Manage DNS Client Settings

You can use the Forest Recovery Console to view or change DNS client settings for each domain controller in your recovery project. In the DNS client settings, you can define the DNS servers used by the domain controller. You can manage DNS client settings before or after recovery of your project.

NOTE: Recovery Manager for Active Directory Forest Edition uses the domain controller access credentials to manage DNS client settings.

To view or change assigned DNS servers

  1. In the Forest Recovery Console, open the recovery project in which you want to view or change the assigned DNS servers.
  2. On the menu bar, select Tools | Manage | DNS Client Settings.
  3. In the dialog box that opens, use the following elements:

Table 32: Elements you can use

Element Description
Suggest Previous Settings Allows you to revert to the DNS client settings the domain controllers in your recovery project used before the recovery (that is, the settings stored in the recovery project).
Edit Allows you to change the DNS client settings for the domain controller selected in the list.
Undo Allows you to undo the changes you have made.
Apply Applies the changes you have made.

Configuring Windows Firewall

A firewall enabled in your environment may block traffic on ports used by Recovery Manager for Active Directory Forest Edition, preventing you from backing up or restoring data. Before you start using Recovery Manager for Active Directory Forest Edition, make sure your firewall does not block traffic on ports used by Recovery Manager for Active Directory Forest Edition. For more information about these ports, see the Deployment Guide supplied with this release of Recovery Manager for Active Directory Forest Edition.

This section provides instructions on how to configure the built-in Windows Firewall enabled on Windows Server 2008-based and Windows Server 2012-based domain controllers in a domain or forest you want to recover, so that Recovery Manager for Active Directory Forest Edition could recover that domain or forest. To ensure a successful recovery, create the following Windows Firewall security rules on all Windows Server 2008-based and Windows Server 2012-based domain controllers in the domain or forest (leave the default values for settings not mentioned below):

Rule 1 (inbound)

  • Rule type: Custom
  • Program path: %SystemRoot%\System32\Svchost.exe
  • Service settings: Windows Management Instrumentation (Winmgmt)
  • Protocol: TCP
  • Local ports: Any
  • Remote ports: Any
  • Local IP addresses: Any
  • Remote IP addresses: Any
  • Action: Allow the connection
  • Rule profile: Domain, private, and public
  • Allowed users: Any
  • Allowed computers: Any

Rule 2 (inbound)

  • Rule type: Custom
  • Program path: System
  • Service settings: Apply to all programs and services
  • Protocol: TCP
  • Local ports: 445
  • Remote ports: Any
  • Local IP addresses: Any
  • Remote IP addresses: Any
  • Action: Allow the connection
  • Rule profile: Domain, private, and public
  • Allowed users: Any
  • Allowed computers: Any

Rule 3 (inbound)

  • Rule type: Custom
  • Program path:
  • On a 32-bit system: <Product installation folder>\FRRestoreService.exe; on a 64-bit system: <Product installation folder>\FRRestoreService64.exe
    The default product installation folder is %ProgramFiles%\Quest\Recovery Manager for Active Directory Forest Edition.
  • Service settings: Apply to all programs and services

  • Local ports: RPC dynamic port range
  • Remote ports: Any
  • Local IP addresses: Any
  • Remote IP addresses: Any
  • Action: Allow the connection
  • Rule profile: Domain, private, and public
  • Allowed users: Any

Forest recovery overview

In general, a forest recovery is necessary if none of the domain controllers in the forest can function normally or if the corrupted domain controllers can spread dangerous data to other domain controllers. Some examples of forest-wide failures include:

  • None of the domain controllers can replicate with its replication partner.
  • Changes cannot be made to Active Directory at any domain controller.
  • New domain controllers cannot be installed in any domain.
  • All domain controllers have been logically corrupted or physically damaged to a point that business continuity is impossible (for instance, all business applications that depend on Active Directory are non-functional).
  • A rogue administrator has compromised the Active Directory environment.
  • An adversary intentionally or an administrator accidentally runs a script that spreads data corruption across the Active Directory forest.
  • An adversary intentionally or an administrator accidentally extends the Active Directory schema with malicious or conflicting changes.

Important: When you encounter the symptoms of a forest-wide failure, work with Microsoft Customer Support Service to determine the cause of the failure and evaluate any possible remedies. Because of the complexity and critical nature of the forest recovery process, the recovery of the entire Active Directory forest should be viewed as a last resort. Please consult Microsoft Customer Support Service before you take a definitive decision.

Developing a custom forest recovery plan

When planning for Active Directory forest recovery, you should first have a detailed topology map of your forest. The map should list all the information about the domain controllers, such as their names, FSMO roles, backup status, and the trust relationships between them.

IMPORTANT: Make sure that Forest Recovery Agents are installed and function properly on all domain controllers in the forest.

Because of the complexity and critical nature of the forest recovery process, it is strongly recommended that Active Directory administrator observe the following rules to prevent the forest failure:

  • Use only reliable and tested hardware, such as hard disks and uninterruptible power supply.
  • Test any new configuration in a test lab before deploying it in your environment.
  • Ensure that each domain in the forest has at least two domain controllers.
  • Keep detailed logs about the health state of Active Directory on a daily basis, so that in case of a forest-wide failure the approximate time of failure can be identified.
  • Regularly back up all domain controllers in the forest with Recovery Manager for Active Directory.
  • Use the Forest Recovery Console to create a recovery project for your forest. Verify the settings of your forest recovery project on a regular basis, especially when there are membership changes to the Enterprise Admins or Domain Admins group. This helps ensure that the IT staff fully understands the forest recovery plan.

Recovery Manager for Active Directory Forest Edition allows you to restore a domain in the forest to its state at the time of the last trusted backup. Consequently, the restore operation will result in the loss of at least the following Active Directory data:

  • All objects (such as users and computers) that were added after the last trusted backup.
  • All updates made to existing objects since the last trusted backup.
  • All changes made to either the configuration partition or the schema partition in Active Directory (such as schema changes).
  • Additionally, any software applications that were running on the domain controllers will need to be reinstalled on the domain controllers after the forest is recovered.
