Here's a tricky one - System.Net.Mail and Authentication

First...HAPPY NEW YEAR! 

I have a site that I do form authentication through Active Directory.

The readHtmlPage function is being sent the wrong page because of authentication. How in the world can I get around that?
Private Function readHtmlPage(ByVal url As String) As String
Dim result As String
Dim objResponse As WebResponse
Dim objRequest As WebRequest = System.Net.HttpWebRequest.Create(url)
objResponse = objRequest.GetResponse() ...
