Domain controller recovery settings and progress

For a diagram that illustrates the Forest Recovery Console elements, see Forest Recovery Console.

The Domain Controller Recovery Settings and Progress area has the General tab, the Progress tab, the Events tab, and a toolbar providing commands for managing the recovery of the domain controllers selected in the list.

In this section:

 

General tab

You can use this tab to specify recovery settings for one or more domain controllers selected in the list.

TIP

To specify recovery settings for multiple domain controllers at a time:

  1. Hold down CTRL, and then click to select domain controllers in the list of domain controllers.

  2. Use the General tab to specify recovery settings for the selected domain controllers.

The "Domain Controller Recovery Settings and Progress" area also provides the following commands for managing the recovery of domain controllers:

Recovery-related commands

  • Pause Next - Suspends the next operation performed during the current session on the selected domain controllers.

  • Resume - Resumes the suspended operation on the selected domain controllers. There are two choices which can be made. The first is Resume All DCs which allows the resume function of all Domain Controllers in the recovery and Resume Selected DCs which will only allow the resume for the selected Domain Controllers.

  • Retry All - Retries all operations for the selected domain controllers. Before retrying all operations, you may specify a different recovery method for the domain controllers.

  • Retry Last - Retries the last operation performed during the current session on the selected domain controllers.

  • Skip and Continue - Skips the error encountered for the selected domain controllers.

  • Abort - Cancels the recovery or verify settings operation for the domain controllers selected in the list.

Recovery Methods

Recovery method - Allows you to choose one of the following recovery methods for the domain controller selected in the list:

Restore Active Directory® from backup

Restores the domain controller from the backup you specify. For more information on backup selection methods, see Selecting backups for recovery. During recovery, Recovery Manager for Active Directory (RMAD) uses custom Internet Protocol security (IPSec) rules to isolate the domain controllers for which you selected this recovery method. For more information, see How does Recovery Manager for Active Directory isolate domain controllers during forest recovery?

The Directory Services Restore Mode (DSRM) can be paused during recovery by selecting the Pause recovery in DSRM to perform additional actions before booting to normal mode. on the Advanced Actions tab.

Restore SYSVOL

Restores contents of the SYSVOL share on the specified domain controllers. Read-only domain controllers (RODC) will be restored as well.

This method can be set only on the Recovery Mode tab of Recovery Project Settings. For details, see Recovering SYSVOL.

Install Active Directory®

Installs Active Directory® by using Microsoft’s tools.

For domain controllers running Windows Server® 2008 or earlier, this step uses the Dcpromo.exe tool.

For Windows Server® 2012-based domain controllers, this step uses the Windows PowerShell cmdlets Install- ADDSDomainController.

Installs Active Directory® by selecting the Install from Media (IFM) option. The selected servers will be promoted to Domain Controllers using a media file created from the Active Directory® backup.

Note: Make sure that a read-only domain controller (RODC) can be installed using a backup created from a read-only DC, or a writable DC can be installed using a backup created from a writable DC.

For details, see Install Active Directory recovery method.

Reinstall Active Directory®

Uninstalls Active Directory® and then installs it again by using Microsoft’s tools.

For domain controllers running Windows Server® 2008 or earlier, this step uses the Dcpromo.exe tool.

For Windows Server® 2012-based domain controllers, this step uses the Windows PowerShell cmdlets Install- ADDSDomainController and Uninstall-ADDSDomainController.

Uninstalls Active Directory and then installs it again by selecting the Install from Media (IFM) option.
The selected servers will be uninstalled and then promoted to Domain Controllers using a media file created from Active Directory backup.

After the Active Directory® reinstallation is complete, the domain controller replicates Active Directory® data from other domain controllers that were restored from backups in the recovery project.

Note

The Reinstall Active Directory® recovery method removes the global catalog by default if it is present on the domain controller being recovered. If you need to reconfigure the global catalog on the domain controller during Active Directory® reinstallation, select the Configure the domain controller as a global catalog server option in the Additional Settings section.

