Forestdnszone

Transitioning from Windows 2003 to Windos2008, I ran into a problem. We use Infoblox DNS and when I went to Demote the final 2003 controller it says there are two replics, forestdnszone and Domaindnszone on the controller and ask if I want to delete them. I really want to know if its safe to delete these ?

Windows uses DNS zones in few ways:

- Primary zone (plain text file)
- Secondary zone (plain text file)
- Stub zone (plain text file)
- Active Directory Integrated zone (all date is stored on a domain partition)

When you set up DC based on 2003 and you choose DNS with AD-I (ActiveDirectory Integrated zone) it stores its local DNS database on a domain partition. So, if you are sure that you don't need anymore DC and its DNS zones you can simply removed them during demotion process.

But remember, if other domain or clients rely on that/those zone(s), they will loose access to resolve them correctly.
