Using taskkill with php

Question

I work on a Web-Panel to start and end programs on my Windows Server.

The server is a dedicated server with Windows Web Server 2008 R2 and Plesk Panel.

My php code:

taskkill /F /IM Gotcha_Antihack.exe 2>errors.txt
pclose(popen($cmd, "r"));

Text from the errors.txt:

FEHLER: Zugriff verweigert. (Error: access denied)

Can't I execute the taskkill (permissions for the Internet User are granted) or can't the taskkill end the process (the same user start the process)?

Answer 1

The Problem was about the Windows User Account Control. I have to give the ISS User the rights for the command.
