我有一个客户端和服务器应用程序，通过Visual Studio 2010在同一台机器上本地运行时可以正常通信。如果我编译服务器应用程序并将其移动到托管在同一台机器上的Windows XP VM并发布客户端，我可以毫无问题地进行方法调用。当我将同一个服务器应用程序移动到同一网络上的单独物理机器时，我无法调用该服务。
我通过此次调用在服务器中托管服务：
host = new ServiceHost(typeof(ClientHealth));
host.Open();
使用以下代码在客户端访问它：
try
{
if (client.InnerChannel.State != System.ServiceModel.CommunicationState.Faulted)
{
client.ReportHealth(DataMinder.clientIpAddress, DataMinder.clientName, DateTime.Now);
}
else
{
client = new ClientHealth.ClientHealthClient();
client.Endpoint.Address = new EndpointAddress("net.tcp://" + DataMinder.serverIpAddress + ":" + DataMinder.serverPort + "/");
}
}
catch (Exception ex)
{
Debug.WriteLine("Failed to connect to host");
Debug.WriteLine(ex.Message);
}
我收到错误： ＆＃34;套接字连接中止。这可能是由于处理消息的错误或远程主机超出接收超时或基础网络资源问题引起的。本地套接字超时为＆＃39; 00：04：59.9532000＆＃39;。＆＃34;
这是我的客户端app.config

赔率是没有超时问题，但是你没有回答就达到超时，不是由于时间问题，而是由于一个问题导致它永远无法回答（5分钟已经很大）。 诊断它的最佳方法是更改配置（在客户端和服务器端）以记录WCF事件
http://msdn.microsoft.com/en-us/library/ms730064.aspx
然后在服务器上查看它们，如果服务器端为空，则它没有接收任何连接＆amp;移动到客户端的日志可能会告诉您有关错误的更多信息，如果您仍然没有得到任何信息，请联系网络管理员，这很可能是网络问题。

在您的客户端app.config中，您仍然连接到localhost：
<client>
<endpoint address="net.tcp://localhost:10001/" binding="netTcpBinding"
bindingConfiguration="NetTcpBinding_IClientHealth" contract="ClientHealth.IClientHealth"
name="NetTcpBinding_IClientHealth">
<identity>
<userPrincipalName value="Maelstrom\Josh" />
</identity>
</endpoint>
</client>
在端点的地址中，您必须放置服务器的IP地址或主机名，包括端口。

我进一步挖掘net.tcp绑定，事实证明我使用的是安全模式的传输，我应该使用无安全模式。我将安全模式none标记添加到客户端和服务器，并且能够正常连接。它在虚拟机上运行的原因是我使用的凭据是实现/转移到虚拟机的，因为它是在同一台机器上托管的。
感谢大家的帮助。
