Apr 16, A two-way trust relationship between domains is simply the trust, Domain A does not trust Domain C. In a transitive trust relationship, In addition, Windows Server provides for another trust relationship called a.

This group has the rights to create one-way, incoming forest trusts to the forest root domain. If you hold this level of membership in both forests, you can set up both sides of an interforest trust at the same time. You must ensure that DNS is properly configured so that the forests can recognize each other.

In the case of a forest trust, both forests must be operating at the Windows Server forest functional level. Windows Server provides the New Trust Wizard to simplify the creation of all types of trust relationships.

The following sections show you how to create these trust relationships. Know the variations of the procedures so that you can answer questions about the troubleshooting of problems related to interforest access as they relate to the options available when creating trusts.

Domain-Wide Authentication This option authenticates users from the trusted domain for all resources in the local domain. Microsoft recommends this option only for trusts within the same organization.

Selective Authentication This option does not create any default authentication. You must grant access to each server that users need to access.

She will need to enter the trust password you specified in this procedure. Realizing that the research necessary to complete this project successfully required a high level of security, management asked the senior network administrator to set up a separate forest in the organization's Windows Server Active Directory design.

For the project to succeed, researchers needed access to certain data stored in the organization's existing forest. Their user accounts would be in the new forest. Users in the existing forest did not need to access data in the research forest. The administrator had to choose a trust model that would enable the appropriate levels of access.

With these needs in mind, the administrator decided to implement a one-way external trust relationship in which the existing forest trusted the research forest. It was then possible to place the researchers who needed access into a group that could be granted access to the appropriate resources in the existing forest. Because the trust relationship was one-way, no access in the opposite direction was possible.

We take a further look at the use of groups to grant crossforest access in Chapter 6, "Implementing User, Computer, and Group Strategies. Validate trust relationships This option enables you to verify that a trust has been properly created and that the forests can communicate with each other.

Change the authentication scope This option enables you to change the selection of domainwide authentication or selective authentication that you made during creation of the trust, should you need to modify access control to the trusting forest's resources.

Configure name suffix routing This option provides a mechanism that you can use to specify how authentication requests are routed across Windows Server forests.

It is available only when forest trusts are used. Validating Trust Relationships To access the trust's Properties dialog box and validate a trust relationship, follow Step by Step 3.

On the Trusts tab of the domain's Properties dialog box, select the name of the other domain or forest and click Properties. This action displays the trust's Properties dialog box, as shown in Figure 3. To validate the trust relationship, click Validate.

For example, the DNS forest name quepublishing. Consequently, name suffixes in one forest do not exist in another forest. Name suffix routing is a mechanism that can manage the routing of authentication requests across Windows Server forests that are connected by forest trust relationships. An external trust is always nontransitive and it can be a one-way or two-way trust. Realm trusts are always created between the Active Directory forest and a non-Windows Kerberos directory such as eDirectory, Unix Directory, etc.

The trust can be transitive and nontransitive and the trust direction can be one-way or two-way. If you are running different directories in your production environment and need to allow users to access resources in the either of the directories, you will need to establish a realm trust. You will be required to create a forest trust if you need to allow resources to be shared between Active Directory forests. Forest trusts are always transitive and the direction can be one-way or two-way.

You may want to create a shortcut trust between domains of the same Active Directory forest if you need to improve the user login experience.

The shortcut trust is always transitive and direction can be one-way or two-way. Important points about Active Directory trusts When creating Active Directory trusts, please take a note of the following points: You need to have sufficient permissions to perform trust creation operation. At a minimum, you will be required to be part of domain admins or enterprise admins security group or you must have been granted necessary permissions to create trusts.

As part of the trust creation operation, you will be required to verify the trust between two destinations. Verification can be done by using Active Directory Domains and Trusts snap-in or Netdom command line tool.

When creating external or forest trusts, you can select Scope of the Authentication for users. Selective authentication allows you to restrict access to only those identities in a trusted Active Directory forest who have been given permissions to resource computers in trusting Active Directory forest.
