WCF客户端无法在某些计算机上连接

我有一个简单的自主机WCF服务。我在远程服务器上运行此服务。我能够与在我的机器上运行的客户端进行通信以提供服务(我是本地管理员(。但当我在不同的机器上运行同一个客户端(非管理员(时，它们无法通信。

我监控了资源管理器，每次服务调用和回调时，我都会看到两个随机的本地端口打开。所以我无法打开特定的端口。

知道其他机器上防火墙配置更改的可能原因是什么吗？

我是WCF的新手。如果这是一个基本问题，请原谅我。

WCF服务器代码

namespace CService
    {
    class Program
       {
       static void Main(string[] args) {
        Console.Title = "C Service";
        // Step 1 of the address configuration procedure: Create a URI to serve as the base address.
        Uri baseAddress = new Uri("http://" + GetServerIPPort.ServerIP + ":" + GetServerIPPort.Port + "/CService/Service");

        // Step 2 of the hosting procedure: Create ServiceHost
        ServiceHost selfHost = new ServiceHost(typeof(CSerice), baseAddress);
        try
        {
            // Step 3 of the hosting procedure: Add a service endpoint.
            selfHost.AddServiceEndpoint(typeof(ICService), new BasicHttpBinding(), "CService");
            // Step 4 of the hosting procedure: Enable metadata exchange.
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
            smb.HttpGetEnabled = true;
            selfHost.Description.Behaviors.Add(smb);
            // Step 5 of the hosting procedure: Start (and then stop) the service.
            selfHost.Open();
            Console.WriteLine("The Coemet Service is ready and its listening on {0}", baseAddress.AbsoluteUri.ToString() + ":" + baseAddress.Port.ToString());
            Console.WriteLine("Press <ENTER> to terminate service.");
            Console.WriteLine();
            Console.ReadLine();
            // Close the ServiceHostBase to shutdown the service.
            selfHost.Close();
        }
        catch (CommunicationException ce)
        {
            Console.WriteLine("An exception occurred: {0}", ce.ToString());
            selfHost.Abort();
        }
    }
}

我已经在这个链接的帮助下生成了Proxy对象http://msdn.microsoft.com/en-us/library/ms733133(v=vs.110(.aspx

我的客户端代码片段如下所示。

string serviceEndPointAddress = "http://" + GetServerIPPort.ServerIP + ":" +     GetServerIPPort.Port + "/CService/Service/CService";
            var remoteAddress = new System.ServiceModel.EndpointAddress(new Uri(serviceEndPointAddress));
            object rawOutput;
            using (var client = new CServiceClient(new BasicHttpBinding(), remoteAddress))
            {
                client.Endpoint.Binding.SendTimeout = new TimeSpan(0, 0, 0, 100);
                try
                {
                    rawOutput = client.GetData(Identifier, field, date);
                }
                catch (Exception e)
                {
                    errorMsg = e.ToString();
                }
            }'n
