How to Install RODC On Windows Server 2008 R2 Core

How to Install Read Only Domain Controller (RODC) on Windows Server

Hello Friends,

Today i am going to show to install Read Only Domain Controller on Windows Server 2008

The Windows Server 2008 Server Core installation does support Read Only Domain Controllers (RODC). This support makes Server Core ideal for brance office scenarios. To make a Server Core part of your domain as RODC, you use the unattended answer file with the following text with your settings and passwords

[DCInstall]
InstallDNS=Yes
ConfirmGC=Yes
RebootOnCompletion=Yes
ReplicaDomainDNSName=2008.lab
ReplicaOrNewDomain=readonlyreplica
ReplicationSourceDC=dc3.2008.lab
SafeModeAdminPassword=
SiteName=Default-First-Site-name
UserDomain=2008.lab
UserName=admin08
Password=
CreateDNSDelegation=No

You can place the text file on the root of your C drive on the server core and run the following command

dcpromo /unattend:unattend.txt where unattend.txt is the text file you created above

Later on we will discuss other embedded command line structures and built-in programs such as OCSETUP which will allow you to add roles and features to your server core. Keep in mind that making the domain controller is the only setup you must not use OCSETUP for, and you must utilize DCPROMO for it, otherwise your server may not function properly.

After running the above process, you will notice that from a Windows Server 2008 full installation, using ADUC we can readily confirm that our DC is RODC.
