Repeat the step to add But there is no harm creating a forward lookup zone in both sides as both forests are going to trust each other once trust is activated. To do this, log on to DomainA. To do this, log on to DomainB.
To do this Log on to DC1. Repeat the Steps in DomainB. To do this log on to DC1. Create External Trust Example: Creating incoming trust in DC1.
Open Active Directory Domains and Trusts. In the console tree, right-click the domain for which you want to establish a trust, and then click Properties. On the Trusts tab, click New Trust, and then click Next. On the Trust Type page, click External trust, and then click Next. On the Direction of Trust page, click One-way: On the Sides of Trust page, click This domain only, and then click Next.
On the Trust Password page, type the trust password twice, and then click Next. With the administrator of the other domain, agree on a secure channel password to be used in establishing the trust. On the Trust Selections Complete page, review the results, and then click Next. On the Trust Creation Complete page, review the results, and then click Next. On the Confirm Incoming Trust page, do one of the following If you do not want to confirm this trust, click No, do not confirm the incoming trust If you want to confirm this trust, click Yes, confirm the incoming trust, and then supply the appropriate administrative credentials from the specified domain.
Review these settings to ensure that you have made the correct selections. If any settings are incorrect, click Back and correct them. The Trust Creation Complete page informs you that the trust relationship was successfully created.
Click Next to finish the process. The Confirm Outgoing Trust page asks whether you want to confirm the outgoing trust see Figure 3. If you have configured the trust from the other side, click Yes, Confirm the Outgoing Trust.
The Confirm Incoming Trust page asks whether you want to confirm the incoming trust. Choices are the same as on the previous page. If you want to confirm this trust, enter a username and password for an administrator account in the other domain. The Completing the New Trust Wizard page verifies the confirmation of the trust from the other side.
You are returned to the Trusts tab of the domain's Properties dialog box see Figure 3. The name of the domain with which you configured the trust now appears in one or both of the fields according to the trust type you created. Click OK to close this dialog box. Creating a Forest Trust Recall that this type of trust can be created only between two Active Directory forests that are both operating at the Windows Server forest functional level.
Follow Step by Step 3. Type the name of the forest root domain with which you want to create a trust and then click Next. On the Direction of Trust page, select the appropriate direction for the trust and then click Next.
On the Sides of Trust page, specify whether you want to create the trust for this domain only or for both this domain and the specified domain, and then click Next. If you are creating the trust for both forests, specify a username and password for the specified forest and then click Next. If you are creating the trust for this forest only, specify a trust password, which the administrator in the other forest will need to specify to complete the creation of the trust for her forest.
Make a choice and then click Next. The Trust Selections Complete page displays a list of the options that you have configured refer to Figure 3. The Confirm Outgoing Trust page asks whether you want to confirm the outgoing trust refer to Figure 3.
If you want to confirm this trust, enter a username and password for an administrator account in the other forest. You are returned to the Trusts tab of the domain's Properties dialog box refer to Figure 3. Creating a Shortcut Trust Recall that this type of trust can be created between child domains in the same forest to expedite crossdomain authentication or resource access.
On the Direction of Trust page refer to Figure 3. If you are creating the trust for both domains, specify a username and password for an administrator account in the specified domain.
If you are creating the trust for this domain only, specify a trust password, which the administrator in the other domain will need to specify to complete the creation of the trust for her domain.
The Trust Selections Complete page displays a summary of the settings you have entered refer to Figure 3. Click Back if you need to make any changes to these settings. Then click Next to create the trust. Click Next to configure the trust. The Confirm Outgoing Trust page asks whether you want to confirm the other side of the trust. If you have created both sides of the trust, click Yes. Otherwise, click No and then click Next. The Completing the New Trust Wizard page informs you that you have created the trust.
Click Finish to return to the Trusts tab of the domain's Properties dialog box refer to Figure 3.

If you have created only one side of the trust, an administrator in the other domain needs to repeat this procedure to create the trust from her end.
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.
- How to create an external trust between two seperate domains/forests
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.
If the trust is in place and active, you receive a confirmation message box, as shown in Figure 3. Otherwise, you receive an error message, such as the one in Figure 3.
Configuring Name Suffix Routing When you initially create a forest trust, all unique name suffixes are routed by default. 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.
It enables name suffixes that do not exist in one forest to be used to route authentication requests to another forest. This includes child name suffixes. As a result, when you view name suffixes in the Name Suffix Routing tab of the domain's Properties dialog box, as shown in Figure 3.
If you add new child domains to either forest, they automatically inherit the name suffix routing properties of other domains in the forest. After you add a new name suffix and validate the trust, it appears on the Name Suffixes tab with a status shown on the Routing column of Disabled. The Status column indicates New for a newly created name suffix.
You may need to disable name suffix routing to prevent certain authentication requests from flowing across the forest trust. You may also need to enable name suffix routing for additional name suffixes you have created or to exclude a child name suffix from routing. The routing status in the Routing column changes.
In the case of enabling a new name suffix routing, the New entry disappears from the Status column. To exclude a child name suffix from routing, select the parent suffix and click Edit to display the Edit domain name dialog box see Figure 3. To exclude the name suffix, click Add.
The excluded name suffix appears on the Edit domain name dialog box. In such situations, the Status column on the Name Suffix Routing tab lists the conflict in the indicated domain.
You cannot enable this suffix for name routing until you have removed the conflicting name suffix for the indicated domain. Removing a Crossforest Trust Relationship Sometimes you might need to remove a trust relationship between two forests. For example, a contract may have completed or been terminated, an acquisition of one company by another may have fallen through, and so on.
You may need to remove and re-create a trust relationship if you have incorrectly specified properties such as an incorrect trust type or direction. On the Trusts tab of the domain's Properties dialog box, select the trust to be removed and click Remove.
Domain Trust Relationship between Two Domains - TechRepublic
You are asked whether you want to remove the trust from the local domain only or from the local domain and the other domain see Figure 3. If you want to remove the trust from both domains, select Yes, Remove the Trust from Both the Local Domain and the Other Domain, type the username and password for an account with administrative privileges in the other domain, and then click OK.
Click Yes on the next dialog box to confirm removing the trust. You are returned to the Trust tab of the domain's Properties dialog box. Notice that the name of the other domain has been removed. Understanding Trust Relationships Following are points to remember regarding trust relationships: In a one-way trust relationship, the trusting domain makes its resources available to users in the trusted domain.
A two-way trust relationship consists of two one-way trusts in opposite directions. By default in Active Directory, all domains in a forest trust each other with two-way transitive trust relationships.
You can also create shortcut trusts between child domains to facilitate rapid authentication and resource access. You need to explicitly set up all trust relationships between different forests. A one-way incoming trust allows users in your trusted domain to be authenticated in the other trusting domain, whereas a one-way outgoing trust allows users in the other trusted domain to be authenticated in your trusting domain. Two authentication scopes are available: Domainwide authentication allows users from the trusted domain to access all resources in the local domain.
