We put a surge protector on both ends when we did this. Each one
grounded to the ground rod on it's respective building.
Before we did that we'd blow switch ports with every lightning storm.
After we did that no more blown ports. Maybe Bill's way works too, but
one SS or two SS is not that big a difference in cost.
Fiber with media converters would eliminate any question of how to
ground it. Get a 1000ft pull box of 12F drop cable and get it
terminated. If you have the equipment this isn't much harder than
copper Ethernet. If you don't have the equipment then you pay somebody
who does.

Ethernet has no ground reference. It's a differential signal. If
you're using shielded cable, only ground one end (or neither end), and
you'll be fine.

I've got a client that needs a network line installed from their
house to another building but they are on separate power meters. I
understand that running a cable between two different ground points
is not advisable. Is there a way around this? A wireless link isn't
an option at this point.
