Can't Authenticate to SiteMinder protected resource that requires NTLM authentication

[JoeMITRE]

Url is a location in the same domain, but not the same machine.

I do not have admin access to either SiteMinder or the the target machine.



No matter what I've tried, and I've tried a lot, I cannot get past the first Request.GetResponse() call. Because of this I cannot get the header, I cannot get the cookies, I cannot get the SMAgentID.



This line: Response = (HttpWebResponse)Request.GetResponse();

throws this error: "The remote server returned an error: (401) Unauthorized." at System.Net.HttpWebRequest.GetResponse(), in Main()
