  Thanks for pointing out Ralph. Oops...I guess they were correct.
  My method works only on a local machine.
  
  For a remote machine, the only way is to use the ARP cache - but I dont think it can be done from ASP.NET.
  
  If you type a ARP -a at command prompt it shows the remote hosts connected and their MAC Address. But I dont think its possible to access that data from ASP.NET

  Hi,
  
  This should work once you have the IP Address:
  
  protected string GetMACAddressByIP(string ip)
  {
  try
  {
      System.Management.ManagementObjectSearcher query= new
  System.Management.ManagementObjectSearcher("SELECT * FROM
  Win32_NetworkAdapterConfiguration");
      System.Management.ManagementObjectCollection queryCollection = query.Get();
          
      bool Found = false;
  
      foreach(System.Management.ManagementObject mo in queryCollection)
      {
          if(mo["IPAddress"] != null)
          {
                          
              string temp;
              temp = string.Join(".",(string[])mo["IPAddress"] );
              if(!temp.Equals(""))
              {
                  if(!ip.Equals(""))
                  {
                      if(temp.Equals(ip.Trim()))
                      {
                          Found = true;
                      }
                  
                  }
                  else
                  {
                      Found = true;
                  }    
              }    
                          
              if(Found == true)
              {
                   if(mo["macaddress"] != null)
                   {
                      if(!mo["macaddress"].Equals(""))
                      {
                          return (string)mo["macaddress"];
                      }
                   }
              }
              else
              {
                  Found = false;
              }
  
          }
      }
  
      MessageBox.Show("No Mac Address Found");
      return "";
      
  }
  catch(Exception ex)
  {
      MessageBox.Show(ex.Message);
      return "";
  }
  }

  yes i was going to point this out
  
  I could shell it out but i dont want to have to do that as it is unprofessional.
  
  Ok, what about using client side scripting on the page, like vbscript or javascript
