401 (Unauthorized) while SSL-ing in code-behind

In my web application, I need to access a simple web site on a remote
host. That web site only allows Integrated Windows Authentication.
So, in my web application, I collect user name, password and domain
info and pass it to that remote web site.

I keep getting this Exception:

The remote server returned an error: 401(Unauthorized.)

Whereas, I can check out that website just fine in IE or FireFox by
entering my credentials. My complete code for my Login.aspx page is
available at the following address.

http://gnewsgroup.googlepages.com/sslconnectionfailureincode -behind

I am not sure where I am wrong. Many thanks if you could share a
little insights of yours into this problem.

BTW, I googled, and it seems there is very limited resource about this
problem.

Oh, BTW, when I debug the code in VS2005, I could actually see the
info of the remote site's certificate like so:

certificate = {[Subject]
CN=mercury01.mycompany.com

[Issuer]
CN=mercury01.mycompany.com

[Serial Number]
1FED32A445751AB74F0F89F2743D6447

[Not After]

[Thumbprint]
0C58396AA59FB2507BD3ADB1F6DF7...

And I verified again and again that I am using the correct username,
password and domain. But still, every time, I get this annoying
401(Unauthorized) exception.
