hi all experts,


i m bit confused between the relation between the domain controller
(the hardware machine running the active directory ) and the domain
they are managing.

suppose i have one domain bar.com. and i have one subdomain
foo.bar.com. to run this subdomain foo.bar.com i have to dcpromo a
machine and create a new child. now can i add another machine as a
domain controller for foo.bar.com ?

when ever i dc promo a machine it becomes domain controller. isnt every
domain controller supposed to create a new domain or is it that we can
have multiple domain controllers serving the same domain?

thx.
ravinder.

Click to expand...
A domain can have and usually does have more than one domain controller.
There will be a root domain (eg bar.com), and for most people that is
all they need. The minimum recommended setup is to have a root domain
with *two* domain controllers, because if you have only one DC and it
dies, the domain dies with it, essentially.

When you dcpromo a machine to be a domain controller and there is an
existing domain, you are given the option to be part of the existing
domain or to create a new child domain.

Cheers,

Cliff
