McAfee MANAGEMENT EDITION 2.5 Administrator's Manual page 69

Small organizations can store accounts and resources in one domain.
However, large organizations usually establish multiple domains. They can
then store accounts in one domain and resources in another. A trust
relationship is a link between two Windows NT Server domains, providing
security across multiple domains. It combines two or more domains into one
administrative unit, allowing a user access to resources on the entire network
through a single user account and password. Users browsing the network for
available resources see the network grouped into domains, rather than as
individual servers and printers on the whole network.
Trust relationships let you use global groups and user accounts in domains
other than the domain where they are located. Therefore, the account can have
access to any computer on the network, not just the computers in one domain.
You can use trust relationships to specify trusting and trusted domains: A
trusting domain trusts network security to a trusted domain.
A trusting domain is the resource domain: It allows the users of a trusted
domain access to its resources. Only Windows NT Server domains can be
trusting domains.
A trusted domain is an account domain: It lists the domains that it trusts to use
its resources. Only Windows NT Server domains can be trusted domains.
Trusted-domain users and groups are allowed to hold user rights, resource
permissions and local group memberships in the trusting domains.
You can manage a machine in a non-trusted domain. For details, see
"Managing machines in a non-trusted Windows NT domain" on page
Follow these steps to create a trust relationship between two domains:
1. Obtain a password from the administrator of the domain that will be
trusted.
2. Start the User Manager for Domains.
3. If necessary, on the User menu, click Select Domain and complete the
Select Domain dialog box, specifying the name of your domain that will
be configured to trust the other domain.
4. On the Policies menu, click Trust Relationships.
