c# – 对SSPI的调用失败,第二次运行调用时会看到内部异常吗？

public GetUserDataResponse GetUserDataFromService(X509Certificate2 certificate)
{
    ChannelFactory<MyApp4SITHSService.IMyApp4SITHSServiceContract> factory = new ChannelFactory<MyApp4SITHSService.IMyApp4SITHSServiceContract>("NetTcpBinding_IMyApp4SITHSServiceContract_Certificate");
    MyApp4SITHSService.IMyApp4SITHSServiceContract service;
    GetUserDataResponse response;

    factory.Credentials.ClientCertificate.Certificate = certificate;
    //factory.Credentials.UserName.UserName = "me";
    //factory.Credentials.UserName.Password = "password";

    service = factory.CreateChannel();

    LogHandler.WriteLine("Connecting to service");
    response = service.GetUserData(new GetUserDataRequest());
    LogHandler.WriteLine("Data received");

    factory.Abort();
    return response;
}

我第一次运行它时效果很好,第二次在service.GetUserData上得到以下异常：

A first chance exception of type ‘System.ServiceModel.Security.SecurityNegotiationException’ occurred
in mscorlib.dll

A call to SSPI failed,see inner exception.

The Local Security Authority cannot be contacted

我使用以下配置：

知道我为什么会遇到这个问题以及如何解决它？
