I work for a large Oil Services company and support about 40,000 computers, soon to be 70,000. We are Global, and I have to support systems wherever the oil is. Most of these computers are connected in the Office, but a very large number of computers are not. They don't sit on our Domain, but rather, on a Rig in the middle of the Gulf, a Vessel in the middle of the ocean, or even in the back of a Truck. These are my Workgroup computers
