WebTicket - DMS Failed open document

[#1]

Hi all.... I Recently installed QV11.2 in 3 machines. machine1 QVS, machine2 QVP and machine3 IIS7.5...... I tried to use QMS API... to open a document, but I have a problem using webTickets.... with DMS

Apparently I get the webticket... but when the docoment is open I get two errors message:

***When I try to open with  QvAjaxZfc: "You do not have permission to view this directory or page" 

url : 

http://tcb-web/qvajaxzfc/authenticate.aspx?type=html&try=tcb-web/qvajaxzfc/opendoc.htm?document=pr.q...

****when i try to open with QvPlugin: "Failed to open document, You don't have access to this document" (QlikOcx)

url:  http://tcb-web/QvPlugin/opendoc.htm?document=pr.qvw&webticket=HFO+b8ZTGg8X0K1SuHmOJnztub6y3PxXneijFz...

.I have my IIS server with anonymous account , the default web site with anonymus auth, also the app QvAjaxZfc with anonymous and the webticket.aspx with windows auth ....

I think my C # code gets in a wrong way the webticket. Because when I concatenate into a url i get that errors. Also... when I use the GetTicket.aspx file instead GetWebticked.aspx the value of the ticket is empty.

p.s. when I configure the document with "All users" permission QvPlugin opens the document correctly, but this isn't that I want.

QVS: tca-qvs

QVP: tca-qvp

QVWS: tcb-web (iis 7.5)

 public static string getTicket(string User)
        {
            string usergroups=@"";
            string QlikViewServerURL = "http://tcb-web/QVAJAXZFC/GetWebTicket.aspx";
            StringBuilder groups = new StringBuilder();
            if (!string.IsNullOrEmpty(usergroups))
            {
                groups.Append("<GroupList>");
                foreach (string group in usergroups.Split(new char[] { ',' }))
                {
                    groups.Append("<string>");
                    groups.Append(group);
                    groups.Append("</string>");
                }
                groups.Append("</GroupList>");
                groups.Append("<GroupsIsNames>");
                groups.Append("true");
                groups.Append("</GroupsIsNames>");
            }
            string webTicketXml = string.Format("<Global method='GetWebTicket'><UserId>{0}</UserId></Global>", User);
            HttpWebRequest client = (HttpWebRequest)WebRequest.Create(new Uri(QlikViewServerURL));
            string uri = client.RequestUri.ToString();
            client.PreAuthenticate = true;
            client.Method = "POST";
            client.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
            NetworkCredential myCred = new NetworkCredential("user", "pwd", "domain");
            CredentialCache myCache = new CredentialCache();
            myCache.Add(new Uri(uri), "NTLM", myCred);
            client.Credentials = myCache;
            var writer = new StreamWriter(client.GetRequestStream());
            writer.Write(webTicketXml);
            writer.Flush();
            var reader = new StreamReader(client.GetResponse().GetResponseStream());
            var xmlDocument = new XmlDocument();
            xmlDocument.LoadXml(reader.ReadToEnd());
            return xmlDocument.InnerText;
        }

Any clue?

Thanks a lot!
