything.


Any ideas what to check gratefully appreciated.

Thanks
