Status: Feedback

Box is behind a company firewall so you can unfortunately not access
it.
This is an intranet site.

This is what I ran:
<?php
echo exec('c:\Windows\System32\whoami');
?>
ProcMon shows cmd.exe being started by php-cgi.exe
A thread is created running as the correct user.
Excecuted command is: cmd.exe /c "c:\Windows\System32\whoami"
I do notice that the process exits with Exit Status 5, which is normally
access denied.
I have however already tried to give Everyone full access to the whole
machine, i.e. all drives. Still the same error.

btw, is it possible to access this box? I could try to debug what's
wrong there as it works just fine with the same constellation here (same
windows, IIS and fcgi versions).

It is not the same context using runas or impersonate.
Did you use "c:\\....\\whoami" or "cmd /c..."?

BTW if I run the same script on the webserver using fakeCGI and runas to
run as the application pool user it works.
Fake FastCGI web server
FCGI_PARAMS sent
FCGI_STDIN sent
Launching receive loop
FCGI_STDOUT: X-Powered-By: PHP/5.3.2
Content-type: text/html; charset=utf-8
Hello World!"
FCGI_END_REQUEST received
killing app
FastCGI process exited with 0
So the problem is definitely in the combination IIS6 and PHP 5.3
