What is the purpose of Read-Only Domain Controllers?
A Read-Only Domain Controller (RODC) is a new type of domain controller in Windows Server 2008. Its main purpose is to improve security in office branches. In this post, I summarize the functionality of RODC. Read-only feature: An intruder on the RODC can’t manipulate the Active Directory database.
What the difference between domain controller and read-only domain controller?
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.
In which two circumstances should you deploy a read-only domain controller?
Enterprises tend to deploy RODC under two conditions viz.,
- When there is not enough physical security to the datacenter.
- When there isn’t enough bandwidth for establishing network connections.

What is RODC and what are its advantages?
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.
Can we have a domain with read only access?
Hi, There is no read only domain admin group in AD. Domain Users have read only access to most of the AD objects like ad users, computers and GPOs…..
