You can use the Active Directory Domains and Trusts snap-in to create external trusts. replication, choose the Networking & In this lesson, you find out how to configure trusts between two different forests, between two separate domains in different forests, and between a domain and a Kerberos realm. Users in the ExampleTree.local domain will not be able to authenticate to resources in Example.com, unless the name suffix route for ExampleTree.local is enabled on the trust object in Example.com.
