win7上的WCF Duplex net.tcp问题

我们有一个WCF服务,有多个客户端来安排客户端之间的操作.它在XP上运行得很好.转到win7,我只能将客户端连接到同一台机器上的服务器.在这一点上,我认为它与IPv6有关,但我对如何继续下去感到困惑.

尝试连接到远程服务器的客户端提供以下异常：

System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://10.7.11.14:18297/zetec/Service/SchedulerService/Scheduler. The connection attempt lasted for a time span of 00:00:21.0042014. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time,or established connection failed because connected host has failed to respond 10.7.11.14:18297. —> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time,or established connection failed because connected host has failed to respond 10.7.11.14:18297

该服务配置如下：

<system.serviceModel>
  <services>
     <service
         name="SchedulerService"
         behaviorConfiguration="SchedulerServiceBehavior">
        <host>
           <baseAddresses>
              <add baseAddress="net.tcp://localhost/zetec/Service/SchedulerService"/>
           </baseAddresses>
        </host>
        <endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler"
                  binding="netTcpBinding"
                  bindingConfiguration = "ConfigBindingNetTcp"
                  contract="IScheduler" />
        <endpoint address="net.tcp://localhost:18297/zetec/Service/SchedulerService/Scheduler"
                  binding="netTcpBinding"
                  bindingConfiguration = "ConfigBindingNetTcp"
                  contract="IProcessingNodeControl" />
     </service>
  </services>
  <bindings>
     <netTcpBinding>
        <binding name = "ConfigBindingNetTcp" portSharingEnabled="True">
           <security mode="None"/>
        </binding>
     </netTcpBinding >
  </bindings>

  <behaviors>
     <serviceBehaviors>
        <behavior name="SchedulerServiceBehavior">
           <serviceDebug includeExceptionDetailInFaults="true" />
           <serviceThrottling maxConcurrentSessions="100"/>
        </behavior>
     </serviceBehaviors>
  </behaviors>
</system.serviceModel>

客户端连接如下：

String endPoint = "net.tcp://" + GetIPV4Address(m_SchedulerHostAddress) + ":" + m_SchedulerHostPort.ToString(CultureInfo.InvariantCulture) + "/zetec/Service/SchedulerService/Scheduler";

NetTcpBinding binding = new NetTcpBinding();
binding.Security.Mode = SecurityMode.None;

m_Channel = new DuplexChannelFactory<IProcessingNodeControl>(this,binding,endPoint);
m_IProcessingNodeControl = m_Channel.CreateChannel();

我已经检查过我的防火墙十几次了,但我想我可能会遗漏一些东西.尝试禁用Windows防火墙.我尝试将localhost更改为我的ipv4地址以尝试远离ipv6,我尝试删除任何反ipv6代码.

不知道它是否意味着什么,但是：

Microsoft Telnet> open 10.7.11.14 18297
Connecting To 10.7.11.14…Could not open connection to the host,on port 18297:
Connect failed

遗憾的是,telnet测试似乎并不重要.当服务运行时,我已成功从localhost和远程计算机连接到我的服务端口,但我的客户端无法从远程计算机工作.

看起来并不总能保证连接到localhost.桌面(win7 / 32)工作,笔记本电脑(win7 / 64)不起作用.其他win7 / 64盒子确实有效.也许是因为笔记本电脑上有多个网卡？也没有解释在测试人员系统上连接的失败.

我设置了两台完全禁用IPv6的win7机器(使用0xffffffff,如http://support.microsoft.com/kb/929852所示).没有帮助.
