The folks at Applicure, the dotDefender vendor, have created WebTuff, a free utility to check for the IIS 6 WebDAV vulnerability.
I occasionally run into dotDefender when I'm "analyzing" web application security issues on the Intarweb, and can say that I've been pleasantly surprised by its capabilities.
Please note: This is not an endorsement for Applicure products; simply consider it the suggestion that they are worthy of your consideration.
To that end, a free utility is always a great way generate interest; if your're concerned about exposure to the WebDAV vulnerability, give WebTuff a try.
