我已经使用 net tcp 绑定开发了 WCF windows 服务。当 wcf 客户端和 wcf 服务都在域中（在两个不同的系统中）时，它工作正常

当两个系统都在工作组而不在域中时出现错误

请建议我需要更改哪些配置。

错误：System.ServiceModel.CommunicationException：套接字连接被中止。这可能是由于处理您的消息时出错或远程主机超出接收超时，或者是潜在的网络资源问题造成的。本地套接字超时为“00:00:58.9879193”。---> System.Net.Sockets.SocketException: 现有连接被远程主机强行关闭

根据您提供的信息，很可能是由于传输数据量大导致的错误。NetTcpbing 在局域网中会有更高的传输性能。所以你在同一个域中没有错误。WCF 默认超时期限为 1 分钟。如果一分钟内没有传输数据，就会报错。我建议你延长服务器端的超时时间：

<bindings>
      <netTcpBinding>
        <binding openTimeout="00:10:00" 
                 closeTimeout="00:10:00" 
                 sendTimeout="00:10:00" 
                 receiveTimeout="00:20:00">
        </binding>
      </netTcpBinding>
    </bindings>

此外，请启用支持 NetTCP 协议的 windows 功能。

如果问题仍然存在，请随时告诉我。

更新

如果客户端和服务器不在同一台机器上，客户端需要提供windows凭据，因为nettcpbinding默认是windows认证：

ServiceReference1.CalculatorClient calculatorClient = new ServiceReference1.CalculatorClient();
   calculatorClient.ClientCredentials.Windows.ClientCredential.UserName = "Administrator";
   calculatorClient.ClientCredentials.Windows.ClientCredential.Password = "Password";

如果这个问题仍然存在，建议添加一个 mex 端点：

<endpoint address="mex"
binding="mexTcpBinding"
contract="IMetadataExchange"></endpoint>

将 Mode 值设置为 Message：

<binding name="Binding">
          <security mode="Message">
            <message clientCredentialType="Certificate" />
          </security>
        </binding>

在你的配置文件中，我发现你没有设置Mode的值。

这是我的 App.config：

        <!-- use base address specified above, provide one endpoint -->
        <endpoint address="certificate" binding="netTcpBinding" bindingConfiguration="Binding" contract="Microsoft.Samples.X509CertificateValidator.ICalculator"/>
