Few days ago, my IE 6.0 and firefox suddenly failed to go to any website including yahoo and etc ... It showed "cannot find the webpage". I am connecting to Internet through broadband at home and I figure out the connection is still through and I still can ping to the website. But IE or firefox cannot go anywhere. , I tried to use ip in IE but still doesn't work. And I tried to run netsh winsock reset command. Things are getting worse. I cannot even connect to the ISP. The error message is 619... One thing I am not sure if it is related, the firewall is turned off automatically sometime when I reboot winxp. Then I used another computer with the same line and it works. I brought my computer to a computer expert. My computer can connect with his line. Now when I double-click the window firewalls in control panel, I got error message "the firewall failed to open ..." and then nothing happen and the firewall cannot be turned on. Some people told me to post the problem here. Can anyone please help me? Thanks.
