[ssh-l] OpenSSH/Cygwin failed password

I have installed cygwin on an NT4 machine and am having problems making an
SSH connection from a remote workstation. Here is the debug output when
running /usr/sbin/sshd:

$ ./sshd -d -d -d

Failed password for administrator from 192.168.30.151 port 2046

I am trying to login with the administrator account and I am *absolutely*
certain that I have the right password. :) Could something else be
interfering? I seem to be able to ssh to localhost successfully on the
cygwin host but it doesn't ask for a password so I'm assuming it is working
alright. There seems to be no "w" command so I don't know how to tell if
I've established a new shell environment.

Thanks in advance,

Chris.
