PasswordReplicationAllowed:{"security_principal" \| None}	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.

If no such site exists, the default is the site of the replication source domain controller.
SkipAutoConfigDns	Skips automatic configuration of DNS client settings, forwarders, and root hints. This parameter is in effect only if the DNS Server service is already installed.

Parameter:value	Description and default
AdministratorPassword:"administrator password"	Specifies a local administrator account password when AD DS is removed from a domain controller. The default is an empty password.

RemoveApplicationPartitions:{Yes \| <No>}	Specifies whether to remove application partitions during the removal of AD DS from a domain controller. The default is No.
RemoveDNSDelegation:{<Yes> \| No}	Specifies whether to remove DNS delegations that point to this DNS server from the parent DNS zone. The default is Yes.
RetainDCMetadata:{Yes \| <No>}	Retains domain controller metadata in the domain after AD DS removal to allow a delegated administrator to remove AD DS from an RODC. The default is No.
UserDomain:"domain_name"	Specifies the domain name for the user name (account credentials) for the operation. This parameter also helps to specify the forest where you plan to install the domain controller or create an RODC account. If no value is specified, the domain of the computer will be used.
UserName:"user_name"	Specifies the user name (account credentials) for the operation. If no value is specified, the credentials of the current user are used for the operation.

Examples

The following example supplies an answer file named NewForestInstallation:

dcpromo /answer:NewForestInstallation

The following example creates the first domain controller in a new child domain where you expect to install at least some Windows Server 2003 domain controllers:

dcpromo /unattend /InstallDns:yes /ParentDomainDNSName:contoso.com /replicaOrNewDomain:domain /newDomain:child /newDomainDnsName:east.contoso.com /childName:east /DomainNetbiosName:east /databasePath:"e:\ntds" /logPath:"e:\ntdslogs" /sysvolpath:"g:\sysvol" /safeModeAdminPassword:FH#3573.cK /forestLevel:2 /domainLevel:2 /rebootOnCompletion:yes

The following example creates an additional domain controller with the global catalog, and it installs and configures the DNS Server service:

dcpromo /unattend /InstallDns:yes /confirmGC:yes /replicaOrNewDomain:replica /databasePath:"e:\ntds" /logPath:"e:\ntdslogs" /sysvolpath:"g:\sysvol" /safeModeAdminPassword:M6$,U8Gvx4 /rebootOnCompletion:yes
