从另一个WCF服务调用WCF服务导致错误

Question

我有一个WCF服务（ Service1 ）托管在Server1的Windows服务中， Service1使用了另一个WCF服务（ Service2 ）托管在Server2另一个Windows服务中，当我从WCF test client调用Service1的方法时，以下错误：

套接字连接已中止。 这可能是由于处理您的消息时出错，远程主机超出了接收超时或潜在的网络资源问题引起的。 本地套接字超时为“ 00：14：59.9850000”。

服务器堆栈跟踪：位于System.ServiceModel.Channels.ServiceChannel.HandleReply（ProxyOperationRuntime操作，ProxyRpc＆rpc）处，位于System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood（消息答复，MessageFault错误，字符串操作，MessageVersion版本，FaultConverter faultConverter）。 ServiceModel.Channels.ServiceChannel.Call（字符串操作，布尔型单向，ProxyOperationRuntime操作，系统处的System.ServiceModel.Channels.ServiceChannelProxy.InvokeService（IMethodCallMessage methodCall，ProxyOperationRuntime操作）。 ServiceModel.Channels.ServiceChannelProxy.Invoke（IMessage消息）

在[0]处抛出异常：在System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke（MessageData＆msgData，Int32类型）在System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage（IMessage reqMsg，IMessage retMsg）在IService1.GetHeatInstructionBy Service1Client.GetHeatInstructionByOrderItemId（Int32 orderItemId）上的Int32 orderItemId）

但把当Service2对Server1 （2个服务， Server1 ）没有错误的方法运行。

Service2配置：

问题出在哪儿？

Answer 1

我在Service2上启用了跟踪 ，并且从Service1调用Service2发现以下错误。

该服务不允许您匿名登录。

因此，使用此线程，我找到了解决方案。

我的Windows Service1的帐户设置为LocalSystem ，因此我将其更改为NetworkService并重新安装该服务，问题已解决。
