I have a windows server 2008 r2 64bit system. I know that you can create a ftp site but what is the process of creating a sftp site?

here you go! http://technet.microsoft.com/en-us/library/cc771012(WS.10).aspx

That looks like just to configure ftp. I need to create and configure SFTP(SSH FTP).

Hello, Microsoft currently does not provide a solution for securing FTP traffic using FTP over SSH (SFTP). More information here: http://learn.iis.net/page.aspx/310/what-is-new-for-microsoft-and-ftp-75/ You can configure FTPS. For SFTP, you have to search for other third party tools.

You can add SFTP support to your existing IIS infrastructure, by using CompleteFTP Enterprise Edition, which has a 'gateway' feature. You can also use it as a standalone SFTP (and FTP/FTPS) server. You only need the much cheaper Standard Edition for that.
