Installing the Microsoft Loopback Adapter Driver
When you do a fresh installation of Windows NT 4.0, Microsoft recommends that you install the Microsoft Loopback Adapter driver, and then verify that networking is operating normally before installing any NICs. The Loopback Adapter driver enables the computer to connect to local network resources that then allow alerter and messenger services to start on a

Performing a Fresh Installation of Windows NT on a
Backup Domain Controller
CAUTION: 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.
CAUTION: 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.
