I am sorry that I cannot help very much but I am surprised that no one else is helping.

Can you ping that server? Do you know how to ping? You can go to a command prompt window and use the ping command with the url as a parameter, as in:

ping localhost

That is not the complete and accurate error message. Please provide the complete and accurate error message. You can use try/catch to get the complete error message.

Are you sure the firewall is allowing the connection? It might be not allowing it.
