We had something like this pop up a couple of years ago, although DNS was not yet involved. We were simply making a VPN connection. Our 10.1.1.x network had only about 130 nodes; the other 10.1.1.x had about 500 nodes. Guess who the poor #@&% was who had to come in at 11 PM and spend 10 hours changing one network to a 10.1.2.x network... -------------------------------------- Richard McClary, Systems Administrator ASPCA Knowledge Management 1717 S Philo Rd, Ste 36, Urbana, IL 61802 217-337-9761 http://www.aspca.org
