You can create an additional domain controller in a domain by installing Active Directory Domain Services (AD DS) on a server computer. When you are placing the additional domain controller in a remote site, you can install AD DS on the server either before or after you ship it to the remote site, as follows:
- 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 method uses the data in the installation media to install AD DS, which eliminates the need to replicate every object from a partner domain controller.
- Objects that were modified, added, or deleted since the installation media was 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.
The following tools are required to perform the procedures for this task:
Ntdsutil
activate instance ntds
ifm
create sysvol full <Drive>:\<InstallationMediaFolder>
You can save the installation media to a network shared folder or to removable media. The IFM process creates a temp database in the %TMP% folder. You need at least 110% of the size of the AD DS or AD LDS database free on the drive where the %TMP% folder is in order for the operation to succeed. You can redirect the %TMP% folder to another disk on the server in order to use more space.
robocopy.exe /E /COPYALL <source location> <destination location>
Example:
robocopy.exe /E /COPYALL c:\InstallationMediaFolder \\RODC01\IFM