Uninstall Active Directory®

Performs a forced removal of Active Directory® from the domain controller and then demotes it to a member server in the domain. Domain controller’s metadata is completely removed from Active Directory®.

Note

When you use this method, the local Administrator password on the target domain controller is reset to the value you specify in the Set DSRM password and Confirm DSRM password text boxes in the Forest Recovery Console.

Adjust to Active Directory® changes

This recovery method is available and selected automatically when the domain controller is a Global Catalog server and belongs to the excluded domain, and either Rebuild GC, advertise normally or Rebuild GC, advertise fast is checked on the Global Catalog tab of the project settings. You can suppress any of the first two options using advanced settings.

How the Adjust to Active Directory changes method works:

  1. The agent removes lingering objects from other recovered domains, if any, using the Repadmin tool.

  2. If the previous step fails, the agent performs unhost and rehost of recovered domain partitions using the Repadmin tool.

  3. Only if both previous steps fails, the agent rebuilds Global Catalog on this domain without attempts to remove lingering objects. In case of full reset of Global Catalog, the replication of Global Catalog data may require additional time.

Do not recover

Isolates the domain controller from other domain controllers and completely removes it from the domain - no actions are performed on the domain controller itself. This option is used if the domain controller is inaccessible or you do not want to recover the domain controller due to any failures. RMAD removes all metadata of domain controllers that were not recovered from the Active Directory® forest.

Note

For recovery in the second phase only: If you are going to restore this domain controller on the second phase later, select the Keep this domain controller in the project option. For details, see Phased recovery.

Do nothing

This recovery method does not perform any actions on the domain controller and does not remove it. This method is available only if the Repromotion recovery mode is selected on the Recovery Mode tab of Recovery Project Settings. For details, see Phased recovery.

Options

Computer Access area

Allows you to specify the user name and password that will be used by RMAD to access domain controllers in the domain. This area has the following text boxes:

Target computer - Using this option you can specify the IP address for the target computer where Active Directory® will be installed. Only for the Install Active Directory® From Media, Install Active Directory®, and Restore to Clean OS methods.

What does Source DC mean? When performing a verification for one of the following recovery methods, Install Active Directory From Media, Install Active Directory, or Restore to Clean OS, if a target IP address is not supplied, then the currently selected DC’s address will be used, and the Source DC placeholder will be displayed in the Target computer text box. Using the source DC's address is only applicable during verification; when performing a restoration a valid target computer IP address must be supplied.

Use Default Domain Access Credentials - This option lets you use the default domain credentials to access domain controllers. To configure the default domain access credentials, select the option and press the view link that opens Recovery Project Settings. For more details, see Specifying recovery project settings. If the option is not selected, you can specify domain access credentials and DSRM password in the Domain Controller Access section. Otherwise, the Domain Controller Access section is not active.

User name and User password - Allows you to specify the user name and password with which RMAD will perform the following operations:

  • install, upgrade and check the Forest Recovery Agent

  • purge Kerberos tickets

  • manage FSMO roles

  • manage DNS client settings

  • manage Global Catalog servers

  • check forest health

These credentials are not used to access domain controllers during the project verification and forest recovery. Forest Recovery Agent uses RPC over SSL for communication. To get more details, see Managing Forest Recovery Agent.

CAUTION

The password for the specified account will be reset to the value specified in the project during the restore process. Make sure that the specified account existed in Active Directory® at the time of the creation of the selected backup - the backup can be selected by a user or by the specified backup criteria. Otherwise, the password will not be reset.

DSRM administrator - Allows you to specify the user name with which you want RMAD to access the selected domain controllers in Directory Services Restore Mode (DSRM).

Set DSRM password and Confirm DSRM password

Allows you to specify the DSRM password to be used by RMAD during the domain controller (DC) recovery.

