My computer is hp pavilion mx70. my os is xp home edition. my problem is when i'm on the internet and try to read my e-mail or advance to different web sites i keep getting the message "cannot find server, the page cannot be displayed. So I disconnect and reconnect to the internet and the page becomes available. But soon afterwards the problem occurs again. Along with the message there is a suggestion to change browser setting. I'm not sure how to do this
