I have a Windows Vista Home Premium 64 bit system, It has IE and Mozilla on it.
Mozilla can connect to the iternet and browse without issues. IE cannot. Also any program that checks for updates cannot get those updates. I can open a dos box and type in an address (msn.com) and it will resolve to an IP address. I can also ping an address outside the firewall.
I have removed and re-installed SP2
I have removed AOL, IE9, IE8 and then re-installed IE-8.
I have reset the tcp/IP stack
I have cleared the cookies on IE, as well as resetting all advanced setting in Internet options..
