Then West Wind Web Monitor is the tool for you. Web Monitor can help you monitor any number of Web site links to ensure they are alive and kicking, and more importantly, returning the results you actually expect. Web Monitor can watch an unlimited number of Web site Urls and notify you via email or pager if and when there is a problem. It can even launch another URL or execute a file to correct the problem without manual intervention when a failure occurs. Web Monitor also notifies you again once the site comes back up, so that you can relax and back off from full panic mode at 3am in the morning.

Web Monitor can run either as a desktop application, taskbar item or as a Windows Service and allows you to monitor up to 100 sites per instance. The Service Version also provides a remote Web interface to administer the Web Monitor Service over the Web (requires Internet Information Services and ASP.NET 2.0 or later).
