mysql_errno() on IIS

Please advise. I keep getting the following error when I try to test MySQL on IIS4.

This is the script I run:

<?php
$host="localhost";
$user="admin";
$password="1234";
mysql_connect($host,$user,$password);
$sql="show status";
$result = mysql_query($sql);
if ($result == 0)
echo("<b>Error " . mysql_errno() . ": " . mysql_error() . "</b>");
elseif (mysql_num_rows($result) == 0)
echo("<b>Query executed successfully!</b>");
else
{
?>

AND THIS IS THE ERROR I RECEIVE:


Error " . mysql_errno() . ": " . mysql_error() . "</B>"); elseif (mysql_num_rows($result) == 0) echo("Query executed successfully!"); else { ?> Variable_nameValue
