Add a POWER FLAG to the GND net. Power to devices can come in several ways, i.e. you could have a regulator on board, and that will have a power out pin. Power out pins are automatically driven so DRC knows all about them.
Sometimes you will feed power into a board from an external source i.e. a wall wart type power unit, so all you have on the circuit is a couple of pins to attach wires to (or a socket) in these cases you need to tell the DRC system that there will be power available on these nets. Once DRC knows this it can check all the other devices for correct power in connections and such like. This is where the power flags come into use. Ground connections are a little bit odd, in that they serve several purposes, however when they are part of the power system, as they usually are, then the DRC sees them much the same as a power out port, and as such the GND needs to be driven just like VCC and so on. You will find that for most circuits you will need to add a power flag to the GND net.
