php exec doesnt works on iis

I got a windows dedicated server with hostgator, there Im trying to add a exe script that receive some variables and after his process ends returns some result that the php page get and print, like this:

http://www.pvtcloudlab.com/test10.php

<?php
exec("files\\solver.exe 0 1 2 3 4 2>&1",$out,$exitcode);
echo "<br />EXEC: ( exitcode : $exitcode )";
echo "<hr /><pre>";
print_r($out);
echo "</pre>";

$output = shell_exec("whoami");  
echo "<pre>$output</pre>";
?>

Select allOpen in new window

But no matter what config i change I allways get the following error:

EXEC: ( exitcode : 1 )

Array
(
    [0] => This program is blocked by group policy. For more information, contact your system administrator.
)

Select allOpen in new window

From the screens "iie-screen1.jpg" to "iie-screen5.jpg" its all changes that I do in IIS

And also this is my web.config file that im using on this site:

Thinking that maybe the problem was about the users and his permissions i add this two lines add the end of the test

$output = shell_exec("whoami");  
echo "<pre>$output</pre>";

Select allOpen in new window

to see who is the owner of the process, that result was "pvtc\iwpd_1(pvtadmin)", thats way I add him all permissions to the folder where i got the script(iie-screen6.jpg and iie-screen7.jpg).

Before to change the domain to the windows dedicated server with hostgator, I had my page pointed to another windows dedicated server where i has the page using xampp and all works without a problems
link: http://201.159.192.204/test1.php

<?php
  $salida = array();
  exec("C:\\inetpub\\vhosts\\pvtcloudlab.com\\httpdocs\\solver.exe 0 1 2 3 4",$salida);
  echo $salida[0]; 
?>

Select allOpen in new window
