Promoting Domain Controllers.

There are times you need to bring up a domain controller at a remote site.  Either to take over the from the current Dc on a temporary or permanent basis.

For a permanent basis, it is best if you can use a physical machines.  You can beat the replication traffic jam by backing up the current DC system state and ship the backup.   The backup when restored to a simple Windows folder can be used for DCPROMO /ADV.  This will  pick up the contents of the local file when promoting the local server as a Domain controller.  This form part of a baseline for the new DC, so that all the objects  do not need to be replicated.

The downside is that you need to secure that CD from being passed around.
