ASP.NET + NetworkCredentials，登录尝试失败

我有一个需要Windows集成安全性的ASP.NET应用程序。出于某种原因，我不想在这里讨论什么，我需要在运行时创建WebRequest，调用应用程序中的其他页面并处理结果。ASP.NET + NetworkCredentials，登录尝试失败

该应用程序在我们使用DNS别名的服务器上运行，类似于app.domain.com。

因此，我使用预定义的域用户名和密码创建NetworkCredential，并将其附加到请求中。

这就是我得到：

[Win32Exception (0x80004005): The logon attempt failed] 
    System.Net.NTAuthentication.GetOutgoingBlob(Byte[] incomingBlob, Boolean throwOnError, SecurityStatus& statusCode) +1404402 
    System.Net.NTAuthentication.GetOutgoingBlob(String incomingBlob) +78 
    System.Net.NegotiateClient.DoAuthenticate(String challenge, WebRequest webRequest, ICredentials credentials, Boolean preAuthenticate) +560 
    System.Net.NegotiateClient.Authenticate(String challenge, WebRequest webRequest, ICredentials credentials) +14 
    System.Net.AuthenticationManager.Authenticate(String challenge, WebRequest request, ICredentials credentials) +247 
    System.Net.AuthenticationState.AttemptAuthenticate(HttpWebRequest httpWebRequest, ICredentials authInfo) +243 
    System.Net.HttpWebRequest.CheckResubmitForAuth() +232 
    System.Net.HttpWebRequest.CheckResubmit(Exception& e) +5299747 

[WebException: The remote server returned an error: (401) Unauthorized.] 
    System.Net.HttpWebRequest.GetResponse() +5313085 
    Entropy.Envoy.Web.Corporate.ExportFilter.GetTargetReportContent(Uri targetUrl, HttpCookieCollection cookies) +521 
    Entropy.Envoy.Web.Corporate.ExportFilter.Page_Load(Object sender, EventArgs e) +139 
    System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14 
    System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35 
    System.EventHandler.Invoke(Object sender, EventArgs e) +0 
    System.Web.UI.Control.OnLoad(EventArgs e) +99 
    System.Web.UI.Control.LoadRecursive() +50 
    System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627

相同的代码工作在其他服务器上使用类似的设置虽然。发生了什么事？

找到了答案。原来如同将Active Directory添加到SPN一样简单：

setspn -a HTTP//WebServer.domain.com customDomainAccount 
setspn -a HTTP//servername customDomainAccount
