Can't send web based email

[BarefootJ]

Windows 98
Using any web browser(IE and Netscape, etc.)

I can logon to yahoo or other web based email sites, but whenever I try to send email on one of our computers, it cant find the site and wont send.


I dont know if the problem is related, but I also cant post this thread from the computer as well(im using another one to post this).

In yahoo I can only load my mail screen. If I try and click any option like 'inbox', it searches and wont find the site.

Help!

What message do you get? Can't display page?
Do you have a firewall or antivirus software? Which one?
