Sample scripts are provided as-is with no warranty of fitness for a particular purpose. These scripts are solely intended to demonstrate techniques for accomplishing common tasks. Additional script logic and error-handling may need to be added to achieve the desired results in your specific environment.

This script monitors a local IIS web site and automatically restarts the World Wide Web Publishing Service if the site is unavailable. If restarting the WWW service does not resolve the problem then this script runs a full iisreset /restart

This sample shows how to use LOOPCOUNT and LOOPTO to implement a retry loop that allows a specified number of errors before failure. It also illustrates the use of DOSCMD to restart a service. The script logic was written as a big loop so you can use the Robo-FTP Service Installer to run this script as a Windows Service so it will constantly monitor the local website and automatically restart if the computer is rebooted.

Note: This script must be run by a user account with permission to restart IIS.
