This topic covers the architecture of virtualized domain controller cloning and safe restore. It shows the processes cloning and safe restore with flowcharts and then provides a detailed explanation of Pdc Machines Linkedin Inc each step in the process. Virtualized domain controller cloning architecture. Virtualized domain controller safe restore architecture. Virtualized domain controller cloning relies on the hypervisor platform to expose an identifier called VM-Generation ID to detect creation of a virtual machine.
DIT during domain controller promotion. When the virtual machine boots up, the current value of the VM-Generation ID from the virtual machine is compared against the value in the database. If the two values are different, the domain controller resets the Invocation ID and discards the RID pool, thereby preventing USN re-use or the potential creation of duplicate security-principals.
The domain controller then looks for a DCCloneConfig. If it finds a DCCloneConfig. In a mixed environment where some hypervisors support VM-GenerationID and others do not, it is possible for a clone media to be accidentally deployed on a hypervisor that does not support VM-GenerationID.
Pdc machines linkedin ui presence of DCCloneConfig. Therefore, if a DCCloneConfig. The clone media can be subsequently moved to a hypervisor that pdc machines linkedin ui VM-GenerationID and then cloning can be retried.
However, cloning will not be initiated, so the secondary DC will continue to run under the same identity as the source DC. This secondary DC should be removed from the network at the earliest possible time to avoid any inconsistencies in the environment. The following diagram shows the architecture for an initial cloning operation and for a cloning retry operation.
These processes are explained in more detail later in this topic. An existing virtual machine domain controller boots up in a hypervisor that supports VM-Generation ID.
Even if it is null, the next computer creation will mean it still clones, as a new VM Generation-ID will not match. If the IDs match, this is not a new virtual machine and cloning will not proceed.
If a DCCloneConfig. The server continues booting normally. This is how every reboot of any virtual domain controller operates in Windows Server DIT from a previous domain controller or it is a restored snapshot. If not, it continues with snapshot restoration operations. See Virtualized domain controller safe restore architecture.
If there is no dccloneconfig. If it does not exist, this is a first attempt at cloning for this virtual machine. The guest implements the VDC object duplication safeguards of invalidating the local RID pool and setting a new replication invocation ID for the domain controller.
If it is already set to 0x1, this is a "retry" cloning attempt, where a previous cloning operation failed. The VDC object duplication safety measures are not taken as they had to have already run once before and would unnecessarily alter the guest multiple times.
If the file does not exist in any pdc machines linkedin ui location, the guest checks the IP address for duplication. If the IP address is not duplicated, the server boots up normally. If there is a duplicate IP address, the computer boots into DSRM to protect the network from pdc machines linkedin ui duplicate domain controller. If the file does exist in a valid location, the NTDS service validates its settings.
If the file is blank or any particular settings are blank then NTDS configures automatic values for those settings. If the DcCloneConfig.
The guest disables all DNS auto-registration to prevent accidental hijacking of the source computer name and IP addresses. The guest stops the Netlogon service to prevent any advertising or answering of network AD DS requests from clients. If there are services or programs installed that are not pdc machines linkedin ui the default exclusion allow list or the custom exclusion allow list, cloning fails and the guest boots into DSRM to protect the network from a duplicate domain controller.
If the guest's source computer object holds domain head extended permission of "'Allow a DC to create a clone of itself" then cloning proceeds.
If the guest's source computer object does not hold that extended permission, cloning fails and the guest boots into DSRM to protect the network from a duplicate domain controller. If this is pdc machines linkedin ui PDC cloning, then the guest renames the local computer and reboots. After reboot, it goes through step 1 - 10 again, then goes to step The guest provides the pdc machines linkedin ui settings to the DS Role Server service, which commences promotion.
The guest contacts the PDCE. All existing Kerberos tickets flush. The guest is renamed. The promotion process creates a new invocation ID and recreates the NTDS Settings object for the cloned domain controller irrespective of cloning, this is part of domain promotion when using an existing NTDS. DIT pdc machines linkedin ui. NTDS replicates in objects that are missing, newer, or have a higher version from a partner domain controller.
The NTDS. DIT already contains objects from the time the source domain controller went offline, and those are used as possible in order to minimize replication traffic inbound. The global catalog partitions are populated. The guest re-enables DNS client registration now that the computer is uniquely named and networked. The guest pdc machines linkedin ui the DCCloneConfig.
Windows does not use this value, but instead provides it as a marker for third parties. When an administrator restores the virtual machine from a previous snapshot, the current value of the VM-Generation ID from the virtual machine is compared against the value in the database. There are two scenarios where safe restore can occur:. When a virtual domain controller is started after a pdc machines linkedin ui has been restored while it was shut down.
If the virtualized domain controller in the snapshot is in a suspended state rather than shutdown, then you need to restart the AD DS service to trigger a new RID pool request. The following flowchart shows how safe restore occurs when a virtual domain controller is started after a snapshot has been restored while it was shut down.
When the virtual machine boots up after a snapshot restore, it will have new VM-Generation ID provided by the hypervisor host because of pdc machines linkedin ui snapshot restore. Because the two IDs do not match, it employs virtualization safeguards see step 3 in the previous section.
This part of the safe restore overlaps with the cloning process. Although this process is about safe restore of a virtual domain controller after it boots up following pdc machines linkedin ui snapshot restore, the same steps happen during the cloning process.
The following diagram shows how virtualization safeguards prevent pdc machines linkedin ui induced by USN rollback when a snapshot is restored on a pdc machines linkedin ui virtual domain controller. At time T1, the hypervisor administrator takes a snapshot of virtual DC1. This value is supplied by the hypervisor.
At a later time T2, users are added to this DC consider users as an example of updates that could have been performed on this DC between time T1 and T2; these updates could actually be a mix of user creations, group creations, password updates, attribute updates, and so on. In this example, each update consumes one unique USN though in practice a user creation may consume more than one USN.
They are same, as no rollback has happened yet, so the updates are committed and USN moves up toindicating that the next update can use USN Pdc machines linkedin ui updates replicate out to DC2 at the next replication cycle. At time T3, the snapshot taken at time T1 is applied to DC1. As a result, the updates performed on DC1 subsequent to the application of snapshot will safely converge.
In addition, the set of updates that were performed pdc machines linkedin ui DC1 at T2 which were lost on DC1 after the restore of the snapshot would replicate back into DC1 at the next scheduled replication because they had replicated out to DC2 as indicated by the dotted line back to DC1.
After the guest employs virtualization safeguards, NTDS replicates Active Directory object differences inbound non-authoritatively from a partner domain controller. The up-to-dateness vector of the destination directory service is updated accordingly.
Skip to main content. Contents Exit focus mode. Note This part of the safe restore overlaps with the cloning process. Note The preceding illustration is simplified to explain the concepts. Note If the hypervisor does not provide a VM-Generation ID for comparison, the hypervisor does not support virtualization safeguards and the guest will operate like a virtualized domain controller that runs Windows Server R2 or earlier.
