What type of replication does an RODC perform?

What type of replication does an RODC perform?

An RODC replicates updates to the domain from a writable domain controller using inbound-only replication. Password replication policy defines whether the credentials of the user or computer are cached on an RODC.

How do you check a RODC replication?

The first command that we are run is “Repadmin /replsummary” to check the current replication health between the domain controllers. The “/replsummary” operation quickly and concisely summarizes replication state and relative health of a forest.

What Is Denied RODC Password replication Group?

The Denied RODC Password Replication Group is a domain local group that specifies users and groups whose passwords cannot be cached on RODCs. By default, this group contains the following highly-privileged users and groups: The Enterprise Read-Only Domain Controllers group.

What is RODC and explain its purpose?

An RODC is a new domain controller (DC) mode in Windows Server 2008. It lets you store an Active Directory (AD) domain database read-only copy on the DC, but it has much more functionality than just a database read-only copy. If an RODC is compromised and the set modified, a Server 2008 RWDC won’t replicate the values.

How does a RODC work?

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.

Why do administrators have to use RODC?

This feature lets you easily separate server administrators from domain administrators, but only on an RODC. When you deploy an RODC on a branch office file server, you can grant the local staff administrative rights to manage that file server without extending those rights to other domain controllers (DCs).

How do you troubleshoot AD replication issues?

If AD DS cannot be removed normally while the server is connected to the network, use one of the following methods to resolve the problem:

1. Force AD DS removal in Directory Services Restore Mode (DSRM), clean up server metadata, and then reinstall AD DS.
2. Reinstall the operating system, and rebuild the domain controller.

Where is RODC used?

RODC, which was designed to be used in branch offices that cannot support their own domain controllers, can be used in a Windows Server 2008 environment or higher.

What is the difference between DC and RODC?

The difference is that a DC holds writable files containing sensitive data, such as passwords, about all users and computers throughout the domain. An RODC, on the other hand, stores read-only data about a subset of users and computers in the domain which it has been authorized to authenticate.

Who can administer RODC?

RODCs are meant to be administered by almost anyone since they are standard servers. However, there is risk with this. If regular users are delegated admin access to one or more RODCs, these RODCs either shouldn’t cache passwords or allow only the minimum number of accounts required to cache passwords.
