Non-transitive means that if domain A trusts domain B, and domain C trusts domain B, there is no trust relationship between domain A and C. One-way means that one domain is trusted—it has accounts to which the other domain wants to give access.
If domain A trusts domain C, then domain C is said to be trusted and domain A to be trusting. Domain A can grant file access to users and groups in the C domain.
Auditing Windows Active Directory Trust Relationships
Because the trust is one-way, a second trust—domain C trusting domain A—has to be created so that domain C can give domain resource access to users and groups from domain A. These features, one-way and non-transitive, meant, for many organizations, hundreds of trust relationships had to be created and managed. Windows In a Windows forest, no domain is an island. All domains are universally connected via Kerberos-style transitive trusts. But what if you need to grant access to your domain resources to users in an NT domain or those in another forest?
The trust relationship between this workstation and the primary domain failed.
These trust relationships are NT-style trusts; non-transitive, one-way, no Kerberos. If users from multiple domains in forest A require access to resources in forest B, multiple external trusts must be made. If multiple trusts are required, we begin to have the same problem as with NT trusts. Lots of management, lots of pain, diagrams blackened with arrows which represent the relationships.

A Better Trust Model Windows solves both of these problems: The need to create complete, Kerberos-style, transitive trusts between two forests, and the ability to limit what trust means, both in the forest trust, and in the external trust. The forest trust is, simply, just that. If I want to assign resource access in every domain in forest A to any user with an account in any domain in forest B, I can do so. In addition to a trust wizard there is new nomenclature. An incoming trust from A to B means that users and groups in B can be assigned access to resources in A.

A and B can represent domains joined in an external trust or forests in a forest trust. An outgoing trust, one from A to B, means that users and groups in A can be assigned access to resources in B.
Figure 1 illustrates an incoming trust from forest B to forest A. Note that users John and Mary, who have accounts in domains in forest B, are given access to folders on servers in two different domains in forest A. An incoming trust into forest A means users in forest B can be granted access to forest A resources. This will allow users in either domain or location to log on to either domain, depending on where their user account is stored.
So, if Ralph is visiting the TechSales office, logging on to a computer that is associated to the TechSales domain, he can still authenticate back to the BrainCore domain, since there is a trust.

What Trust Types Exist There are a few types of trusts that you might see when you audit or when you are establishing trusts in Active Directory. These are independent of one another and are established without combining options.
Internal trust - These are trusts established between Active Directory domains that are in the same Active Directory forest.
These trusts can be between parent-child domains or between parent top level domains, domains starting new trees in the forest. External trust to Windows domain - These are trusts that go outside of the Active Directory forest. These realms are what Unix use instead of Active Directory.
In essence, they are the same type of trust as compared to an external trust to a Windows domain. Cross-link trust - These trusts are internal to the Active Directory forest.
The concept is that a cross-link trust bypasses the traversal up the Active Directory tree, then down the Active Directory tree for domains that are multiple internal trusts away.
These trusts are created for efficiency of authentication within the forest when users are accessing resources in a domain that is not near where the user is located. Forest trust - These trusts were introduced with Windows Server domains. They provide a top level trust between two Active Directory forests. The goal is that all domains in both forests will be trusted, instead of having to create a trust between every domain to every other domain in the other forest. How to Audit Trusts In order to audit the trust relationships, you will need to either get a screen capture or ask for a command line output.
There are, of course, other methods, but these might require a purchase of software or to write a script. Not that these options are all that bad, but if there is a way to obtain the information without any cost, I typically try to lead the auditor down that path. The first option, screen capture, will come from the domain administrator. This screen capture will be of the Trusts tab for each domain that you need to audit.
So, if the network administrator has informed you that the company has three domains total, you will need a screen capture from each domain, totaling three screen captures. To obtain the screen capture, the domain administrator will need to use the Active Directory Domains and Trusts administrative tool.
This tool is on every domain controller and is one of the tools that is installed with the adminpak. To get to the correct screen, the administrator needs to expand the list of domains on the left pane, then right-click on each domain name.
When the menu appears, select the Properties option.
This will launch the Properties window for the domain. Here, select the Trusts tab to see the list of trusted and trusting domains, as shown in Figure 1. Active Directory Domains and Trusts allows you to see all domain trusts.The trust relationship between this workstation and the primary domain failed
If any trusts are established, they will appear in this list. If you choose to do the command line option, you will be using the nltest command.
