I have using ubuntu 12.04LTS with all available updates installed. Some websites are not opening in any browser, i have tried many browsers(firefox,chrome,chromium,arora,xxxtrem browser,Midori).
But yesterday i have install the ubuntu 12.04(the first release of this version) in my pen drive and use it. In USB booted ubutu, all websites are open properly or we can say that in older version of browsers websites are opening(in usb booted ubuntu firefox version is 11.0) but now in updated ubuntu 12.04LTS websites are not opening .
I have read some solution about this problem but they are says to change dns server but i think this is not dns server problem because with same dns settings websites are opening properly in the windows and usb booted ubutu.
Please tell what will be solution?
website which i tried to open are
yahoo.com, skydrive.live.com, indiarailinfo.com
