I built a Windows Server 2012 R2 PDC for a new domain. It's still in its infancy with only one DC and one member computer. Now I need to remove all traces of that domain and start fresh because:
- It needs to be renamed
- We're having trouble with an interforest AD migration (SID history won't migrate) and the AD admin at the source domain, who's been at this job a lot longer than me, says all he can think of is to start over with the new domain.
How far do I need to go with the existing DC? Can I just use Server Manager to remove the AD Directory Services and DNS roles, then rebuild them, or do I need to wipe and rebuild the server? I'm afraid of Windows hiding settings in the registry and not getting rid of them, like it does all the time elsewhere.
