This is a message we get on all the computers in our network here if we switch them on in the wrong order.

Basically, the computer that is our main one and wired into the gateway seems to be the key in our case. if this is switched on and has sorted out it's IP address then other computers that we connect to it with wireless network then just sort themselves out. BUt if the main one has to be reset.restarted then we get this message. Normally it's sorted if we just power them all down and switch on in above order.
