if performed incorrectly, this procedure can destroy the primary domain controller security database. before you proceed, back up your system.

    a fresh installation of windows nt on a backup domain controller requires the following:

    ■ installation of the nic driver

    ■ network connectivity

    because the nic driver installation requires that the latest microsoft service pack first be installed, and because there is no way to install a service pack during a windows nt fresh installation on a backup domain controller, you must first set up two servers as primary domain controllers, and then demote one of them to a backup domain controller.

    do not use this procedure if sql or microsoft exchange are on the primary domain controller that you wish to demote to a backup domain controller. if these items are on the primary domain controller, you must reinstall them after you finish this procedure.

    if performed incorrectly, this procedure can destroy the primary domain controller security database. use the rdisk /s command to make emergency repair diskettes to backup the server security databases on the two servers before attempting this procedure.

    1 install windows nt 4.0 with service pack 6a on two servers set up as primary domain controllers. (follow the procedure in "installing the ms loopback driver in windows 4.0," above.)

    2 connect the two servers to the same network.

    3 create two domains in the same network. set up the server and domain names.

    for example:

    server/domain name

    server one server-1

    domain one domain-1

    server two server-2

    domain two domain-2

    4 place server-1 in domain-1.

    5 place server-2 in domain-2.

    6 set the same administrator password on both server-1 and server-2.

    7 setting up server 1

    8 start server manager on domain-1\server-1. from the start menu, select programs/ administrative tools (common)/server manager.

    9 from the computer menu, select add to domain.

    10 select windows nt backup domain controller as the computer type.

    11 in the computer name field, enter the domain and server name. for example: domain-2\server-2

    12 click add.

    13 click close.
