Running as a user with Administrator privilege is not sufficient. Is the parent process running as root or setuid to root?

You should not be calling system(3), and most especially you should not be calling it from a process running as root. Please consult your copy of "Advanced Programming in the Unix Environment" by W. Richard Stevens, and see his straightforward examples on the correct usage of fork(2) and execv (2), which will do what you want just fine. Incidentally, unless you are shutting the system down in an emergency, invoking shutdown(8) may not be the correct way to bring the system down. It's definitely not polite to any currently-logged- in console user. This email sent to site_archiver@lists.apple.com
