All: I have a related question that may be dated at this point but of which I'm curious. Some time ago we had a problem with a DNS server we located on a totally separate network to achieve DNS server diversity. At one point there was a failure on that network so that our DNS server loacted there could not be reached. It appeared from the reports/complaints we received that a number of client systems/resolvers had decided to only request data from the nonfunctional DNS server and despite failing on that wouldn't ask our other listed DNS servers. They therefore could not resolve addresses for otherwise functional network assets. I seem to remember this was somehow related to systems running Microsoft OS's. Am I confused or could it be that Microsoft knows something about this? Chuck Scott
