If you can suggest a test for this, I'd be happy to run it for you.
I've reached my limit as far as specific ideas, though I will happily
follow instructions.

Yes; the general summary was:

* my /etc/groups file was created by mkgroup in the usual way and I
  see no obvious error there (subject to correction by other
  eyeballs), and

* I do indeed have Symantec AntiVirus installed.  Can't change it,
  since it's locked down by IT.  However, the log files show it hasn't
  triggered on anything in weeks, which is how old this computer is.

By "README", do you mean /usr/share/doc/Cygwin/rebase-2.4.3.README?
That tells me to:

(1) Shut down all Cygwin apps/services (of course I have no services,
    since launching a service is the problem, but I checked anyway)

(2) Start an ash shell: I started a DOS shell and then typed "ash" in

(3) Run /bin/rebaseall.

Ok, did that.  (Well, forgot a bash shell running under Emacs the
first time, but got it the 2nd time.)

Now let's try running cron-config again... still screwed the same way:

  >Do you want to start the cron daemon as a service now? (yes/no) yes
  >cygrunsrv: Error starting a service: QueryServiceStatus:  Win32 error 1053:
  >The service did not respond to the start or control request in a timely fashion.

I'm gonna need a bit more guidance here; I found this script:

... but need a little more instruction about how to provoke a fork
failure.  Like, what exactly would you like me to type at this SYSTEM
owned shell?

(And the use of "at" in sysbash is pretty entertaining, I gotta admit... :-)

I have the latest version as of this morning, which is the last time I
ran setup.exe.  If it's changed since then, I'll get it tomorrow
morning. :-)
