STEPS:

1. Demote old domain controller to member server, then reboot
2. Rename old domain controller (or remove from domain), then reboot
3. Remove any reminants of old DC from active directory (computer account from ADUC, server object from ADSS)
4. Remove any reminants from DNS referencing the old DC
5. Wait for all AD replication to happen, 60-90 minutes and verify with repadmin /showrepl

Finally rename the new domain controller

  1. NETDOM computername OLDDCNAME.DOMAIN.LOCAL /add:NEWDCNAME.DOMAIN.LOCAL
  2. IPconfig /registerdns
  3. Wait for AD replication, 1 hr (absolute MUST, verify this) verify with repadmin /showrepl
  4. NETDOM computername OLDDCNAME.DOMAIN.LOCAL /makeprimary:NEWDCNAME.DOMAIN.LOCAL
  5. Reboot
  6. NETDOM computername NEWDCNAME.DOMAIN.LOCAL /remove:OLDDCNAME.DOMAIN.LOCAL
