Additional Active Directory Server Roles - MCTS Guide to Microsoft Windows Server 2008 Active Directory Configuration - page 488

AD LDS is first installed as a server role, and then one or more instances of AD LDS are
created. Before AD LDS can be removed as a server role, all instances must be removed in
Control Panel. Each AD LDS instance has its own data store and communication ports and a
unique service name, so to an application using AD LDS, each instance appears as a unique
copy of the service. When you create an AD LDS instance, you're prompted to choose one of
these two installation options:
• A unique instance —Uses the default configuration and schema partitions and can't repli-
cate with existing instances. Select this option when AD LDS is installed for the first time
or when you're creating an instance for a new directory-enabled application.
• A replica of an existing instance —Uses the configuration and schema partitions replicated
from an existing instance of AD LDS. Use this option when you're installing AD LDS and
it's already been installed on another server, perhaps for fault tolerance or load sharing.
In this activity, when you're instructed to log on as Administrator, make
sure you log on as the domain administrator rather than the local admin-
istrator account. This instruction applies to all activities that require log-
ging on as Administrator, unless noted otherwise.
