Hello,<br />
I am working on the forest recovery plan and testing in the test lab forest recovery if we will upgrade schema from 2008 to 2012 R2. We have 2003 schema master server. I would like to verify the command that is needed after recovering system state. <br />
Is it - authoritative restore: restore database ???<br />
<br />
In 2008 there is an option to restore the cn=schema partition, but in 2003 is different.<br />
<br />
Please advise if restore database will do the job of recovering forest to 2003. Thank you<br />
<br />
After you restored system state backup using NTbackup in dsrm mode do below before rebooting,<br />
<br />
&nbsp; &nbsp;1. At a command prompt, type ntdsutil, and then press ENTER.<br />
&nbsp; &nbsp;2. Type authoritative restore, and then press ENTER.<br />
&nbsp; &nbsp;3. Type restore database, press ENTER, click OK, and then click Yes.<br />
&nbsp; &nbsp;4.Reboot

Authoritative restore using ntdsutil 2003 schema

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.

Active Directory

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
