dns_domain_name string |  | When `state` is `domain_controller`, the DNS name of the domain for which the targeted Windows host should be a DC.
domain_admin_password string / required |  | Password for the specified `domain_admin_user`.
domain_admin_user string / required |  | Username of a domain admin for the target domain (necessary to promote or demote a domain controller).
local_admin_password string |  | Password to be assigned to the local `Administrator` user (required when `state` is `member_server`).

## Examples

    - name: Ensure a server is a domain controller
      win_domain_controller:
        dns_domain_name: ansible.vagrant
        domain_admin_user: testguy@ansible.vagrant
        domain_admin_password: password123!
        safe_mode_password: password123!
        state: domain_controller
        log_path: C:\ansible_win_domain_controller.txt

    # ensure a server is not a domain controller
    # note that without an action wrapper, in the case where a DC is demoted,
    # the task will fail with a 401 Unauthorized, because the domain credential
    # becomes invalid to fetch the final output over WinRM. This requires win_async
    # with credential switching (or other clever credential-switching
    # mechanism to get the output and trigger the required reboot)
    - win_domain_controller:
        domain_admin_user: testguy@ansible.vagrant
        domain_admin_password: password123!
        local_admin_password: password123!
        state: member_server
        log_path: C:\ansible_win_domain_controller.txt

    - name: Promote server as a read only domain controller
      win_domain_controller:
        dns_domain_name: ansible.vagrant
        domain_admin_user: testguy@ansible.vagrant
        domain_admin_password: password123!
        safe_mode_password: password123!
        state: domain_controller
        read_only: yes
        site_name: London
