What does RODC mean?
read-only domain controller
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.
Can you authenticate to a RODC?
If the password is cached, the RODC will authenticate the user account locally. If the user’s password is not cached, then the RODC forwards the authentication request to a writable Windows Server 2008 Domain Controller which in turn authenticates the account and passes the authenticated request back to the RODC.
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.
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 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.
How do I identify my RODC server?
In ‘Active Directory Users And Computers’ browse to the RODC’s computer object the DC Type should contain say ReadOnly if it is a RODC. The computer object properties on tab ‘Managed by’ should also show what type of DC it is.
Why do we need RODC?
What is RODC and what are its advantages?
Separation of administrator capabilities–An RODC can designate users as server administrators without granting any domain or other DC permissions. 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.
What are the benefits of using an RODC in a branch office?
Here are the benefits of deploying RODC:
- 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.
- Better performance of directory-enabled applications.
How do you set up a RODC?
Install a Read-Only Domain Controller (RODC)
- Open Server Manager.
- On the left pane, click AD DS.
- When the All Servers Task Details window opens, click Promote this server to a domain controller.
- On the Deployment Configuration page, with the Add a domain controller to an existing domain already selected, click Next.
How do I join a RODC server?
How to join a domain with a read-only domain controller (RODC)
- In the console tree, expand Sites, and then expand the site of the domain controller that you want to receive configuration updates.
- Expand the Servers container to display the list of servers that are currently configured for that site.
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.
