Hi,
I would like to verify whether you cannot access all website or a special website?
You can try to
follow the steps here
http://stackoverflow.com/questions/681695/what-do-i-need-to-do-to-get-internet-explorer-8-to-accept-a-self-signed-certifica to
add the certificates.
If it doesn’t help,
you can also try
to synchronize your computer's clock with an Internet time server
1. Click the
Start button, click Control Panel, click Clock, Language, and Region, and then click
Date and Time.
2. Click the Internet Time tab, and then click
Change settings. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click Automatically synchronize with an Internet time server, select a time server, and then click
OK.
