在上传文件时出现401未经授权的错误

Question

I have an asp.net application that submits files to a sharepoint document library. Each time it tries to submit I get a

The remote server returned an error: (401) Unauthorized

Here is the c# code

                    byte[] buffer = new byte[length];
                    postedFile.InputStream.Read(buffer, 0, length);


                    Uri address = new Uri(url);
                    HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
                    request.Method = "POST";

                    request.UseDefaultCredentials = true;

                    request.Accept = "application/json;odata=verbose";
                    request.Headers.Add("X-RequestDigest", dvalue);
                    request.ContentType = "application/json; charset=utf-8";
                    request.ContentLength = length;
                    using (Stream postSTream = request.GetRequestStream())
                    {
                        postSTream.Write(buffer, 0, length);
                    }
                    using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
                    {
                        StreamReader reader = new StreamReader(response.GetResponseStream());
                    }                       

This works fine on my local machine, but when I deploy it to our test environment, it raises the 401 error. IIS is configured for anonymous authentication. I think it is something to do with the file upload? Any insight or thoughts are appreciated!

Thanks
