What is RODC and its uses?

RODC - Its A feature of Win2k8 

RODC - Read only Domain Controller.

Contains readable copy of Domain Controller which can be used at Location where there is no IT Pro or Security .

Read-only domain controllers (RODCs) are a new feature of Active Directory Domain Services (AD DS) in Windows Server 2008. RODCs are additional domain controllers for a domain that host complete, read-only copies of the partitions of the Active Directory database and a read-only copy of the SYSVOL folder contents. By selectively caching credentials, RODCs address some of the challenges that enterprises can encounter in branch offices and perimeter networks (also known as DMZs) that may lack the physical security that is commonly found in datacenters and hub sites. RODCs also offer a number of manageability improvements that are described in this guide. This section describes how RODCs work with the rest of the Active Directory environment, the main differences between RODCs and writable domain controllers, and the RODC features that can help resolve a number of security or manageability issues.

RODC stands for Read Only Domain Controller. It is a read only copy of domain controller.

Any changes that are made to AD objects are not processed by RODC but are forwarded to writable Domain controller.

RODCs are deployed where we do not have staff to maintain the infrastructure.

As it is a read only copy it can be deployed at site offices where there are security concerns.

Its a Read Only Domain Controller which act as a additional domain controllers but allows read action from the SYSVOL directory. Using this feature, we can allow or authenticate the third party tool to read the AD database.

 RODC help to authenticate users and computers and cache those credential to ease authentication .

RODC stands for Read Only Domain Controller. It is used for security purpose as it is not writable and it keeps the read only replica of domain controller

RODC's are a new feauture intriuduced from 2008 server . These additional domain controllers for a domain to host read-only database of AD and sysvol folders .

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

The RODC is useful when the company wants to have minimised domain login delay for the local users in that hosted network and not planning to have a local admin to manage them.

use case:

A remote mission site where military personals are deployed and the place is not much secure.

A departmental store which has a number of POS devices connected to AD then placing a RODC would be beneficial as it also minimises the local IT admin placement.

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.

RODC stands for Read Only Domain Controller. It is used for security purpose as it is not writable and it keeps the read only replica of domain controller.

RODC is a read only domain controller which can keep in less physical security area. RODC help to authenticate users and computers and cache those credential to ease authentication .
