Can not log in to recently enabled/configured sshd service

I have had similar thing happen to me before. Please try stop and
start the CYGWIN sshd service in Windows, try again. If that works,
then we might be having the same problem.

I forgot what I did exactly. Looking at my current setup, it seems
that the "TCP/IP Protocol Driver" is added in sshd's dependency list.
