I am the host on a home network and my daughter is the client. We both have XP and I connect to the internet using a USB ADSL modem. The network seems to work in all respects except that web pages are unavailable on the client computer. She receives Windows update installation notifications, can send and receive e-mail,and use Windows Messenger, so it seems as if the ICS is working but whenever she tries to open Internet Explorer she gets the "page unavailable" screen. She has tried to access several different sites (including Microsoft) so it is not just a problem with the site she is trying to access.
Any suggestions please as I can't think of what to try next.
