I have a trust relationship between a nt domain and a. Obviously you should try and use the tree and forest concept rather than manual trust relationships with pure Windows domains. This is discussed in the.
When you create trusts using the method, you must supply the same trust password for each domain. As a security best practice, all trust passwords should be strong passwords. If you choose to create both sides of the trust simultaneously, you run the New Trust Wizard once.
When you choose this option, a strong trust password is automatically generated for you. You must have the appropriate administrative credentials for the domains between which you are creating the trust. Trust direction The trust type and its assigned direction affect the trust path that is used for authentication. A trust path is a series of trust relationships that authentication requests must follow between domains.
To determine this, the security system computes the trust path between a domain controller in the trusting domain and a domain controller in the trusted domain.
In the following illustration, the trust path is indicated by an arrow that shows the direction of the trust. All domain trust relationships have only two domains in the relationship: One-way trust A one-way trust is a unidirectional authentication path that is created between two domains.
However, users in Domain B cannot access resources in Domain A. Some one-way trusts can be either a nontransitive trust or a transitive trust, depending on the type of trust that is created.

Two-way trust All domain trusts in a Windows Server or a Windows Server R2 forest are two-way, transitive trusts. When a new child domain is created, a two-way, transitive trust is automatically created between the new child domain and the parent domain.
This means that authentication requests can be passed between the two domains in both directions. Some two-way relationships can be either nontransitive or transitive, depending on the type of trust that is created. Transitivity determines whether a trust can be extended outside the two domains between which the trust was formed. You can use a transitive trust to extend trust relationships with other domains. You can use a nontransitive trust to deny trust relationships with other domains.
Transitive trust Each time that you create a new domain in a forest, a two-way, transitive trust relationship is automatically created between the new domain and its parent domain. If child domains are added to the new domain, the trust path flows upward through the domain hierarchy, extending the initial trust path that is created between the new domain and its parent domain.
Transitive trust relationships flow upward through a domain tree as it is formed, creating transitive trusts between all domains in the domain tree. Authentication requests follow these trust paths. Therefore, accounts from any domain in the forest can be authenticated at any other domain in the forest. With a single logon process, accounts with the proper permissions can access resources in any domain in the forest.Fix: Trust relationship between this workstation and primary domain `failed
In addition to the default transitive trusts that are established in a Windows Server or Windows Server R2 forest, by using the New Trust Wizard you can manually create the following transitive trusts: A transitive trust between a domain in the same domain tree or forest that shortens the trust path in a large and complex domain tree or forest.
A transitive trust between a forest root domain and a second forest root domain. A transitive trust between an Active Directory domain and a Kerberos V5 realm The following illustration shows a two-way, transitive trust relationship between the Domain A tree and the Domain 1 tree. All domains in the Domain A tree and all domains in the Domain 1 tree have transitive trust relationships by default.
As a result, users in the Domain A tree can access resources in domains in the Domain 1 tree, and users in the Domain 1 tree can access resources in the Domain A tree when the proper permissions are assigned at the resource. Nontransitive trust A nontransitive trust is restricted by the two domains in the trust relationship. It does not flow to any other domains in the forest. A nontransitive trust can be a two-way trust or a one-way trust.
Nontransitive trusts are one-way by default, although you can also create a two-way relationship by creating two one-way trusts. In summary, nontransitive domain trusts are the only form of trust relationship that is possible between the following: A Windows Server or a Windows Server R2 domain and a Windows NT domain A Windows Server or a Windows Server R2 domain in one forest and a domain in another forest when the forests are not joined by a forest trust You can use the New Trust Wizard to manually create the following nontransitive trusts: A nontransitive trust between an Active Directory domain and a Kerberos version 5 V5 realm.
When to create an external trust: You can create an external trust to form a one-way or two-way, nontransitive trust with domains that are outside your forest. External trusts are sometimes necessary when users need access to resources in a Windows NT 4. When you establish a trust between a domain in a particular forest and a domain outside that forest, security principals from the external domain can access resources in the internal domain.
Active Directory Domain Services AD DS creates a foreign security principal object in the internal domain to represent each security principal from the trusted external domain.
These foreign security principals can become members of domain local groups in the internal domain. Domain local groups can have members from domains outside the forest. Directory objects for foreign security principals are created by AD DS, and they should not be modified manually. You can view foreign security principal objects in the Active Directory Users and Computers snap-in by enabling advanced features.

Trust Relationship between NT domain and a windows na.. - Windows /NT
Authentication requests must first travel a trust path between domain trees. In a complex forest this can take time, which you can reduce with shortcut trusts. A trust path is the series of domain trust relationships that authentication requests must traverse between any two domains.
Shortcut trusts effectively shorten the path that authentication requests travel between domains that are located in two separate domain trees.

Shortcut trusts are necessary when many users in a domain regularly log on to other domains in a forest. Using the following illustration as an example, you can form a shortcut trust between domain B and domain D, between domain A and domain 1, and so on. Using one-way trusts A one-way, shortcut trust that is established between two domains in separate domain trees can reduce the time that is necessary to fulfill authentication requests—but in only one direction.
For example, when a one-way, shortcut trust is established between domain A and domain B, authentication requests that are made in domain A to domain B can use the new one-way trust path. However, authentication requests that are made in domain B to domain A must still travel the longer trust path. Using two-way trusts A two-way, shortcut trust that is established between two domains in separate domain trees reduces the time that is necessary to fulfill authentication requests that originate in either domain.
For example, when a two-way trust is established between domain A and domain B, authentication requests that are made from either domain to the other domain can use the new, two-way trust path.
When to create a realm trust: This trust relationship allows cross-platform interoperability with security services that are based on other versions of the Kerberos V5 protocol, for example, UNIX and MIT implementations.
Realm trusts can switch from nontransitive to transitive and back. Realm trusts can also be either one-way or two-way.

Creating a Forest trust between two different Forests: This means that global users in the trusted domain can be authenticated for accessing resources in the trusting domain.
Global users from the trusted domain can log on to any computer in either domain and can access resources in either domain if they have the appropriate permissions. If you want to establish a two-way trust between two domains, you must create two trusts, one in each direction.
Administrators can set up trust relationships between domains by using the Policies menu in User Manager for Domains. The administrator on the accounts domain should permit the trust first, and then the administrator on the resource domain should complete the trust.
Only global accounts global users and global groups can cross trusts. Windows NT trusts are nontransitive. In other words, if domain A trusts domain B and domain B trusts domain C, it is not true that domain A trusts domain C.
By using trusts, you can join Windows NT domains into a variety of domain models, including the complete trust model, the master domain model, and the multiple master domain model.
You can join domains to supportor more users for enterprise-level networks. In Windowstrusts are always two-way. If domain A trusts domain B, users in either domain can access resources in the other domain if they have the appropriate permissions.
