trying to use EXEC with Zend

I want my PHP script to run a DOS command on the PC whose browser opened
the script, It looks like EXEC should do this, but no matter what
command I use - including easy stuff like DIR or IPCONFIG - I get a "file
not found" message. For example, if the script contains

$test= exec('dir 2>&1', $output);
echo $test;
echo '<BR>';
var_dump($output);

I get

sh: dir: not found.
array(1) { [0]=> string(20) "sh: dir: not found." }


Any ideas?
