I have a remote Windows 2008 machine and the task at hand is to share out parts of its filesystem via SFTP for a single user.

Were commercial software an option things would be easy but I want freeware.

After trying out several different candidates such as Core FTP Mini SFTP Server, SilverShield and freeFTPd none them really qualified - either connection issues, zero configurability or bugs.

Is there a free and stable SFTP server for Windows 2008 which works out of the box?

Another option would be to install OpenSSH using Cygwin. The attached instructions are for Windows XP/Vista but I don't see why they wouldn't work on Windows Server 2008.

Cygwin is a kind of middle layer that allows *nix software to be compiled and run on Windows without modification. It is extremely handy and brings a lot of other *nix goodness to Windows. Oh, yeah and Cygwin is open source and free.

Cygwin gives only source compatibility, not binary compatibility - I made an edit suggestion to your answer. – peterh Aug 27 '14 at 9:01

After spending a few hours on the World Wide Web, turns out the answer is yes.

Meet KpyM Telnet/SSH Server which is a free, open source telnet/ssh server for Windows.

Installation is a breeze and it runs as a service.

The only caveat is the requirement to grant explicit access rights to SFTP home folder - KpyM authentication relies on Windows user accounts.

Why not use the freeSSHd ? We have been using this for our server and it does the job for us. It is free and easy to setup.

The download page is here

After you install it, check in your taskbar, the application should be running and the icon is hidden in the taskbar next to the clock.

It is worth noting that this server has a GUI for configuring the settings whereas the KpyM server only provides a command line interface (as far as I could tell). – Brian Hinchey Oct 22 '14 at 4:07

This is a free SFTP server which runs on Windows 2008 and is free for private use, or trial:

You can try out Server! as well. It's free for non commercial use, and your single user scenario fits the free license technical limitations.

And unlike Cygwin/OpenSSH solutions this one is Windows-native, as per your request.
