In Windows 2000, promoting a member server to become an additional domain controller free 70-270 test questions in an existing domain, required replicating the entire directory database to the new domain controller. In case of low network bandwidth or a large directory database, this replication could take hours or even days to complete. Servers running Windows Server 2003 can be promoted using a restored backup taken from a Windows Server 2003 domain controller. This backup can be stored on any backup media (Tape, CD, or DVD) or a network share. You can find more information about backing up Active Directory in Chapter 3, "Administering Active Directory."
Using backup media to create an additional domain controller in your domain reduces the amount of replication required to copy the directory database across your LAN or WAN and will create an additional domain controller faster. This is because Active Directory only needs to replicate the changes that occurred after that backup was taken. The amount of replication that transpires depends on the age of the backup. The backup cannot ...
... be older than the tombstone lifetime of the domain, which is set to a default value of 60 days. Therefore, it is always recommended to use the most recent backup available.
If the domain controller that was backed up contained an application directory partition, it will not be restored on the new domain controller. For information about cre?ating an application directory partition on a new 70-270 practice test domain controller, refer to Chapter 5, "Configuring Sites and Managing Replication."
Although network bandwidth requirements will be greatly reduced by using this mechanism, network connectivity is still necessary so that
All critical objects are replicated to the new domain controller
Non-critical objects created after the backup was taken and other changes can be replicated to the new domain controller
Data stored in the Sysvol folder is replicated to the new domain controller
To copy domain information to the server from backup files, you must first back up the system state of a domain controller belonging to the domain in which this server will become an additional domain controller. Second, the system state backup must be restored locally on the server you are promoting. To do this using Windows Server 2003 backup, choose the option Restore Files To: Alternate Location.
If the domain controller you restored the system state from was also a global catalog, the Active Directory Installation Wizard will ask if you would like this domain controller free exam papers to become a global catalog as well.
