Windows 2003 FTP ban scripts

Anyone who admins a Windows 2003 server with FTP access that must be opened to all ( e.g shared web hosting server ) will have encountered brute force FTP logins to the server. If you are using FTP via IIS ( which as shit as it is, is sometimes the only option ) then you will be very interested in the great scripting work by other bloggers.

Below are some links to excellent FTP ban scripts.
