UseExistingAccount Operation

Applies To: Windows Server 2008, Windows Server 2008 R2

The following options are available for the UseExistingAccount operation during an unattended installation of Active Directory Domain Services (AD DS). Options that are new in Windows Server 2008 appear in bold text.

Parameter	Possible values	Default value	Description
/ApplicationPartitionsToReplicate	"partition_DN_1 partition_DN_2 ...partition_DN_n"		Specifies application partitions to be replicated in the format of "partition1" "partition2". If * is specified, all application partitions will be replicated. Use space-separated (or comma-and-space-separated) distinguished names, with the entire string enclosed in quotation marks.
/CriticalReplicationOnly	Yes | No	No	Specifies whether the promotion operation performs only critical replication before reboot and then continues, skipping the noncritical (and potentially lengthy) portion of replication. The noncritical replication happens after the role installation finishes and the computer restarts.
/DatabasePath	path_to_database_files	%systemroot%\NTDS	Specifies the fully qualified, non–Universal Naming Convention (UNC) path to a directory on a fixed disk of the local computer that contains the domain database, for example, C:\Windows\NTDS.
/DNSOnNetwork	Yes | No	Yes	Specifies whether the DNS Server service is available on the network. This is used only when the network adapter for this computer is not configured with the name of a DNS server for name resolution. Specifying No indicates that DNS server will be installed on this computer for name resolution. Otherwise, the network adapter must be configured with a DNS server name first.
/LogPath	Path_to_log_files	%systemroot%\ NTDS	Specifies the fully qualified, non-UNC path to a directory on a fixed disk of the local computer that contains the domain log files, for example, C:\Windows\NTDS.
/Password	password		Specifies the password that corresponds to the user name (account credentials) that is used to promote the domain controller.
/RebootOnCompletion	Yes | No	Yes	Specifies whether to restart the computer upon completion, regardless of success.
/RebootOnSuccess	Yes | No	Yes	Specifies whether to restart the computer upon successful completion of an operation.
/ReplicaDomainDNSName	DNS_domain_name		Specifies the fully qualified domain name (FQDN) of the domain in which you want to promote an additional domain controller.
/ReplicationSourceDC	DNS_name_of_source		Indicates the FQDN of the partner domain controller from which Active Directory data is replicated to create the new domain controller.
/ReplicationSourcePath	path_to_installation_media		Indicates the location of the installation media that will be used to install a new domain controller.
/SafeModeAdminPassword	password | None		The password for the administrator account to use when you start the computer in Safe Mode or a variant of Safe Mode, such as Directory Service Restore Mode (DSRM). You cannot specify a blank password.
/SkipAutoConfigDNS	No value is required.		This switch is for expert users who want to skip automatic configuration of client settings, forwarders, and root hints. The switch is in effect only if the DNS Server service is already installed on the server. If you specify this switch, ensure that zones are created and properly configured before you install AD DS. Otherwise, this domain controller will not operate correctly. If the DNS Server service is not installed on this server, this switch is ignored.
/Syskey	NONE | system key		Specifies the system key for the media from which you replicate the data.
/SysVolPath	path_to_SYSVOL_folder	%systemroot%\ sysvol	Specifies the fully qualified, non-UNC path to a directory on a fixed disk of the local computer, for example, C:\\Windows\SYSVOL.
/UserDomain	domain_name		Specifies the domain name for the user name (account credentials) that is used for promoting a domain controller.
/UserName	Domain\user_name		Specifies the user name (account credentials) that is used for promoting a domain controller. We recommend that you specify the account credentials in the domain\user_name format.
