    Active Directory cannot exist without DNS so could you be more specific about your setup.

        Again, AD cannot exist without DNS so DNS has to be installed somewhere, if not on the DC. There's no requirement that the AD DNS be on a Windows Server or on a DC for that matter, the only requirement for the DNS server is that it support SRV records. You therefore have a couple of options:

        1. Leave DNS where it's at. You should be able to determine where it's at by looking at the DNS settings in the TCP/IP settings of the NIC properties on any client machine.

        2. Set up your DC as a secondary DNS server to the current DNS server.

        3. Migrate the current DNS zones to your DC.

          What IP addresses do you have as primary DNS for the clients and server(s)?
          Check these machines to see if there is a DNS Server service running.

          I guess you can actually uninstall DNS after AD has been setup but you may as well not bother in the first place.
