Uninstalling Forest Recovery Agent

To uninstall the Forest Recovery Agent, you can use one the following methods:

  • Uninstall the Forest Recovery Agent from the Forest Recovery Console.

  • Access the target computer directly to uninstall the Forest Recovery Agent.

The latter method allows you to remove the Forest Recovery Agent from a domain controller that was demoted to member server and thus excluded from your recovery project.

To uninstall the agent from the Forest Recovery Console

  1. Open the recovery project where you want to remove the Forest Recovery Agent.

  2. Use the List of Domain Controllers area to select the domain controllers from which you want to remove the agent.

To select multiple domain controllers, hold down CTRL, and click the domain controllers you want to select.

  1. On the menu bar, select Tools | Manage | Forest Recovery Agent or DCs.

  2. In the dialog box that opens, click the Uninstall Agent button.

To uninstall the agent by accessing the computer directly

  1. Log on to the computer from which you want to uninstall the Forest Recovery Agent.

  2. In Control Panel, click Uninstall a program.

  3. In the list, select Quest Forest Recovery Agent, and then click Uninstall.

 

Rebooting domain controllers manually

You can use the Forest Recovery Console to selectively reboot domain controllers in the current recovery project. You can reboot domain controllers either in normal mode or Directory Services Restore Mode (DSRM).

To reboot domain controllers

  1. In the List of Domain Controllers area, select the domain controllers you want to reboot.

    To select multiple domain controllers, hold down CTRL, and click the domain controllers you want to select.

  2. On the menu bar, select Tools | Manage | Forest Recovery Agent or DCs.

  3. In the dialog box that opens, click the Reboot button, and then click one of the following:

  • Reboot in Normal Mode. Reboots the domain controllers in normal mode.

  • Reboot in DSRM. Reboots the domain controllers in Directory Services Restore Mode.

 

Resetting DSRM Administrator Password

You can use the Forest Recovery Console to selectively reset the Directory Services Restore Mode (DSRM) administrator password on domain controllers in the current recovery project. You can reset the DSRM administrator password to the value specified in the domain controllers’ recovery settings or specify a new DSRM administrator password.

To reset DSRM administrator password

  1. Use the List of Domain Controllers area to select the domain controllers on which you want to reset the DSRM administrator password.

    To select multiple domain controllers, hold down CTRL, and click the domain controllers you want to select.

  2. On the menu bar, select Tools | Manage | Forest Recovery Agent or DCs.

  3. In the dialog box that opens, click More, and then click Reset DSRM Password.

  4. Use one of the following options:

    • Reset password to the value in recovery settings. Allows you to reset the DSRM administrator password to the value specified in the recovery settings for each domain controller. For more information about recovery settings, see Domain controller recovery settings and progress.

    • Reset password to this value. Allows you to reset the DSRM administrator password to the value you type in this option.

  5. When you are finished, click Apply.

 

Purging Kerberos Tickets

During the forest recovery process, the Key Distribution Center Service Account (KRBTGT) password is automatically reset to different values on all domain controllers. As a result, after the restore, incorrect Kerberos tickets may be cached on domain controllers and other servers in the domain. This can lead to authentication errors for various services after the forest recovery operation within renew ticket lifetime (10 hours by default).

In order to avoid authentication errors, make sure that the KRBTGT account has been successfully replicated and then reset Kerberos tickets.

NOTE

Recovery Manager for Active Directory uses the domain controller access credentials to purge Kerberos tickets. For more details, refer Table 24 in the General tab section.

To purge Kerberos tickets

  1. After the restore process is completed, in Forest Recovery Console, click the Purge Kerberos Tickets option in the Post-Recovery Actions window or select Tools | Manage | Purge Kerberos Tickets.

  2. In the Purge Kerberos Tickets window, click Apply to start replicating the KRBTGT account in the domains and then purge the tickets on the domain controllers.

  3. Click OK to close the window.

    • For read-only domain controllers, the option purges Kerberos tickets and does not perform the replication of KRBTGT account.

    • The purge Kerberos tickets operation does not affect domain controllers that were excluded from the forest.

  4. Then, all users have to re-logon to get a new Ticket Granting Ticket (TGT).
