Could you stop the service, as described on the page you mention, and 
then start it manually by doing the following:

sshd -D -dd


Once this is running, try to ssh to it from another cygwin window.
The instance of sshd should process one connection - failed or not.
Post the output from sshd so that we can get a better idea of what's 
happening.

As a thought though.. Running any firewalls on that machine? (They 
/shouldn't/ affect localhost connections, but I don't trust them...

of little lives, false security has lulled the madness of this world
into a slumber. Wake up! An eye is upon you, staring straight down and
keenly through, seeing all that you are and everything that you will
never be. Yes, an eye is upon you, an eye ready to blink. So face
forward, with arms wide open and mind reeling. Your future has
arrived... Are you ready to go?
