C# – The remote server returned an error: (401) Unauthorized

chttp-status-code-401net

I'm trying to get the html code of certain webpage,
I have a username and a password that are correct but i still can't get it to work,
this is my code:

private void buttondownloadfile_Click(object sender, EventArgs e)
{
    NetworkCredentials nc = new NetworkCredentials("?", "?", "http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");   
    WebClient client = new WebClient();

    client.Credentials = nc;
    String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");

    MessageBox.Show(htmlCode);
}

The MessageBox is just to test it,
the problem is that every time I get to this line:

String htmlCode = client.DownloadString("http://cdrs.globalpopsvoip.com/0000069/20091229/20091228_20091228.CDR");

I get an exception:

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

How do I fix this?

In my case client.UseDefaultCredentials = true; did the trick.
