[PHP]Telnet werkt niet

[Verwijderd]

Ik probeer via PHP een telnet sessie op te zetten echter het scripje wil niet werken
Ik krijg na een tijdje een error: Maximum execution time of 30 seconds exceeded

Ik probeer vanaf een PHP website (welke op een windows server draait) een service te starten/stoppen van een windows machine.
Als ik gewoon een telnet sessie open en het commando sc start servicenaam geef dan wordt de service naam echt gestart. Echter via het PHP script gebeurd er niets.

Dit is het script:

PHP:

class PHPTelnet {
    var $use_usleep=0;  
    var $sleeptime=125000;
    var $loginsleeptime=1000000;
    var $fp=NULL;
    var $loginprompt;

    function Connect($server,$user,$pass) {
        $rv=0;
        $vers=explode('.',PHP_VERSION);
        $needvers=array(4,3,0);
        $j=count($vers);
        $k=count($needvers);
        if ($k<$j) $j=$k;
        for ($i=0;$i<$j;$i++) {
            if (($vers[$i]+0)>$needvers[$i]) break;
            if (($vers[$i]+0)<$needvers[$i]) return 4;
        }
        
        $this->Disconnect();
        
        if (strlen($server)) {
            if (preg_match('/[^0-9.]/',$server)) {
                $ip=gethostbyname($server);
                if ($ip==$server) {
                    $ip='';
                    $rv=2;
                }
            } else $ip=$server;
        } else $ip='127.0.0.1';
