Hur gör man det??

Alltså en intern webbserver i ett AD nätverk?

Kolla om detta kan vara något..

    }
    echo 'ip : '.$ip.'<br>';
   
    /* send a "special" packet */
    $fp = fsockopen('udp://'.$ip, 137);
    fwrite($fp, "\x80b\0\0\0\1\0\0\0\0\0\0 CKAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\0\0!\0\1");

    /* wait 2 secs, and get the data */
    socket_set_timeout($fp, 2);
    $data = fread($fp, 256);
   
    /* get netbios records number */
    $nbrec = ord($data[56]);
   
    /* display nebios records : the username is a record of type 3 */
    echo '<table border="1">';
    echo '<tr><th>no</th><th>type</th><th>value</th></tr>';
    for($i = 0; $i < $nbrec; $i++) {
     $offset = 18 * $i;
     printf ("<tr><td>%02d</td><td>%02X</td><td>%s</td></tr>",
         $i,
         ord($data[72 + $offset]),
         trim(substr($data, 57 + $offset, 15)));
    }
    echo '</table>';
?>

hmm gick inte så bra men man kanske då ska köra ASP på IIS??
