You cannot reload a dynamic zone. Could that be the problem? A serial number higher than 2^32 will not load. Instead of adding 2^31 - 1, subtract 2^31 + 1. Or try adding 2^30 (or subtracting 3 * 2^30). Make sure to reload the zone after each change, or if your zone is dynamic, use a dynamic update that adds the SOA record again and sets the new serial number. Regards, Chris Buxton BlueCat Networks
