Thanks again for responding so quickly.  My quick test did not work, but perhaps I misunderstood.
I did the following:
- Set "passwd -R" to blank value
- Download, but not install, http://cygwin.com/snapshots/x86/cygwin-inst-20130729.tar.bz2
- Extract /bin/cyglsa*.dll from the snapshot, overwriting the existing files
- cp /bin/cyglsa.dll /bin/cyglsa/, since this is a 32-bit OS
- Do not reboot, or run cyglsa-config, or anything else

ssh niven (using pub key)
$ set | grep USER
USER=gessh
USERDOMAIN='NT AUTHORITY'
USERNAME=SYSTEM

Did I miss a step, or should I try something more aggressive?

Thanks!
