I ran into some ssh(d) related problems when I migrated laptops (older
ssd w/ Cygwin32 on Win7 migrated to an almost identical build but
fresh install of Win7 on a larger SSD) and copied all of my Cygwin
stuff over w/o re-installing. My problem was that sshd would start but
I could never connect to it.

AFAIK, /var/empty should be owned by cyg_server. Delete the /var/empty
directory.

I'm guessing you already tried re-running /usr/bin/ssh-host-config on
the new system?

Here are some things I did to get it working - delete the cyg_server
and sshd users from Windows' Local Users and Groups (in case it is
already there) - in your case since it's a new install, it might not
be there. Delete cyg_server from /etc/passwd in case it's there.
Possibly re-start (don't think this is required). Then re-run
ssh-host-config and try again.

HTH,
Balaji
