    Install Windows on the new machine

    Assign the new computer an IP address and subnet mask on the existing network
    Make sure that the preferred DNS server on new machine points to the existing DNS Server on the Domain (normally the existing domain controller)

    Join the new machine to the existing domain as a member server

    From the command line promote the new machine to a domain controller with the DCPROMO command from the command lineSelect Additional Domain Controller in an existing Domain

    Once Active Directory is installed then to make the new machine a global catalog server, go to Administrative Tools, Active Directory Sites and Services, Expand ,Sites, Default first site and Servers. Right click on the new server and select properties and tick the Global Catalog checkbox. (Global catalog is essential for logon as it needs to be queried to establish Universal Group Membership)

    Make sure DNS in installed on the new server. Assuming that you were using Active Directory Integrated DNS on the first Domain Controller, DNS will have replicated to the new domain controller along with Active Directory.

    Both Domain Controllers by this point will have Active Directory, Global Catalog, DNS.

    If this DC is going to be in addition one you have you can leave it at that, if its a replacement then you need to move the FSMO roles to the new machine see

    Change the preferred DNS server on the clients to point to the new machine.
    You can then demote the old DC and remove it from the domain

    I forgot to say at the begining that the best way to create a copu of AD is to create an additonal domain controller.
