Sometimes you need to restart IIS (for example the last shutdown of World Wide Web Publishing Service locked on "stopping") and you really can't or don't want to reboot the server. Microsoft provides a utility called iisreset (located in winnt\system32). That should be in your $path so you don't really need to know that.

Simply open a "dos command prompt windows" and type iisreset /stop and then iisreset /start
