Can not authenticate with NTLM RRS feed

  • Question

  • After I update Windows Updates(KB2805227 and KB2750149)  then I can not authenticate to my website with NTML, I've got the error (401 Unauthorized).

    I use HttpWebRequest like this:

    HttpWebRequest wReq = (HttpWebRequest)WebRequest.Create(wRequestURL);

    wReq.Method = "PROPFIND";
    wReq.Credentials = CredentialCache.DefaultCredentials;
    wReq.Timeout = 30000;

    try
    {
                    using (HttpWebResponse httpWRes = (HttpWebResponse)wReq.GetResponse()) 
                    {}

    }

    catch (WebException wex)
    {

    }

    The error at "using (HttpWebResponse httpWRes =(HttpWebResponse)wReq.GetResponse()) "

    If I uninstall the updates it's work properly.

    What's wrong? Thanks.
