I have built the application as follows. But i'am getting an error as "The remote server returned an error: (404) Not Found". Can anyone tell how to correct that error. Please help me out.

Build a Simple Remote Object

Hello.cs(Class library)

using System;
using System.Runtime.Remoting;

namespace HelloWorldObject
{
    public class Hello : MarshalByRefObject
    {

        public string HelloWorld(string str)
        {
            return "Hello World received " + str + " from the client";
        }
    }
}

Add references to the following:
1) System.Runtime.Remoting


Host the Remote Object in Microsoft Internet Information Services

1) Create a new directory called HelloWorldWeb (preferably under \Inetpub\wwwroot\).
2) Create a directory named bin beneath the HelloWorldWeb directory.
3) Copy the HelloWorldObject.dll file from the HelloWorldObject\bin\debug\ directory to the HelloWorldWeb\bin\ directory.
4) Use Notepad.exe to create a new file called Web.config. Copy the following text, and then save it in the HelloWorldWeb directory: web.config

<configuration>
  <system.runtime.remoting>
    <application>

      <service>
        <wellknown mode="SingleCall">
                   type="HelloWorldObject.Hello, HelloWorldObject" 
                   objectUri="SimpleHelloWorld.soap" />
      </wellknown></service>

    </application>
  </system.runtime.remoting>
 </configuration>

5) Click Start, point to Programs, and then click Administrative Tools. Open Internet Services Manager.
6) Create a virtual directory in IIS.
7) Make the virtual directory alias SimpleHello, and then set the source directory to the HelloWorldWeb directory.


Build a Simple Console Application to Test the Remote Object

TestClient.cs(Console application)

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Services;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;

using HelloWorldObject;

namespace Client
{
	class TestClient
	{

		[STAThread]
		static void Main(string[] args)
		{
			HttpChannel http = new HttpChannel();
			ChannelServices.RegisterChannel(http);

			Hello obj = (Hello)Activator.GetObject(typeof(Hello),"http://localhost/SimpleHello/SimpleHelloWorld.soap");
			Console.WriteLine(obj.HelloWorld("CLIENT APPLICATION"));
		}
	}
}

Add references to the following:
1) System.Runtime.Remoting
2) HelloWorldObject.dll (by browsing to the location of the .dll file)
