Render Farm: Instruction to build up a RenderFarm?

I´m trying to use the render images on a second computer using the Render Farm. I bulit up the Render Farm due to a descriptopn from Mc Neel Wiki, but it doesntt work the way it should. Is there a step by step description to build up the farm and to use it? Also for the network and the network folder. I´m not familiar with buld up network-folders on Windows 7.
