How to get the Client System Mac-id and other details like IP Address etc

Question

In web project I have a Page which fetches the Local System Mac-id and other values such as processorid etc,for that I have used the below code.It worked perfectly during Development in the Localhost but when we had published the website and now use the same page to fetch the details,it is fetching the details of the Web Server.Is there any alternate way to fetch the Local Machines details.Kindly any one help.

The code I ued for Fetching System details is,

  #region Sytem Details
    private string GetMac()
    {
        string Mac = string.Empty;
        ManagementClass MC = new ManagementClass("Win32_NetworkAdapter");
        ManagementObjectCollection MOCol = MC.GetInstances();
        foreach (ManagementObject MO in MOCol)
            if (MO != null)
            {
                if (MO["MacAddress"] != null)
                {
                    Mac = MO["MACAddress"].ToString();
                    if (Mac != string.Empty)
                        break;
                }
            }
        return Mac;
    }



    public static string LocalIPAddress()
    {
        IPHostEntry host;
        string localIP = "";
        host = Dns.GetHostEntry(Dns.GetHostName());
        foreach (IPAddress ip in host.AddressList)
        {
            if (ip.AddressFamily.ToString() == "InterNetwork")
            {
                localIP = ip.ToString();
            }
        }
        return localIP;
    }

            return item.Properties["Name"].Value.ToString();

        return "Unknown";
    }



    private string GetProcessorID()

        {
            //*** Only return cpuInfo from first CPU
            if (sCpuInfo == String.Empty)
            {
                sCpuInfo = objMgtObj.Properties["ProcessorId"].Value.ToString();
                bSuccess = true;
            }
        }

Edit

It may not be over the Internet because the User is going to register the System,so he/she only gets the details and registers,so is there any way of Automatically getting the users PC data from his end in Just a Click of a button.

Over Internet you can't fetch Mac Address of client machine if the device/system comes after a router in Network, though if your application is an Intranet application you can first get the IP address of client and then apply an ARP to get the mac ID of client device/machine. I have done this for one of my projects to get the mac ID of client's device but I have used a DHCP read for the same.
