Please KHCZ> help me.:) While you can call shutdown directly from exec - some things are best not called like this. PHP will be left hanging waiting for the process to finish, so you'll get a really nasty shutdown going on without properly ending your sessions. You'd be better off looking at COM scripting it to be honest. Or write a Windows application that does what you require (closes down all services smoothly, reboots, etc) and exec that, providing your IIS user has the correct permissions to do so. The warning most likely comes from IIS, or your php.ini settings - I just tested "shutdown -i" on Apache (in WinXP) and it ran without any problems.
