Will do the next time I see this...too bad I didn't see your e-mail earlier this morning, as I had another recurrence today after a windows-update-forced-reboot.

I'll remove those dependencies for now to aid in debugging.  I can add them back later.

I had not.  Somehow I'm not surprised that we have "historical junk" in our AD, and (of course) I don't have access to do any cleanup.

> Still, some debugging on affected systems might be enlightening.

I'll be happy to do anything of interest.  As a starter, I'm going to see if I can figure out which of my SIDs are being used by the couple of file shares I routinely access from cygwin.
