Three domains, named A, B,
and C
Domains A and B have a one-way trust relationship
in which domain A trusts B. The trust intersection of
these two domains is B. You can configure published
applications for all user accounts on domain B. Note
that a server that is a member of a Windows NT
workgroup can never belong to a multiple server
farm because there is no trust intersection between a
workgroup and a domain.
Domains A and B have a two-way trust relationship
in which domain A trusts B and domain B trusts A.
The trust intersection of these two domains is A and
B. You can configure published applications for all
user accounts on domains A and B.
Domains A and B have a one-way trust relationship
in which domain A trusts B. A server from a third
domain, named C, is added to the farm. C has a one-
way trust relationship with B, in which C trusts B.
The trust intersection of these three domains is B.
You can configure published applications for all user
accounts on domain B.
Domains A, B, and C participate in a master domain
model network in which domain A is the master
domain and B and C are subordinate domains.
According to the master domain model, domains B
and C each have a one-way trust with domain A in
which domain B trusts A and domain C trusts A. The
trust intersection of these three domains is A. You
can configure published applications for all user
accounts on domain A. This scenario works with
multiple master domains as well.
