I have OpenSSH running on WIndows 2003 SP2. When a user uploads a file, the file has no permissions for owner, group, or world. The folder is owned by Administrators:SSH-Users. The ssh daemon account is in the Administrators group, and the user is a member of the SSH-Users group. With my limited unix knowledge I would look to using 'umask' but it is not included in the installation package...
