server problems for exec functions

[DorkRawk]

I'm pretty sure that my command line execution functions are correct, but when I put them on my page it wont load. What kind of server problems might cause this (I already have safe_mode off)????

<?php  

//ini_set("allow_url_fopen", 1);


echo ("<br><br><br>");
echo ("UNIX time= ".time());
echo ('<H1>List of links</H1>');

//$command = "\cmd.exe";


//system('c:\\WINNT\\system32\\cmd.exe ');
//$outstring=system('jlt.txt');

//phpinfo();

//echo("<pre>$outstring</pre>");
//echo("changes made**** <br>");

//phpinfo();



$url = "google.com"; 
$filename = "jlt.txt"; 

$dir_output = `dir "c:\" `;           // directory listing 
$ping_output = `ping "$url" `; 
$trc_output = `tracert"$url" `; 
$type_output = `type "$filename" `;   // text file contents 

echo "<pre>"; 

echo "$dir_output <br> 
          $ping_output <br> 
          $trc_output <br> 
          $type_output";

// Copy file data into a string

$filestring=file_get_contents("jlt.txt");

//$teststring=file_get_contents("jlt.txt");
//$pagehand=fopen("page.txt", "w");
//fwrite($pagehand, $outstring);
//fclose($pagehand);


$pos1=strpos($filestring, 'label type "');
if($pos1===FALSE){ echo ("Error in reading folder");}
