So my understanding is that Wyden's staff has been bothering the company about this class of vulnerabilities for a while, and the recent recommendations (a blog post explicitly cited in my post) are one output of that.
But I don't really accept this explanation. I always understand that there are legacy deployments and Microsoft needs to support them, but Kerberos-misconfiguration issues are extremely subtle in their implications, and MS should understand that one blog post (or some knowledge base articles) isn't going to get the message across to the hundreds/thousands of AD admins whose networks are currently at risk.
What I think recent versions of the MS software could do: (1) automatically scan configurations for accounts set up this way, (2) be incredibly annoying about changing the configuration (there are a handful of ways to do this that should be workable for many legacy configurations). If admins want to override the annoying and explicit warnings, that would be on them and not MS. As far as I can tell, Microsoft isn't doing this. But if I'm wrong, please let me know.
