A trust relationship allows one Windows domain or forest to trust another. This allows users in one domain or forest to access resources in another domain or forest as if they were in their own. To check if a trust relationship exists between two domains or forests, you can use the following steps:
1. Open the Active Directory Users and Computers console.2. In the console tree, expand the domain or forest that you want to check.3. Right-click the Trusts container and select Properties.4. In the Trust Relationships tab, you will see a list of all the trust relationships that exist for the selected domain or forest.
