PHP works fine under IIS...I can run the phpinfo(); function just fine.  MySQL works fine.  I can go into MySQLAdmin and add tables, etc...

When I try and run the script
<?
  $db = mysql_connect("localhost", "root");
  if($db)
    echo("Success");
  else
    echo("Failure");
?>
through IIS, it fails with a timeout error message.

However, if I run this same script through the command line (eg. php.exe index.php) it returns Success in a fraction of a second.

I have given USR_compname full rights to c:\mysql, c:\php, c:\src (which is where the .php is located) and c:\winnt\system32.

IIS has a virtual directory called ComicReader that points to c:\src\comicreader.  
.php files map to c:\php\php.exe %s %s and Script Engine is checked.

I am running php cgi v4.0.6 from the php-4.0.6-Win32.zip.
