Recovery Manager for AD Forest Edition 10.3 - User Guide

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.

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).

Managing the Global Catalog servers

You can use Recovery Manager for Active Directory (RMAD) to manage the global catalog servers in your Active Directory® forest before or after the recovery. For example, you can view which domain controllers currently hold the global catalog server role and manually remove or assign the global catalog server role to the domain controllers you want.

To manage the global catalog servers

1. In the Forest Recovery Console, open the recovery project in which you want to manage the global catalog servers.

2. On the menu bar, select Tools | Manage | Global Catalog Servers.

3. Do one of the following:

   • To assign the global catalog server role to a domain controller, select the check box in the Global Catalog Server column next to that domain controller.

   • To remove the global catalog server role from a domain controller, clear the check box in the Global Catalog Server column next to that domain controller.

   • To sort or group the domain controllers in the list by the criteria you want, right-click anywhere in the list, and then select an appropriate command from the shortcut menu.

4. When you are finished, click the Apply button for your changes to take effect.

Managing FSMO roles

You can use the Forest Recovery Console to view the current Flexible Single Master Operations (FSMO) role owners in your recovered Active Directory forest and manually change the FSMO role owners if necessary.

During the recovery, Recovery Manager for Active Directory uses an internal algorithm to automatically assign FSMO roles to the recovered domain controllers. After the recovery completes, you can view the current FSMO role owners and selectively reassign the FSMO roles if necessary.

To view and assign FSMO role owners

1. In the Forest Recovery Console, open the recovery project in which you want to view the current FSMO roles.

2. On the menu bar, select Tools | Manage | FSMO Roles.

3. Use the dialog box that opens to view the current FSMO role owners and reassign FSMO roles as necessary.

   You can use the following elements:

   Elements you can use

   Element	Description
   Suggest Previous Owners	Allows you to automatically distribute FSMO roles to the domain controllers (owners) that held these roles before the recovery (that is, the owners stored in the recovery project). After you click this button, use the Assign Role To column to view or specify new role owners. If a FSMO role owner no longer exists, the most optimal existing owner will be selected for that role.
   Suggest Optimal Owners	Click this button to automatically distribute FSMO roles to the most optimal existing owners in the recovered Active Directory forest.
   Clear	Click this button to undo the changes you have made in the Assign Role To column. You can only use this button before you apply the changes you have made.
   FSMO Roles	Lists all FSMO roles in the recovered Active Directory forest.
   Current Owners	Lists the current owner of each FSMO role in the recovered Active Directory forest.
   Assign Role To	Use this column to manually select a new owner for the corresponding FSMO role. You can also use this column to view the automatically selected new owners after you click the Suggest Prerecovery Owners or Suggest Optimal Owners button.

4. When you are finished, click Apply.

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.

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:
