What does RODC mean?
A read-only domain controller (RODC) is a server that hosts an Active Directory database’s read-only partitions and responds to security authentication requests.
What is difference between DC and RODC?
RODC & writable DC differences: Active Directory Database – DCs host the only writable copies of the Active Directory database and therefore can perform read and write operations against the directory database. RODCs host read-only copies of the AD database which do not include security principal secrets (passwords).
What is RODC and Rwdc?
The main features of an RODC are as follows: A read-only AD Domain Services (AD DS) database–Applications that need only database read access can use the RODC; however, any database changes must be made to a read-writable DC (RWDC), then replicated back to the RODC.
What is RODC in Active Directory?
An RODC is a new type of domain controller that hosts read-only partitions of the Active Directory database. Except for account passwords, an RODC holds all the Active Directory objects and attributes that a writable domain controller holds. However, changes cannot be made to the database that is stored on the RODC.
Why RODC is required?
The main reason to introduce RODCs is to allow a Domain Controller to exist in a remote office that may have few users or less physical security as well network security requirements while not sacrificing performance for the remote location.
Why do we configure RODC?
The RODC Options page enables you to modify the settings: Delegated Administrator Account. Accounts that are allowed to replicate passwords to the RODC. Accounts that are denied from replicating passwords to the RODC.
Why do you setup a RODC?
It was created to be used in places where a domain controller is needed but the physical security of the domain controller could not be guaranteed. For example, it might be placed in a remote site that is not very secure and that has a slower WAN link.
Should I use RODC?
The main benefits of an RODC are as below: Reduced security risk to a writable copy of Active Directory. Better logon times compared to authenticating across a WAN link. Better access to the authentication resource on the network.
How does a RODC work?
To wrap it up, when a user account is not cached, the RODC forwards the authentication to a writable Domain Controller which does the authentication. If the Users password is allowed to be cached, then the RODC will pull that through a replication request.
How do you set up a RODC?
Click on the “Promote this server to a Domain Controller” link. In the Active Directory Domain Services Configuration Wizard, select Add a domain controller to an existing domain. In the next step, check the Read-only domain controller (RODC) box and provide a password for Directory Service Restore Mode (DSRM).
