It is a pc with win98se PIII, 256k and now I am unable to use internet and all what I got is: Page not found. i called to telefonica and asked where could be the problem and he told me that the operative system had problems after following some steps he indicated: run--command- enter
then I wrote ipconfig and had the info they requiered as the IP address. Then I wrote Ping and the response was file not found.
According to it what can I do to fix the problem.

Following the same steps go to run--->command(or CMD)--->hit enter. Then type ipconfig /release hit enter. Note the space before the slash, it has to be there or it won't work. Then type ipconfig /renew, note the space again. That will tell your computer to release and renew the IP address. If that doesn't work, then it is more then likely your ISP's problem.

Thanks bigboy I will do and then advice.
