ERROR IN CONNECTION while updating microsoft security essentials behind a proxy server

When u try to update the software, it tries to establish a connection to the specific website.But as you are behind the proxy the request didn't get the path to the web server and hence no connection is established.
SO before updating you must need to configure it to work through proxy rather than trying directly..


To do so :::


STEP 1: Open command prompt in administrator mode.
STEP 2: TYPE "netsh winhttp set proxy 123.212.121.121:3265"   and press enter


Replace 123.212.121.121:3265 with the address of your proxy server (same as you use in IE).


STEP 3: type exit and press enter.


You r done here now .JUST CLICK ON UPDATE now to get latest updates and enjoy the working....
