Hello,
To share different resources between two different AD Domain, i think
to do
a trust relationship,
What is not known here is if these two different AD domains are within
the same Active Directory forest. If so, the trust is created
automatically.
By default, all domain trusts within a single Active Directory forest
are two-way, transitive trusts. There are three types of transitive
trusts that are used within a single Windows 2000 Server or Windows
Server 2003 forest. The first is the tree-root trust, which is created
by default when you create a new domain tree by using the Active
Directory Installation Wizard. The two-way transitive nature of
intra-forest trusts such as the tree-root trust allows all domains in
one tree to trust all domains in any other tree within the same forest.
The second type of trust is a parent-child trust. It is created
automatically when you create a new domain in an existing domain tree
by using the Active Directory Installation Wizard. When a new child
domain is created, a parent-child trust is established between the new
domain and the domain that immediately precedes it in the namespace
hierarchy.
The last type of trust that can be used between trees is a shortcut
trust, and is used to speed up access times to resources in a domain
that is deep within the tree hierarchy of another domain.
