I am trying to setup the DNS Service on an Apple Mac Leopard Server 10.5 Advanced, using Server Admin. However the correct settings will not be saved properly. When I click on the Zones icon, I can see 2 records for the Primary Zone and the Reverse Zone. However when I expand these there is no Machine record or Reverse Mapping Record. If I try to ADD them, the IP address reverts to 10.0.0.1. If I change the IP addresses and create the correct records, they get 'lost' after I save the configuration. Has anyone any ideas about how to resolve this?
