Good eye. That is probably the magic button for Brian's problem.

My magic button turned out to be, er, um, reinstalling SP6a. I had
installed VPN after installing SP6a, and needed to reinstall SP6a to
update. I'm now making encrypted connections from NT.

BTW, one thing that does not work: Microsoft's
windowsupdate.microsoft.com site. It's a pretty clever approach to
updates (for Microsoft, anyway :-), but it doesn't catch the sort of
problems that are solved by reinstalling a service pack.
