Let us consider for a moment that the unthinkable has happened and your RODC is stolen. The evildoer mounts the AD DS database and attempts to retrieve passwords using a commonly available, umm, security research tool. However, instead of seeing more and more passwords appear as the password cracking progresses, the tool only shows empty or blank passwords for almost all accounts. In the past, if your DC was stolen, you would really have no choice but to reset all of the passwords in the domain a formidable task if you have thousands of users. However, in this case, you only need to deal with the specific accounts that have already been cached on that RODC. To be clear: With an RODC, you know exactly which passwords have been cached. You can check which ones have been replicated to the RODC by looking at the Password Replication Policy dialog box. Initially, only the computer itself and the special KRBTG account have passwords stored locally, as you can see in Figure 14-2. After clients begin to authenticate to the RODC, additional passwords may also be stored, as shown in Figure 14-3. You can also determine which users have attempted to authenticate to the RODC, but whose passwords have not been allowed to be cached. For example, notice in Figures 14-2 and 14-3

We have made it much easier to delete missing domain controllers, including RODCs, with a simple interface that can remove the departed RODC from the domain (no more metadata cleanup needed!) and also automatically reset the potentially compromised passwords. When you start to delete the computer object representing an RODC, you see the dialog pictured in Figure 14-6.

You should also read ahead to the section on BitLocker Drive Encryption. By using BitLocker on the Windows operating system volume of the RODC, you can prevent the thief from even being able to access the local copy of the AD DS database which, at a minimum, buys you time to reset passwords in an orderly fashion. Administrative Role Separation With Role Separation you can delegate the local administrator role of an RODC computer to any domain user without granting that user any rights to the domain itself or to other domain controllers. In Windows Server 2003, DCs didn t have a local administrator; if you could administer a DC, you could administer the whole domain. Administrative Role Separation can allow a local branch user to log on to an RODC and perform maintenance work on the server, such as upgrading a driver, without allowing that user to log on to any other domain controller or manage the domain. RODC Benefits RODCs provide a way to deploy domain controllers more securely in a branch office location because they are designed to be placed in locations that require rapid, reliable, and robust authentication services but that might also have a security limitation that limits or prevents deployment of a writable domain controller. With an RODC, organizations can mitigate risks with deploying a domain controller in locations where physical security cannot be guaranteed. The RODC feature is clearly designed for branch offices, but it is an integral part of AD DS as well. Please review 9 for information about installing an RODC, using the RODC filtered attribute set, and configuring read-only DNS.
