【问题描述】：

我在 Windows Server 2008 R2 Standard 上托管工作流服务。我通过在同一台服务器上运行的启用 Windows 服务/topshelf 的控制台应用程序访问它。问题是，我无法在本地（从同一服务器）访问端点，但可以从任何其他服务器（使用完全相同的服务帐户、相同的域）访问它。

我的客户端（Windows 服务）绑定如下所示：

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BindingIBeginNewRequestAdded">
                    <security mode="Transport">
                        <transport clientCredentialType="Windows"/>
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://WorkFlowServerTest.corp.gdg/NewAccountRequestWorkflow.xamlx" binding="basicHttpBinding"
                bindingConfiguration="BindingIBeginNewRequestAdded" contract="NewAccountRequest.IBeginNewRequestAdded" name="BindingIBeginNewRequestAdded"/>
        </client>
    </system.serviceModel>

WorkFlow 服务绑定如下所示：

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="HTTPSBindingConfiguration">
          <security mode="Transport">
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
        <binding name="MEXHTTPSBindingConfiguration">
          <security mode="Transport">
            <transport clientCredentialType="Windows" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="HTTPSBehavior" name="NewAccountRequestWorkflow">
        <endpoint address="mex" binding="basicHttpBinding" bindingConfiguration="MEXHTTPSBindingConfiguration" contract="IMetadataExchange" />
        <endpoint binding="basicHttpBinding" bindingConfiguration="HTTPSBindingConfiguration" name="SecureTransportNoCredentialsEndpoint6" contract="IBeginNewRequestAdded" />
      </service>
    </services>

C#/Windows 服务代码：

NewAccountRequest.BeginNewRequestAddedClient _ws = new NewAccountRequest.BeginNewRequestAddedClient();
_ws.BeginNewRequestAdded(_newRequest.RequestID);

错误：

System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'. ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized.

所以我知道这一点：https://support.microsoft.com/en-us/kb/896861

并且已经将 WorkFlowServerTest.corp.gdg 的 BackConnectionHostNames 添加到 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0。

我已经尝试了绑定中客户端和服务器 clientCredentialType 和安全模式设置的所有组合。迷路了……

【解决方案1】：

答案是注册表设置：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0\BackConnectionHostNames

...不正确！

所以，我尝试将其指向我的 WorkFlowServerTest.corp.gdg DNS。但是该 DNS 只不过是指向该服务器的 FQDN 之一的 CName。分辨率：

Ping 该 CNAME/DNS 名称以获取 IP 地址。 NSLOOKUP 该 IP 以获取 FQDN。将注册表项设置为 FQDN 并修复它。已修复！
