http://www.microsoft.com not accessable.

http://www.microsoft.com is not accessable from the windows server.

Just check the other sites of windows are working like

http://support.microsoft.com

http://www.msn.com

Then we can see that only the name microsoft.com  has the problem.

Just Do

" net stop dnscache " On the command line.

Then just refresh the browser you will see the http://www.microsoft.com on your browser.
