Anyone with similar problem or solution ?

I am operating with a windows XP system US Version, and I can display yahoo.com or google.com but for some specific search I need to use baidu.com

Nor Firefox or Chrome allow me to access to it, I always arrive to "can't access the website requested page''

I am using my own China Telecom internet box to connect to internet, so I really don't see where is it coming from.
I also don't use VPN, and don't want to think I would a VPN to access Baidu.com, it's a nonsense ;-)

Thanks for any help.
