    Hello Everybody,

    I'm using this code to get XmlDocument from url:

                using (WebClient wc = new WebClient())
            {
                wc.Credentials = new NetworkCredential("admin", "admin");
                string xml = wc.DownloadString("http://192.168.1.187:8550/epe/pos/taglist");

                XmlDocument tournamentsXML = new XmlDocument();
                tournamentsXML.LoadXml(xml);


                XmlNodeList TagList = tournamentsXML.GetElementsByTagName("TAG");
                foreach (XmlNode node in TagList)
                {
                    XmlElement TagElement = (XmlElement)node;
                    string TagID = TagElement.GetElementsByTagName("tagid")[0].InnerText;
                    string MAC = TagElement.GetElementsByTagName("mac")[0].InnerText;
                    Data.Add(new Tag(TagID,MAC));
                }
            }

    It's work fine,

    But when I change the link to "http://192.168.1.187:8550/epe/pos/taglist?fields=posgood"
    it give me error message "The remote server returned an error: (401) Unauthorized."

    By the way when I copy past the same link "http://192.168.1.187:8550/epe/pos/taglist?fields=posgood" to browser it retreive XML data exactly !!

    Please help me please :(

    Cut us some slack, it's in the middle of the night in the US.

    Are you SURE the credentials in your browser are the same as what you set up in the program?   401 errors indicate authentication problems.    Have you checked the configuration on that server?

    I think you should ask this to your System Admin. 

    The IP address is located in your own network so your system admin should know 

    Otherwise try this microsoft forum

    Use fiddler to see what exactly those browsers send to the server and simulate that in your code. There are all kinds of reasons that you may get a 401, for example some servers limit verbs to Get or Put.

    Hi Shakatra,

      Welcome to MSDN Forum Support.

      If your problem doesn't use the Microsoft technique or its related product, I am sorry that I can't support you due to its outside of the scope we should do. Hope you understand us. Furthermore, we need to move your thread to Off-topic.
