A child domain is a domain that shares
part of a domain name, more
specifically the right part of the domain name, with another domain. For
example, nkdsolutions.com is the \'parent\' domain while
virginia.nkdsolutions.com is the \'child\' domain. You have to have the
parent domain in order to have the child domain. Domains are not really the
security boundary that they were in WINNT 4.0 - in WIN2000 and WIN2003 it is
really the forest that is the security boundary. You would have to run
dcpromo on a member server and create the child domain.
A member server is simply a machine (
usually a server-class system ) that
runs either WIN2000 Server or WIN2003 Server and is joined to the domain
just like any workstation ( a machine running WIN2000 Pro or WIN XP Pro ).
It is not a Domain Controller ( but can become one if you run \'dcpromo\' on
it ). You would typically find that your File Server / Print Server is run
on a Member Server or that Exchange 2000 / Exchange 2003 is installed on a
Member Server or that Terminal Services / Citrix is installed on a Member
An additional Domain Controller is
simply that - an additional Domain
Controller to an existing domain. So, if nkdsolutions.com already has one
Domain Controller and you want to add a second ( due to the redundancy
issue....or maybe you have a lot of user account objects or whatever ) you
would simply run dcpromo on a system and stipulate that you want this to be
an additional Domain Controller to the nkdsolutions.com domain.
