We host numerous ftp sites on a single Windows 2003 server (using IIS and Active Directory to manage the sites and users).
One of the sites is public (unrestricted), but we have a bot that's been uploading index.php/index.html/.htaccess files every day.
Since it's a public site, there's nothing really there that can be comprimised, but it's annoying to have to flush these files every day. Is there a way to restrict uploads by filename?
