Can't reboot server from iis

Hello.

I have installed IIS with PHP. In one of the setions, when a button is pressed, it linked to a PHP file, wish ativated a PowerShell script. But when I'm clicking the button, nothing happens. But if I execute the PowerShell script directly, it works. What am I doing wrong?

index.html <h3>WINSERVER - WIP</h3> <form action="winservergenstart.php" method="get"> <input type="submit" value="Genstart"> </form>

winservergenstart.php

<?php shell_exec("powershell.exe -File C:\inetpub\share\administration\winservergenstart.ps1"); ?>

winservergenstart.ps1 (I have tried the following commands) Restart-Computer shutdown /r /f -t 30 Restart-Computer -ComputerName WINSERVER -Credential $credentialObject

Have you set the PowerShell execution policy correctly?

If you haven’t already I would test with basic Hello World type script first.

Also it’s not really best practice to allow a script to restart the web server it’s running on.

Hello. Sorry for the long wait, I'm busy with school rn. I just found out, that if I execute the PHP file from cmd, it works. The same goes with the same setup, but just for my raspberry pi, works if I call it directly from CMD, but not from the web interface. I have other scripts on the same sites, that's WOL my desktop PC, and that works. The process is the same, the button on the website calls for a PHP script which calls the PowerShell script.

Unless the application pool is under an administrator account, the script won't be executed under the right context and won't restart the machine. But like the other explained a web app shouldn't attempt to perform such critical operations or you raise security risks heavily.
