When you rebuilt the machine, did you give it the same name and IP address?
Surmizing from the info you provided, on the machine holding the Primary
zone that failed, you could have made the zone on the other machine a
Primary, then built up the new box, then created a secondary of the zone
providing the existing machine as the master, then switched roles. The
duplicate appears to be saying it found two Primary copies of the same zone,
which we know won't be acceptable.
