Ping BSOD

Hi,

I am trying to make a program that is going to ping through my LAN.

I have the following code:



using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.NetworkInformation;

namespace ScanLAN
{
  public partial class frmScan : Form
  {
  public frmScan()
  {
  InitializeComponent();
  }

  private void frmScan_Load(object sender, EventArgs e)
  {
  for (int subnet = 1; subnet < 254; subnet++)
  PingLAN("192.168.1." + subnet);
  }

  private void PingLAN(string IP)
  {
  try
  {
  Ping pingSender = new Ping();
  PingOptions options = new PingOptions();
  options.DontFragment = true;
  string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
  byte[] buffer = Encoding.ASCII.GetBytes(data);
  int timeout = 120;
  PingReply reply = pingSender.Send(IP, timeout, buffer, options);
  if (reply.Status == IPStatus.Success)
  {
  Console.WriteLine("Address: {0}", reply.Address.ToString());
  Console.WriteLine("RoundTrip time: {0}", reply.RoundtripTime);
  Console.WriteLine("Time to live: {0}", reply.Options.Ttl);
  Console.WriteLine("Don't fragment: {0}", reply.Options.DontFragment);
  Console.WriteLine("Buffer size: {0}", reply.Buffer.Length);
  }
  else
  {
  Console.WriteLine(IP + " - No Reply");
  }
  }
  catch (Exception ex)
  {
  MessageBox.Show(ex.Message);
  }
  }
  }
}




The problem is, if I press the stop debugging button while it is running, most of the time my computer crashes to a BSOD. Does anyone know why this is happening and how I can sort it?
