Internet Explorer is not opening the website, But Firefox does. Why? I have checked Internet connectivity is fine. There is no Proxy Setting enabled on Tools->Option and LAN Settings IE. I did reset IE default settings. To the extent, i did reset Winsock to see Internet work on IE. But still not working. Windows Firewall is switched off. I have Mcafee Installed, But Internet is allowed, and there is no restriction for IE. Any Inputs Please. I am facing this in one our Production server in Organisation and i am unable to get the Windows updates.
