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 上的 Windows 服务中，Service1 使用了另一个 WCF 服务（Service2) 托管在 Server2 上的另一个 Windows 服务中，当我从 WCF test client 调用 Service1 的方法时，出现以下错误：

The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:14:59.9850000'.

Server stack trace: at System.ServiceModel.Channels.ServiceChannel.ThrowIfFaultUnderstood(Message reply, MessageFault fault, String action, MessageVersion version, FaultConverter faultConverter) at System.ServiceModel.Channels.ServiceChannel.HandleReply(ProxyOperationRuntime operation, ProxyRpc& rpc) at System.ServiceModel.Channels.ServiceChannel.Call(String action, Boolean oneway, ProxyOperationRuntime operation, Object[] ins, Object[] outs, TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation) at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg) at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type) at IService1.GetHeatInstructionByOrderItemId(Int32 orderItemId) at Service1Client.GetHeatInstructionByOrderItemId(Int32 orderItemId)

但是当把 Service2 放在 Server1 上时（Server1 中有 2 个服务）方法运行没有错误。

Service2 配置：

问题出在哪里？

Answer 1

我在 Service2 上 enabled tracing，我在从 Service1.

调用 Service2 时发现以下错误

The service does not allow you to log on anonymously.

所以使用 this thread 我找到了解决方案。

我的windowsService1的账号设置为LocalSystem，所以我改成NetworkService，重新安装服务，问题解决

从另一个 WCF 服务调用 WCF 服务导致错误
