Click the Windows 'Start' button and select 'All Programs.' Click 'Administrative Tools' and click 'Active Directory Domains and Trusts.' This opens the main console for the domain.
Right-click the domain forest unit on the left side of the window. In the menu, select 'Properties.' Click the 'Trust' tab to establish the trust.
Click 'New Trust' and click 'Next' in the opening window. In the 'Trust Name' text box, enter the domain you want to trust. In the 'Trust Type' section, enter 'Forest trust.'
Select the direction of the trust. A 'two-way' trust allows both domains to trust each other, which means users can share resources both ways. A one-way trust only allows the trusted domain to share resources, but users on the current domain are unable to access the other domain's resources.
Click 'Continue' at the final summary screen. Close the domain manager to finalize the configurations.
