Administrator role separation: A user in the RODC can be granted with administrator privileges for carrying out maintainance operations such as server upgrade.
However, this administrator privilege will not have permission to make any changes in the DC. Hope it clarifies your confusion about RODC. In following few posts, we will practically see how we can setup a RODC and what all additional settings we need to configure.

Aaron 12 years ago. Hi Michael Pietroforte, Thanks for adivce Mate. I believe that dell has idrac9 or 10's out now. Dell just supports their product better with warranty history, drivers etc.
Hp just tells me that warranty has expired I don't get that Vivek 11 years ago. Vivek, that is normal. Vicky 9 years ago.

Microsoft and Meta formerly Facebook have announced a multi-faceted Workplace integration with Teams, allowing their joint customers to communicate and collaborate securely with each other.
As this is a new feature for Windows Server , the likelihood that you will be tested on RODC in the exam is highly likely, so taking a little extra time to learn its features and the role it plays in the new server infrastructure is worth doing. I always mention that the need to get hands-on experience with any product you are studying is key to learning it properly, and Read Only Domain Controllers are no exception.
You would need to build two servers or virtual machines within your domain, with one obviously being the RODC. The main reason for using an RODC is mainly for security purposes, while also providing domain resiliency at remote offices. If a remote office has poor physical security or is only serving a small number of very non-IT minded staff, there is no good reason to have a fully writable domain controller onsite. When you take a moment to consider what is held on a domain controller—namely all of your Company user accounts, including your infrastructure accounts—if these were to be compromised, it would be a massive security risk to your network.
Microsoft obviously realizes that this is a big issue for companies that often have small offices but also have domain requirements. Small networks often come with further downsides, such as poor WAN links.
The main fact to remember about a RODC is that they are just that: read only. It is important to note that the replication is one directional and that all information that is written to the RODC is from a writable domain controller and changes are only made during the replication cycle. As with any configuration-themed exam, you are expected to know how to manage a product end-to-end, including the installation.
With regards to installing an RODC you will be expected to know the preparation steps, the installation itself, and any further configuration required. If you have installed any domain-based role in the past, you will be aware of the active directory preparation commands you must run on the forest, domain, and the schema; additionally, prepping the group policy engine is also required. For your exam, you should make sure you understand the following commands and why they should be run prior to installation:.
As mentioned previously, you must have a writable domain controller for the RODC to replicate with, so you must specify this in the installation. From here you can setup the PRP password replication policy ; if you are following Microsoft best practice which you always would, of course! For your exam, you should also be aware that you can set up the installation of the RODC via an unattended installation or delegated installation where two different people can be responsible for the installation at different times.
As with any additional domain controller role, replication is the key to the successful transfer of information between servers. The replication of user information is there, of course, and is presented to users as and when they need them to supply a domain login. However, the passwords are cached on the server, and only once the RODC has contacted a writable domain controller of authentication.
This is where you should take note of a key term you will come across in your exam: the password replication policy PRP. This feature is what dictates what can be written to an RODC, therefore limiting the amount of sensitive information available to a remote office.
Also, by default, core roles such as the Domain admins are never allowed as part of the replication policy. Once you have enabled the accounts that will be cached on the RODC, the users at that remote site can logon to the domain as before. Any additions in terms of users, group membership, or group policy will apply on the next replication cycle.
You can prepopulate cached passwords on the RODC if you know that they are going to be required; for example, if you were running an application at the remote office that requires registering an SPN service principle name , then this feature will allow it to register correctly. You can disable password caching to further limit access to the RODC, which is worth bearing in mind for the exam if this is listed as a requirement.
There are a couple of things to keep in mind in regards to the importance of replication when using a RODC: firstly without contact with a writable domain controller the RODC, cannot update itself and will start to cause issues such as password changes, group policy updates, and authenticating new users to the domain from the remote office. Both of these points will be likely exam question areas, especially anything related to replication issues between sites that cause logon issues.
This is another nice security feature, as it keeps the DNS from being polluted at the remote office, which can then cause name resolution issues throughout the entire estate.
