Thread: Cannot open the sites in Internet Explorer

I have Internet Explorer 7 on my Windows Vista Business OS. Everything was OK until yesterday. Today, when I turned on my computer, some sites won’t come up. When I tried to run it, it shows the login (Required). If I enter the information, it won’t work at all. No error message, nothing. I tried with Firefox and there was no problem at all. How do I fix it?

Click on Start menu and then Control Panel and then open the Internet Options. Then, click on the Advanced tab and click on Reset button. Then, click on OK and check now whether it works or not.
