VS 2010 Check if server is respondign (online).

Hi all.

I have the IP of the login server of a game. I want to see if the server is online because
i'm making a tool to check if it's online when it's on a patch. Once the patch is over, it will
notify you. I've tried using this method:

The problem is, it takes about 30 second for the ping to work to get response. I've seen other
server checkers tools for that game I'm plaing and people made it somehow so it checks if it's
online in no time! If you set the check delay to 1second it will still check correctly! How did they do it?

Thanks.
