<shudder>  Glad to see you searched the web though.

Ugh. Spaces in the path.  That's just asking for trouble.
I recommend that you at least mount C:\Documents and Settings
(and Stuff. Oh My!) to /home and make sure /etc/passwd is using
the /home path.

And did you try the same on Cygwin?

And that makes me wonder what Windows platform you're
running on and how you're running the service, which
leads me to worry that maybe you've spent too much time
at erdelynet.com.  So now is a good time to read and
follow the problem reporting guidelines outline here:

<http://cygwin.com/problems.html>

We need information about your configuration, including
details of how you set up sshd, if you're still having problems.

Well, if you have no respect for the .ssh directory, then
that's fine.  I wouldn't wander into any ssh neighborhoods
alone for a while though. ;-)
