Forum:Buildcraft conductive pipe failures

So it seems that on the multiplayer server I play on, Buildcraft's wood conductive pipes do not take energy from engines, and if they do, the power doesn't travel through them and the other conductive pipes to any machines. I have tried almost every possible legitimate combination of engine, machine, and piping and none have worked. Any help on why this may be? I know nothing about how multiplayer servers work either btw..
