IIS is the windows web server service that runs web-pages.
How to execute shell scripts
Should the web-page refuse to execute some command-line script, then it is likely that the "cmd.exe" doesn't has permissions for the IIS user session to access it. Here's how to fix it:
- Right-click "cmd.exe" from the windows folder on Properties.
- Select security --> add --> advanced --> locations --> choose the computer --> type 'IUS' --> check names --> select "IUSR_MACHINE" --> Enable Read/Execute permissions --> Apply/Ok --> close.
- Restart the IIS service.
