.NET Remotting 问题 求助：【由于目标机器积极拒绝，无法连接。 127.0.0.1:8089】 如何解决

生成远程对象的接口：
namespace RemottingObjectInterface
{
public interface IHello
{
string Greeting(string name);
}
}

远程对象：
namespace RemottingObject
{
public class Hello : System.MarshalByRefObject, IHello
{
public Hello()
{
Console.WriteLine("Hello's Constructor is called !");
}

~Hello()
{
Console.WriteLine("Hello's Destructor is called !");
}

public string Greeting(string name)
{
Console.WriteLine("Greeting called !");

return "Hello" + name;
}
}
}

客户端调用代码：
namespace TestClient
{
class Program
{
static void Main(string[] args)
{
//TcpClientChannel channel = new TcpClientChannel();
//ChannelServices.RegisterChannel(channel, false);

//IHello hello = (IHello)Activator.GetObject(typeof(RemottingObjectInterface.IHello), "tcp://localhost:8089/Hi");

RemotingConfiguration.Configure("TestClient.exe.config");

IHello hello = (IHello)Activator.GetObject(typeof(RemottingObjectInterface.IHello), "tcp://localhost:8089/Hi");

Console.WriteLine(hello.Greeting(" - Guoxc"));

}
}
}

服务器端配置文件：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<application>
<service>
<channels>
<channel ref="tcp" port="8089"/>
</channels>
<wellknown type="RemottingObject.Hello,RemottingObject" mode="SingleCall" ObjectUri="Hi">
</wellknown>
</service>
</application>
</configuration>

客户端配置文件：
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.runtime.remoting>
<application>
<client>
<wellknown type="RemottingObjectInterface.IHello, RemottingObjectInterface"

url="tcp://localhost:8089/Hi" />
</client>
</application>
</system.runtime.remoting>
</configuration>


********问题******************

安装并启动了Windows服务承载远程对象“Hello ”，执行客户程序抛出异常，异常信息为：【由于目标机器积极拒绝，无法连接。 127.0.0.1:8089】
问题出在哪里，请前辈们解决，不胜感激！！
