I believe so.  I read the above as "one only needs to change /etc/passwd
and /etc/group if the machine is part of a domain".  Perhaps it could be
reworded to make that clearer -- <>.

Your Administrator user is probably not seeing /usr/sbin, or the
permissions on /usr/sbin are wrong.  Hard to know without more

I don't recall you attaching the output of "cygcheck -svr" as requested in
<>.  Please provide that information so
that we know what you have on your Cygwin installation.  Also, if you log
in as Administrator, can you explicitly run /usr/sbin/sshd?  If not, what
is the error message?