When using these boxes, consider the current mode of the DC:

  • If the DC is already in DSRM mode. Use these boxes to specify the current password of the account you entered in the DSRM administrator text box. Otherwise, the DC recovery will fail.

  • If the DC is not in DSRM mode. Use these boxes to set a new temporary DSRM password for the account you entered in the DSRM administrator text box. RMAD will use this temporary DSRM password to restart the domain controller in DSRM during the recovery. Then, RMAD will replace this temporary password with the DSRM password stored in the backup you specified for the DC.

Target server network settings - Allows you to specify network settings applied to the recovered machine.

  • IP Address

  • Subnet mask

  • Default gateway

  • DNS Server

*Only for the Bare Metal Active Directory Recovery method

The network and DNS settings will be retrieved automatically from the BMR backup for the Bare Metal Active Directory Recovery method. If you need to edit the settings, click Change and specify the following options:

  • Retrieve network and DNS settings from a backup (used by default)

This option gets network settings for the selected domain controller from the backup

  • Use the following address

This option lets you specify network settings manually.

  • Select a DNS server automatically

If this option is selected, DNS server will be selected automatically.

  • Use the specified DNS server

This option lets you specify one DNS server or a list of DNS servers separated by semicolons.

NAT settings - This option lets you access recovered domain controllers that are located outside the network where RMAD is installed. *Only for the Bare Metal Active Directory Recovery method

Additional Settings area

This area has the following options:

  • Install the domain controller as a read-only - Use this option to install Read-Only Domain Controller(RODC) for Install Active Directory and Reinstall Active Directory recovery methods. This option will be selected by default if the original DC was read-only. Note that a read-only DC can be installed using a backup created only from the RODC. For more details, see Recovering read-only domain controllers (RODCs).

  • Configure the domain controller as a global catalog server - Use this option if you need to reconfigure the global catalog on the domain controller during Active Directory® reinstallation. This option will be selected by default if the original DC was a global catalog.

  • Preferred DNS server - Allows you specify a preferred DNS server for the domain controller during its recovery. For more information, see Assigning a preferred DNS server during recovery.

Elements in the Backup, Access Credentials and Install Active Directory parameters areas

Use backup criteria to automatically select a backup - Allows you to automatically select a backup file that meets particular criteria. To specify your criteria, click the Backup Criteria button on the toolbar.

Backup - Displays the path and name of the currently selected backup file from which the domain controller will be restored. To manually select a backup file, make sure the Use backup criteria to automatically select a backup check box is cleared, and then click the Select button.

Backup password - Allows you to type the password to open a password-protected backup.

Temporary backup folder - Here you can specify the folder on the domain controller to store temporary forest backup data.

Access Credentials - Allows you to enter the user name and password with which you want to access the location that holds the backup specified in the Backup file box. The account you specify must have Read access to that location. For BMR backups, the account you specify must have Read and Write access to that location.

Wipe all disks on the target machine before restore from the backup - If this option is selected, RMAD performs the DiskPart "clean all" command before recreating the disks. This command removes all partitions and cleans all disk sectors. The "Wipe all disks…" operation significantly increases the time of the restore process. *Only for the Bare Metal Active Directory Recovery method

Scan the selected backup (and Active Directory backup if applicable) for malware during the project verification - This option allows you to run antivirus checks for backups as a part of the settings verification process.

Restore from Active Directory Backup - This option allows you to restore the latest Active Directory/Registry data from the Active Directory® backup. *Only for the Bare Metal Active Directory Recovery method.

DIT database path - Specifies the location of the DIT database. *Only for the Install Active Directory From Media and Install Active Directory methods.

Log files path - Specifies the location of Log files. *Only for the Install Active Directory From Media and Install Active Directory methods.

SYSVOL path - Specifies the location of SYSVOL. *Only for the Install Active Directory From Media and Install Active Directory methods.
