lol .. I guess ppl are just lazy.

Well I'm guessing the site uses basic authenticaion, and if they're running Apache servers try getting ahold or .htaccess/passwd files, if their running IIS there's little chance of getting access to the NT Authentication dbase. Other than running a brute force, you'd have to run some pen-tests, see whats running and ports are open. Use eEye Retina, or Nessus, or some sort of vulnerability scanner and try to find an exploitable service.
