I run a website on Windows Server 2008 R2. Looking through the IIS logs, I have noticed that there are some IP addresses repeatedly requesting certain URLs (such as for example /mysql/phpmyadmin/main.php, /phpadmin/main.php) which do not exist, as the site is entirely served off of ASP.NET. They are obviously fishing for known vulnerabilities.

My question is, are there any firewall or other tools (Windows built-in or commercial) that allow me to block those IP addresses which request certain URLs multiple times?
