curl

I followed http://stackoverflow.com/questions/724107 to login to wordpress, using php_curl, and it works fine as far I use WAMP, (apache/php).

But when it comes to IIS on the dedicated server, it returns nothing.

I have wrote the following function which is working fine on my local wamp, but when deployed to client's dedicated windows server 2k3, it doesn't. Please help me

function post_url($url, array $query_string)
    {
        //$url = http://myhost.com/wptc/sys/wp/wp-login.php
        /*      $query_string = array(
                            'log'=>'admin',
                            'pwd'=>'test',
                            'redirect_to'=>'http://google.com',
                            'wp-submit'=>'Log%20In',
                            'testcookie'=>1
                        );
        */

        //temp_dir is defined as folder = path/to/a/folder
        $cookie= temp_dir."cookie.txt";


        $c = curl_init($url);



        if (count($query_string))
        {
            curl_setopt ($c, CURLOPT_POSTFIELDS, 
                http_build_query( $query_string )
            );

        }

        curl_setopt($c, CURLOPT_POST, 1);
        curl_setopt($c, CURLOPT_COOKIEFILE, $cookie);
        //curl_setopt($c, CURLOPT_SSL_VERIFYPEER, 1);
        //curl_setopt($c, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
        curl_setopt($c, CURLOPT_TIMEOUT, 60);
        curl_setopt($c, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); //return the content
        curl_setopt($c, CURLOPT_COOKIEJAR, $cookie);
        //curl_setopt($c, CURLOPT_AUTOREFERER, 1);
        //curl_setopt($c, CURLOPT_REFERER, wp_admin_url);
        //curl_setopt($c, CURLOPT_MAXREDIRS, 10); 

        curl_setopt($c, CURLOPT_HEADER, 0);
        //curl_setopt($c, CURLOPT_CRLF, 1);


        try {
            $result = curl_exec($c);
        }
        catch (Exception $e)
        {
            $result = 'error';
        }

        curl_close ($c);

        return $result;  //it return nothing (empty)
    }

Other Facts

curl_error($c); return nothing
when header CURLOPT_HEADER is set to ON, it return this header
