# Modifying settings for the "Provision and promote new domain controller" recovery option

Specify additional recovery option settings for the Provision and promote new domain controller option. This option automatically provisions the new servers from a clean image provided by Commvault or one that you provide.

This recovery method is available only when using the Recover AD forest to new domain controllers recovery type. It automatically provisions new servers from a clean image provided by Commvault or one that you provide and promotes them as domain controllers. Use this method after at least one domain controller in each AD domain has been restored from backup, to complete the AD infrastructure by promoting additional domain controllers from new servers.

Note

When you use the Provision and promote new domain controller option, and the software cache is hosted on a machine other than the recovery node, that machine must be accessible from the recovery network. For more information on ports and network requirements, see System requirements for Active Directory forest recovery.

## Go to the runbook

1. From the Command Center navigation pane, go to Protect > Active Directory.

   The Overview page appears.

2. Click the Forests tab, and then click the forest.

   The forest page appears.

3. Click the Runbooks tab, and then click the runbook.

   The runbook page appears.

## Start the Configure recovery options wizard

1. Click the Runbook settings tab.

2. In the Provision and promote new domain controller tile, select the domain controllers to configure.

3. Click Configure recovery options.

   The Configure recovery options dialog box appears.

4. For Target, select the host recovery target to create the recovered domain controllers on.

5. For Name prefix, enter a prefix to append to the display name of the recovered VMs.

6. Enable the Overwrite if VM already exists option when a VM with the specified name already exists.

   When you enable this option, the existing VM data and configuration are overwritten by the backup data and configuration of the client.

7. Click Next.

## Configure CommCell settings

1. For Associate with server groups, select the server groups to associate the recovered domain controllers with.

   The server groups are used to configure network communication between the recovered domain controllers and the rest of the Commvault infrastructure.

2. For Network gateway, enter the server name of the target gateway, and include the default port `8403`.

   Note

   The server name must match the Host Name value for the gateway under Manage > Infrastructure > Servers.

   For example: `networkgateway:8403`

3. Click Next.

## Configure machine settings

Important

- The Machine Configuration page does not apply to Microsoft Azure recovery targets.

- Select a network that is isolated from both the production Active Directory environment and the internet.

1. For Network, select the network switch associated with the isolated recovery network.

2. For Subnet mask, enter the subnet mask to apply to the recovered VMs.

3. For Default gateway, enter the IP address of the default gateway to apply to the recovered VMs.

4. For IP address, enter the IP address or the IP address range to apply to the recovered VMs.

5. Click Next.

## Configure credentials

Note

Use passwords that meet the password complexity rules for the Windows Server version that you are creating to prevent VM provisioning failures. For more information, see Password must meet complexity requirements.

1. For Administrative account, enter a credential.

   This credential is created on the recovered VM as an account with administrative privileges. Do not use a built-in account such as `administrator`.

2. For New DSRM password for the domain controller, enter a credential.

   This credential sets the directory services restore mode (DSRM) password on the domain controller. Only the password in the credential is used. The account name is ignored.

3. Click Save.
