PHP Question

PHP exec() command not executing

After hours and hours of trying and searching for an answer i coudn't get it working.

Hosting details:

Windows Server 2012 R2

Plesk 12

IIS 8.5

The problem



My problem is:
I want to execute this command in PHP. The command is necessary to reload the configs for filezilla, after creating a new user with an PHP script.

C:\Program Files (x86)\FileZilla Server\FileZilla Server.exe /reload-config


It does work when i try it directly in CMD.
But in PHP if doens't somehow work. I tried so many things, that im going to try to give you all the manners i tried.

I tried to do this at the following ways:

Trial 1



$command = '"C:\\Program Files (x86)\\FileZilla Server\\FileZilla Server.exe" /reload-config';
exec( $command, $output, $return);

print_r($output);
echo '<br/>' .$return;


Output:

Array ( )
0


Trial 2



$command = '"C:\\Program Files (x86)\\FileZilla Server\\FileZilla Server.exe" /reload-config';
system( $command, $output);

print_r($output);


Output:
0


Trial 3



$command = 'C:\\"Program Files (x86)\\FileZilla Server\\FileZilla Server.exe" /reload-config';
exec( $command, $output, $return);

print_r($output);
echo '<br/>' .$return;


Output:
0


Trial 4 (The only one that returns an error!)



exec( 'C:\\"Program Files (x86)\\FileZilla Server\\FileZilla Server.exe" /stop 2>&1', $output);
print_r($output);


Output:

Array ( [0] => Toegang geweigerd. )


In english:

Array ( [0] => Access denied. )


Privileges:



In allmost all awnsers found they talked about privileges. I did following privileges:

Gave all web users and IUSR privileges to CMD.exe and FileZilla Server.exe,
and tried to set the IIS authentication from anonymous to an Administrator account

Somebody said to try this:

echo '<pre>';
system('set', $retval);
echo ' </pre>';


If i do that my output is: http://pastebin.com/SjzeQpJ0

If you guys want anymore details just ask. I hope you guys can figure it out for me. I tried to be as clear as possible. Thanks.
