.Net Remoting Problem. NOt working over LAN or Internet

[ankitpsaraogi]

This is the form.cs in my REMOTE SERVER

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using Microsoft.Win32;


namespace remoteserver
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{

TcpChannel ch = new TcpChannel(8085);

ChannelServices.RegisterChannel(ch);

RemotingConfiguration.RegisterWellKnownServiceType(typeof

(remoteclass.xx), "Ankit", WellKnownObjectMode.Singleton);

}
}
}

And This code is present in my Remote Client
It returns the sumation of two numbers in textBox1 and textBox2 in textBox3

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Runtime.Remoting;

using System.Runtime.Remoting.Channels;

using System.Runtime.Remoting.Channels.Tcp;
using System.Runtime.Serialization.Formatters.Soap;
using System.Threading;



namespace remoteclient
{

public partial class Form1 : Form
{


remoteclass.xx obj = new remoteclass.xx();

public Form1()
{

InitializeComponent();

}





private void button1_Click_1(object sender, EventArgs e)
{
try
{

obj = (remoteclass.xx)Activator.GetObject(typeof(remoteclass.xx),

"tcp://"+txtPath.Text+":8085/Ankit");

int x = Int32.Parse(textBox1.Text);

int y = Int32.Parse(textBox2.Text);

textBox3.Text = (obj.sum(x, y)).ToString();
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}


My REMOTE CLASS

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Drawing.Imaging;
using System.Runtime.Remoting;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Soap;
using System.Runtime.InteropServices;
namespace remoteclass
{


public class xx : MarshalByRefObject
{

public int sum(int a, int b)
{

return a + b;

}
}
}




when I input localhost in txtPath
it works great


But when I try to connect it over lan
(Say my ip address is 192.168.1.1 and the server's ip address is 192.168.1.2)
and i input 192.168.1.2 in txtPath

I get the System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not respond after a period of time, or established connection failed because connected host has failed to respond 192.168.1.2

and when i try it over the internet
I get the exception
"No connection could be made because the target machine actively refused it."





Thanks in advance
