Just a beginer

Hi I have just installed VNC Server on my remote box and VNC Viewer on 
my local box.  When I try and connect the local box to take control of 
my remote server it tells me it has not connected.
Connection is via a local LAN and I can PING both ways OK.
Have I missed something ?
I assume the idea is I can control the remote server from my local box. 
Is this the correct way round ?
Help please for a beginner in this area of computing.
