We have 2 subnets. One for our main office and one for the colo. Our backup dc is at the colo and our PDC is at the main office. The IP schema for the main office was changed to an entirely new subnet. Now what I've does was on the PDC, I went into AD sites and Services and added the new subnet. Then I deleted the old one. I rebooted the backup domain controller and noticed that the IP changes within the forward lookup zone did copy over. But the reverse lookup zones did not. What would be the correct process to get the backup dc to copy those changes over?
