Open Tools[Internet Options][Privacy tab] and put one of these web sites in the list
which can be located by clicking the Sites button.

begin to diagnose cookie/script problems with that site and your Internet zone settings.

If you are a dial-up user and your ISP have more than one local number for dialup,
remove the primary number that is dialing up first and use the secondary dialup

A file in your Windows folder called 'hosts' (no extension) may have an incorrect IP
address for the page. To find out, open Windows Explorer, select your C:\Windows
folder, and look in the right pane for a hosts file. If you can't find it in your Windows folder, this isn't your problem. If you do find a hosts file, open it in Notepad and look for a line referring to the page that's giving you trouble. If it's there, enter # at the beginning of the line. Save and exit the file.

Go to Tools[]Internet Options[]Connections[]Lan Settings. Uncheck Use a proxy
server. Now restart IE.
These steps will definitely solve the issues.
