3.2. Promoting a Domain Controller from Media
Tip
This recipe requires that the server being promoted run Windows Server 2003.
Problem
You want to promote a new domain controller using a backup from another domain controller as the initial source of the directory contents (DIT) instead of replicating the entire DIT over the network.
Solution
You first need to back up the system state of an existing domain controller in the domain the new server will go in. This can be accomplished by running the MS Backup utility found at Start → Programs → Accessories → System Tools → Backup.
Once you have a good backup, you then need to restore it to the new server, which can also be done using MS Backup. You should restore the files to an alternate location, not to their original location.
Next, run
dcpromo
with the/adv

After the

Enter a Restore Mode password and click Next.
Click Next to start the promotion.
