Have you tried rebooting your computer?

How are you connected to the Internet - via a dial-up modem, or via an always "on" line, such as DSL or Cable?
Is this at home or work?

What OS are you running (Windows XP ?)

If you have DSL or Cable modem try turning the power off and on the router or switch.

Make sure you don't have a loose network cable.

What do you get when you type:

 > ipconfig /all

at a command prompt?

it sounds like that you have been stoned by a kind of malware. umm... have a basic check at first: see if your host file (\windows\system32\drivers\etc\hosts) has been modified? can you PING 66.102.7.99 (an IP of www.google.com) well?

to r-k,

My yes I rebooted several times, I even repair my widows xp...

I am connected to Proxy server. The internet connection is fine. Why? because other computer connected to that proxy can use internet.

Try repairing your winsock stack with this tool:

Download, unzip and launch.

Click the FIX button and reboot when finished.

Test.

Dear JackOfPH,

Check this page http://accs-net.com/hosts/how_to_use_hosts.html
to know where the HOSTS file is located in your system.

First make a backup of the file
open it using notepad
remove all entries in there except
127.0.0.1  localhost
&
the entries that you have entered manually.
Save the file.
Restart the machine
Check if all websites would work.

did you try bbao's last suggestion?
try the winsox fix and then try mine,
