Not able to connect to FTP server

I have installed FileZilla server on my Server 2008 R2. I am trying to connect using WinSCP client but cant. Here is the log:

This does not look like Filezilla server at all. Are you sure you installed Filezilla server? Or maybe you are connecting to a wrong host or port.
