Installing an Additional Domain Controller by UsingIFM
When you install Active Directory Domain Services (AD DS) by using the install from media (IFM) method, you
can reduce the replication traffic that is initiated during the installation of an additional domain controller in an
Active Directory domain. Reducing the replication traffic reduces the time that is necessary to install the
additional domain controller.
Windows Server 2008 and Windows Server 2008 R2 include an improved version of the Ntdsutil tool that you
can use to create installation media for an additional domain controller. You can use Ntdsutil.exe to create
installation media for additional domain controllers that you are creating in a domain. The IFM methoduses the
data in the installation media to install AD DS, which eliminates the need to replicate every object from a partner
domain controller. However, objects that were modified, added, or deleted since the installation mediawas
created must be replicated. If the installation media was created recently, the amount of replication that is
required is considerably less than the amount of replication that is required for a regular AD DS installation.
