Using HTTPWEBREQUEST----->Very Urgent

Geeks, I am really Puzzled by this problem: I am trying to connect to an intranet site (HTTPS site and I already have client certificate) from my machine using HTTPWEBREQUEST using C# windows application and I am getting message: "the underlying connection was closed: the remote name could not be resolved" Important points to be noted: -Same site address (.JSP pages) works fine from browser but from C# I get above message. -The .JSP pages I am trying to connect is not a WebSERVICE. -Site is behind firewall. -The other thing I have is IP Address of the machine. I believe (not sure) is there anything on proxy settings I need to do and if yes then please tell mehow to setup the proxy settings while using HTTPWEBREQUEST? (Remember I know the IP Address of the machine). I am already trying to find help from one of this link but not much success: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemNetHttpWebRequestClassProxyTopic.asp
