Hi All I am facing prob in UDP Broadcasting using C#. I am using 2 pc connected in LAN.Please Help

Hi
I am trying to broadcast(UDP) a message on LAN using C#.I have connected systems(P2P connection).I am able to send and receive broadcast message on 1st pc but unable to see the same result on 2nd pc.Please Help

My code is

For Receiving Broadcast Message..
soc = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
IPEndPoint iep = new IPEndPoint(IPAddress.Any, 9999);
soc.Bind(iep);
EndPoint ep = (EndPoint)iep;
soc.EnableBroadcast = true;


byte[] buffer;
while (true)
{
buffer = new byte[1024];
soc.Receive(buffer);
string bufferstr = null;
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
bufferstr = enc.GetString(buffer);

}

For Broadcasting Message...
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
sock.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1);

IPEndPoint iep = new IPEndPoint(IPAddress.Broadcast, 9999);
string message;

byte[] data = Encoding.ASCII.GetBytes(message);
sock.EnableBroadcast = true;
sock.SendTo(data, iep);
Thread.Sleep(3000);
sock.Close();
