We have a corporate office and 25 locations. We have three DNS, AD servers; 2000, 2003, and a 2008. At the remote sites we have about 50 devices. We have computers, network printers, wall mounted computers, wireless devices, laptops, time clocks, copiers, and scanners. We have been starting to get computers to drop off the domain. Do I need to place a DNS, AD server at each location, since we are getting so many devices, or do I need to get rid of my windows 2000 DNS, AD server. Does computers dropping of the domain have anything to do with too many devices at the remote facility or maybe the old DNS, AD server.?
