從.net4.5轉換為.net3.5后，NTLM身份驗證不起作用

Question

以下代碼是webservice中的post方法。 問題：NTML身份驗證在.net Framework 4.5中工作正常，但我想在.net Framework 3.5中運行代碼以使項目與Windows XP兼容。

錯誤：未經授權的401

try
            {
                System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate(object sender2, System.Security.Cryptography.X509Certificates.X509Certificate certificate, System.Security.Cryptography.X509Certificates.X509Chain chain, System.Net.Security.SslPolicyErrors sslPolicyErrors)
                {
                    return true;
                };

                WebRequest request = WebRequest.Create("http://192.168.100.254"+urldata);
                request.Method = "POST";

                //NTML authentication
                CredentialCache cc = new CredentialCache();
                cc.Add(

                    new Uri("http://192.168.100.254"),
                    "NTLM",
                    new NetworkCredential("admin", "mnjkl"));
                request.Credentials = cc;


                byte[] byteArray = Encoding.UTF8.GetBytes(data);
                request.ContentType = "application/x-www-form-urlencoded";
                request.ContentLength = byteArray.Length;
                Stream dataStream = request.GetRequestStream();
                dataStream.Write(byteArray, 0, byteArray.Length);
                dataStream.Close();
                WebResponse response = request.GetResponse();

                dataStream = response.GetResponseStream();
                StreamReader reader = new StreamReader(dataStream);
                string responseFromServer = reader.ReadToEnd();
                reader.Close();
                dataStream.Close();
                response.Close();
                return responseFromServer;
            }
            catch (Exception Ex)
            {
                throw Ex;
            }

請任何了解.net3.5中的NTLM身份驗證的人幫助我。 謝謝。

我也有同樣的問題。 我能夠通過更改突出顯示的本地組策略來解決這些問題，所有您需要做的就是右鍵單擊該策略，然后單擊屬性，您需要取消選中使用128位ssl 本地組策略中的設置的屏幕快照
