As expected, here's Microsoft's reply to my note to secure at microsoft.com.

Thanks very much for your note. However, it sounds as though the issue
you've reported is a technical support issue rather than a security
vulnerability in a Microsoft product. As much as we wish we could
provide technical support, Microsoft Product Support Services is the
better place to go for this kind of assistance. Information on how to
contact PSS is available at http://www.microsoft.com/support/. The IIS
Lockdown tool is supported.
