Somebody else can probably verify that this is true or not, but I believe
that on an unpatched server, that request would root IIS and the request
would never get logged.
It's probably not the best idea to consider yourself safe based off this,
but I would have admins consider this, especially since many will read their
IIS logs hoping to detect break-ins. : )
