The NetworkCredentials are either extremely non-intuitive, or flaky, or both. Regardless, you can solve the issue by bypassing NetworkCredentials altogether and use this method (which I found, courtesy of mark.michaelis.net)

/* http://mark.michaelis.net/Blog/CallingWebServicesUsingBasicAuthentication.aspx */
byte[] credentialBuffer = new UTF8Encoding().GetBytes(username + ":" +password);
req.Headers["Authorization"] ="Basic " + Convert.ToBase64String(credentialBuffer);

So what you're doing is manually creating a header for your HttpWebRequest and inserting the content as it would appear in a Basic Authentication header. Works like a charm.
