My wording here wasn't the best.  Yes, running "net start sshd" from
your own shell is the same as what happens when Windows starts the
service itself.  I was suggesting that you could get more debug output
by running 'sshd' with debug flags turned on at the shell prompt but to
do so you need a shell owned by the user running the service (SYSTEM
in most cases).  That's why I was pointing to the recipe for how to make
one of these shells.  You could do this from your own shell too but it
will either fail to give you valid information, mess things up so
the service won't run anymore, or both.  But from what you mentioned
below, you don't need this anyway.

Great!  Happy to help.
