This Active Directory domain controller is a DNS server. If you remove Active Directory Domain Services (AD DS) from this computer, all of the DNS data that is stored in Active Directory-integrated zones will be lost. After you remove AD DS from this server, this DNS server will not be able to perform name resolution for the DNS zones that were Active Directory-integrated. Therefore, we recommend that you update the DNS configuration of all computers that currently refer to the IP address of this DNS server for name resolution with the IP address of a new DNS server. 

Do you want to continue removing AD DS from this computer?
