Recovery Manager for AD Disaster Recovery Edition 10.0.1 - User Guide

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:

Specifying fallback IP addresses to access a domain controller

By default, Forest Recovery Console uses DNS names to access domain controllers in the forest recovery project. If the DNS name of the domain controller is not resolved, the console uses the IP addresses that are saved in the project file. The project file accumulates all previously resolved DNS addresses or addresses that were manually entered by a user for each domain controller.

To specify the list of fallback IP addresses for a domain controller

1. On the menu bar, select Tools | Manage | Forest Recovery Agent or DCs.
2. Select a domain controller whose address list you want to change. The IP addresses column shows the list of IP addresses that are stored in the project file.
3. To edit the list, click the IP address or select More | Edit IP Adresses... in the Manage Domain Controllers dialog.
4. In the dialog box that opens, you can specify fallback IP addresses for the domain controller in order of their priority. These addresses will be saved in the project file and can be used during forest recovery when the DNS server is unavailable.

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:

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.

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.
