xna - move sprite from different pc using c# tcp/ip socket

Question

I don't have any experience with TCP/IP socket.net technology and XNA game. I have been learning both of them last few days. I found few TCP/IP Socket technology tutorial which only sending/receiving data such as Chat application. But I need to develop client server application using socket technology where I need control movement of sprite from client application(Different computer) using Mouse or Keyboard. This is not my field but my assignment requirements so no other option.  any help would be appreciated.
