Description

The Add-ADDSReadOnlyDomainControllerAccount cmdlet creates a read-only domain controller (RODC) account that can be used to install an RODC in Active Directory.

Examples

-------------------------- EXAMPLE 1 --------------------------

PS C:\> Add-ADDSReadOnlyDomainControllerAccount -DomainControllerAccountName RODC1 -DomainName corp.contoso.com -SiteName NorthAmerica

Description

---

Adds a new read-only domain controller (RODC) account to the corp.contoso.com domain using the North America site as the source site for the replication source domain controller.

Parameters

-AllowPasswordReplicationAccountName

Specifies the names of user accounts, group accounts, and computer accounts whose passwords can be replicated to this RODC. Use "None" if you want to keep the value empty. By default, only the Allowed RODC Password Replication Group is allowed, and it is originally created empty.

Type:	String[]
Position:	Named
Default value:	NULL
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Credential

Specifies the user name and password that corresponds to the account used to install the domain controller. Specify "(get-credential)" when using this parameter to prompt the user to supply a password.

-DenyPasswordReplicationAccountName

Specifies the names of user accounts, group accounts, and computer accounts whose passwords are not to be replicated to this RODC. Use "None" if you do not want to deny the replication of credentials of any users or computers. By default, Administrators, Server Operators, Backup Operators, Account Operators, and the Denied RODC Password Replication Group are denied. By default, the Denied RODC Password Replication Group includes Cert Publishers, Domain Admins, Enterprise Admins, Enterprise Domain Controllers, Enterprise Read-Only Domain Controllers, Group Policy Creator Owners, the krbtgt account, and Schema Admins.

Type:	String[]
Position:	Named
Default value:	NULL

Type:	String
Position:	Named
Default value:	<mandatory>
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-DomainName

Specifies the domain name for the user name (account credentials) for the operation. This parameter is required. It also helps to specify the forest where you plan to install the domain controller or create an RODC account.

Type:	String
Position:	Named
Default value:	<mandatory>
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-Force

Forces completion of the cmdlet even if issues are found in the process of creating the RODC account.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-InstallDns

Specifies whether the DNS Server service should be installed. If no value is provided, the default behavior is to automatically compute DNS configuration behavior based upon the existing environment.

Type:	SwitchParameter

-ReplicationSourceDC

Specifies the name of the domain controller to be used as the source for replicating to this RODC.

Type:	String

-SkipPreChecks

Specifies that only a base set of validations will be performed when this cmdlet is executed. This behavior is equivalent to the validations that were performed when using Dcpromo.exe in earlier versions of Windows Server to add a domain controller. When this switch parameter is set, it specifies that additional preliminary checks should be bypassed. For more information on the scope of these additional preliminary checks that the ADDSDeployment module performs by default when using Windows Server 2012, refer to the table in the section "Prerequisite Checking" in the Understand and Troubleshoot AD DS Simplified Administration in Windows Server 2012 guide located at http://go.microsoft.com/fwlink/?LinkID=237244.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Aliases:	wi
Position:	Named
Default value:	False

Notes

• Once you have added the RODC account, you can add an RODC to a server computer by using the Install-ADDSDomainController cmdlet with the -ReadOnlyReplica switch parameter.
• You can also delegate the ability to attach the server to a non-administrative group or user. If you are deploying RODCs in delegated administration scenarios where the machine accounts are pre-provisioned, creating the RODC account is the first stage of the RODC installation process and needs to be done by a member of the Domain Admins group. In these scenarios, once an administrator uses this cmdlet to add the RODC account in Active Directory Domain Services (AD DS), the second stage of the installation can occur. This involves attaching an actual server computer in a remote location (such as a branch office) that will operate as the RODC for the specified account created using this cmdlet.
