I have demoted a number of DC's recently and I see that DNS server role is still installed on all of them. Also I see in the reverse lookup zones that all the old Name server records are still there. My dns is integrated with AD.
1. Once I demote the old DC, can remove dns server role from that machine safely? I dont want zones disappearing or anything of that nature.
2. Do I have to manually delete all old name server records?
