I have some PHP scripts that reside on a network share. For argument's sake, let's call the share \\nas\dev. I have a Web Site on \\w2k3dev\ set up in IIS6 that uses \\nas\dev\ as its home directory by setting "A share located on another computer".
Some of my scripts use shell_exec to execute functions on the server and return results to my script. Again for argument's sake let's say I'm just getting a directory listing like so:
echo shell_exec('dir');
- If I run the script in IIS, I get no output - but no error logs either.
- If I set up Apache on
\\w2k3dev\and configure it to use the same share, the script runs fine - If I copy the script to the local machine and run it through IIS it works fine.
So the problem only seems to be when IIS is set up to use a network share with a script containing shell_exec. Every other aspect of my scripts work fine.
Profiling in procmon, I can see that cmd.exe operates completely differently depending on whether it's being run by IIS or Apache. I have more details, but for the sake of being concise, I will omit them for now unless someone asks for more details.
Thank you so much for looking at this, I am at my wits end.
Kind regards
