The error message says that the code can't connect to that remote computer. Usually that is because there is no physical connection between the two computers, or else because there is a firewall or proxy or some other component which blocks the connection.
So check your network connectivity.

Thanks for your reply Paul.
yes my office uses a proxy for internet conectivity. how do i solve this issue over there. i know what the proxy ip address is.
You are doing this for work? Then your network manager should be able to help you get connected, assuming it's a work project. Although I'm a bit surprised your office doesn't have its own e-mail server which you could use.
