How do I allow FTP access to my windows 8.1 machine? It won't connect. Can't ping it either

This is a brand new HP Envy 4900MQ. I can connect with RealVNC. I can connect via Network and Homegroup (although I cannot write to most folders even though I have shared everything). This is why I need FTP. Here are the FTP error messages:

 

Opening Connection 10.0.1.50:21
FD_CONNECT - WSAECONNREFUSED: Connection refused
Cannot Connect to Site.


That is the correct address for this computer on my local network (which I have authorized in Norton).
