Hi Folks,
   Here's the conclusion to my sshd journey.  Larry was correct.
When installed properly, sshd should "just work", even using keys & with
multiple users.
Here's an exact record of the process I used for those considering embarking
on this journey
for themselves.  :-)

thanks & best regards,
eric

6.  Execute ssh-host-config.

    $ ssh-host-config -p <PORT> -c 'ntsec tty'

    Generating /etc/ssh_host_dsa_key

    Privilege separation is set to yes by default since OpenSSH 3.3.
    However, this requires a non-privileged account called 'sshd'.
    For more info on privilege separation read
/usr/share/doc/openssh/README.privsep.

    Should privilege separation be used? (yes/no) yes
    Warning: The following function requires administrator privileges!
    Should this script create a local user 'sshd' on this machine? (yes/no)
yes
    Generating /etc/sshd_config file
    Added ssh to C:\WINNT\system32\drivers\etc\services
    Added ssh to /etc/inetd.conf


    Warning: The following functions require administrator privileges!

    Do you want to install sshd as service?
    (Say "no" if it's already installed as service) (yes/no) yes

    The service has been installed under LocalSystem account.
    To start the service, call `net start sshd' or `cygrunsrv -S sshd'.

    Host configuration finished. Have fun!

8.  Restart Win2K/SP4 machine.
9.  Confirm cygrunsrv/sshd processes are running via Windows Task Manager.
10. Execute 'ssh -p <PORT> 127.0.0.1'.
    Eric@<HOSTNAME> ~
