Creating a Active Directory Trust between two domains
All the trusts between domains in an Active Directory forest are different Active Directory forests if you need to allow users from one domain to. A trust is a relationship established between two different domains that There are different type of trust in Microsoft Active Directory domain such as and Windows Server domain using same principle written below. Our expert provides the steps to set up an Active Directory (AD) domain trust when Do you have instructions on creating a trust between two Active Directory (AD) domains' (Windows and I made the assumption that the DNS servers are the Domain Controllers. Can you trust AD's trust relationships? . Header 1.
New to Windows Serveryou can also be a member of the Incoming Forest Trust Builders group on the forest root domain. 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.
You might have to configure conditional forwarding to enable DNS servers in one forest to forward queries to DNS servers in the other forest so that resources are properly located.
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.

Also remember that a forest trust is the simplest way to connect forests when access to resources in multiple domains is required, and when Kerberos authentication across the forest boundary is needed.
Exam Alert If You Rename a Domain, Cross-Forest Trusts Are Invalidated If a question informs you that a domain has been renamed and users are unable to access resources in an external forest, the reason for this problem is that both external and forest trust relationships are invalidated by the rename process. You need to delete and re-create the trust relationships following the renaming process.

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.
The restrict access scenario is achieved by using the Selective Authentication feature, which is applicable only for external and forest trusts. How to create a trust You can use Active Directory Domains and Trusts snap-in or Netdom command line tool to create the trusts explained above.
For example, to create an external trust using Active Directory Domains and Trusts snap-in, follow the steps:
