The problem is simple. Running a php file in browser vs command line produces very different results and I can't for the life of me figure out why. Any php/psexec experts out there run into this before?

<?php

echo '<pre>';
$output = shell_exec("psexec -accepteula \\\mypcname -u mypcname\\accountname -p xxxxxxx ipconfig /all 2>&1");
var_dump($output);
echo '</pre>';

Produces this output in a browser window...

Connecting with PsExec service on admin-pc...


Starting ipconfig on admin-pc...


ipconfig exited on admin-pc with error code 0.

Instead of this, which is the output I get when running the same php file via command line.

  • I think it's because when you're running via command line, you're not elevated. However, your webserver is an administrator. Try creating a new shortcut to cmd.exe, and running that as an administrator to run your PHP. – Dave Chen Oct 14 '14 at 02:00
  • Hmm was a good suggestion but I get the same results =\ – Skej Oct 14 '14 at 02:50
  • Can you try the same thing but using `php.exe` instead of `php-cgi.exe`? – Dave Chen Oct 14 '14 at 02:52
  • Some more info to digest, I know that psexec is executing the command properly on the remote pc because I can tweak the line in php and launch notepad, calculator etc on the remote pc It's just the stdout or stderr that's not reaching the browser. – Skej Oct 14 '14 at 02:54
  • Same results with php.exe – Skej Oct 14 '14 at 02:56
