Dawa,
I used this method in 1.1:

using System ;
using System.Runtime ;
using System.Runtime.InteropServices ; 
public class InternetCS
{
  [DllImport("wininet.dll")]
  private extern static bool InternetGetConnectedState( out int Description, int ReservedValue ) ;

  public static bool IsConnectedToInternet( )
  {
    int Desc ;
    return InternetGetConnectedState( out Desc, 0 );
  }
}

If you don't want to use "old" DLLs and stay with managed code you could us the new Ping class introduced in 2.0. You could try to ping a server that is "always" up (like cnn.com or levelextreme.com). I looked briefly at the Ping examples in the M$ docs and the examples look good.

HTH,
Einar
