HTTP Get to Report Server 2008 arbeitet mit DefaultCredentials, schlägt mit einigen NetworkCredentials fehl

Question

Das folgende WithDefaultCredentials() funktioniert, aber WithCredentialsMe() schlägt mit einem HTTP 401 fehl, das zurückgegeben wird? Der Unterschied ist, dass ICredentials-Anmeldeinformationen = System.Net.CredentialCache.DefaultCredentials; funktioniert OK für die Berichtsserver-URL 2008, aber ICredentials-Anmeldeinformationen = new NetworkCredential ("myUsername", "myPassword", "ourDomain"); kommt wieder mit einem HTTP 401.

Die Konsole App wird von mir entwickelt, so sollte es keinen Unterschied zwischen DefaultCredentials und NetworkCredential sein. Es gibt kein Problem mit meinem Benutzernamen und Passwort.

Irgendwelche Ideen?

static void Main(string[] args) 
{ 
    WithDefaultCredentials(); 
    WithCredentialsMe(); 
} 
public static void WithDefaultCredentials() 
{ 
    try 
    { 
     ICredentials credentials = System.Net.CredentialCache.DefaultCredentials; 
     string url = "http://myBox/ReportServer_SQLSERVER2008/Pages/ReportViewer.aspx?%2fElfInvoice%2fElfInvoice&rs:Command=Render&InvoiceID=115abba9-61bb-4070-bd28-f572115a2860&rs:format=PDF"; 
     var bytes = GetByteListFromUrl(url, credentials); 
     File.WriteAllBytes(@"c:\temp\A_WithDefaultCredentitials.pdf", bytes.ToArray()); 
    } 
    catch (Exception ex) 
    { 
     Console.WriteLine(ex.Message); 
    } 
} 
public static void WithCredentialsMe() 
{ 
    try 
    { 
     ICredentials credentials = new NetworkCredential("myUsername", "myPassword", "ourDomain");

    } 
    catch(Exception ex)

public static List<Byte> GetByteListFromUrl(string url, System.Net.ICredentials credentials)

    List<Byte> lstByte = new List<byte>(); 
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
    if (credentials != null) 
    { 
     request.Credentials = credentials; 
    } 
    var response = (HttpWebResponse)request.GetResponse(); 
    var stream = response.GetResponseStream(); 
    int totalBytesRead = 0; 
    int bufferbytesRead = 0; 
    try 
    { 
     byte[] buffer = new byte[1024]; 
     while ((bufferbytesRead = stream.Read(buffer, 0, buffer.Length)) > 0) 
     { 
      totalBytesRead += bufferbytesRead; 
      if (bufferbytesRead < buffer.Length) 
      { 
       bufferbytesRead = bufferbytesRead - 1 + 1; 
      } 
      for (int i = 0; i < bufferbytesRead; i++) 
      { 
       var bToAdd = buffer[i]; 
       lstByte.Add(bToAdd); 
      } 
     } 
    } 
    catch (Exception ex)

    } 
    finally{} 
    //-Return 
    return lstByte;

Mit Hilfe http://forums.asp.net/t/1217642.aspx dieser Code mir bekam, was ich wollte ... Der nächste Schritt ist sauber alles und Unit-Test in dev ...
