This lesson introduces you to trust relationships and the tasks involved in the management 70-297 practice test of trusts. In Chapter 1, you learned that a trust relationship is a link between two domains in which the trusting domain honors the logon authentication of the trusted domain. Trust relationships can be created automatically (implicitly) or manually (explicitly). Trust relationships created implicitly do not need management. In this lesson you learn how to plan, create, and administer explicit trust relationships.
Trust Relationships
A trust relationship is a logical relationship established between domains to allow pass-through authentication, in which a trusting domain honors the logon authentications of a trusted domain. There are two domains in a trust relationship—the trusting and the trusted domain.
In Windows NT, trusts are one-way and nontransitive, and can require a great deal of administrator maintenance. Trusts were limited to the two domains involved in the trust and the trust relationship was one-way. In Windows Server 2003, trusts have three characteristics.
Trusts can be created manually (explicitly) or automatically (implicitly).
Taists can be either transitive (not bound by the domains in the trust relationship) or nontransitive (bound by the domains in the trust relationship).
Trusts can be one-way or two-way.
Windows Server 2003 authenticates users and applications using MCSE required exams either the Kerberos version 5 or NTLM protocol. The Kerberos version 5 protocol is the default protocol for computers running Windows Server 2003. If any computer involved in a transaction does not support Kerberos version 5, the NTLM protocol is used.
When using the Kerberos version 5 protocol, the client requests a ticket from a domain controller in its account domain for presentation to the server in the trusting domain. This ticket is issued by an intermediary trusted by the client and the server. The client presents this trusted ticket to the server in the trusting domain for authentication.
When a client tries to access resources on a server in another domain using NTLM authentication, the server containing the resource must contact a domain controller in the client’s account domain to verify the account credentials. A trust relationship can also be created with any MIT version 5 Kerberos realm.
When a user is authenticated by a domain controller, the presence of a trust does not guarantee access to resources in that domain. Access to resources is determined solely by the rights and permissions granted to the user account by the domain administrator for the trusting domain. For information about providing access to resources free Microsoft exam papers, refer to Chapter 9, “Administering Active Directory Objects.”

Running Dcpromo on an existing domain controller allows you to remove free 70-297 test questions from the domain controller and demotes it to either a stand-alone server or a member server. If the domain controller is the last domain controller in the domain, it will become a stand-alone server. If other domain controllers will remain in the domain, it will become a member server. A stand-alone server is a computer that runs the Windows Server 2003 operating system but does not participate in a domain. It does not share account information with any other computer and cannot provide access to domain accounts. A member server is a computer that runs the Windows Server 2003 operating system and participates in a domain, but does not store a copy of the directory database. For a member server, permissions can be set on resources that allow users to connect to the server and use its resources.
If you remove Active Directory from all domain controllers in a domain, you also delete the directory database for the domain, and the domain no longer exists. Computers joined to this domain can no longer log on to the domain or use domain services.
To remove Active Directory, you must have administrative credentials as follows:
To remove Active Directory from a domain controller that is the last domain controller in a tree-root or a child domain, you must provide enterprise administrator
credentials or be a member of the Enterprise Admins group.
To remove Active Directory from a domain controller that is the last domain controller in the forest, you must log on to the domain as Administrator or as a member of the Domain Admins group.
To remove Active Directory from a domain MCSE required exams controller that is not the last domain controller in the domain, you must be logged on as a member of either the
Domain Admins group or the Enterprise Admins group.
Note Before you attempt to install Active Directory on a server, you must have an edition of Windows Server 2003 family installed and a static IP address configured for the server. Refer to Lesson 1 for instructions on configuring a static IP address for a server.
Because removing the last replica of an application directory partition will result in the permanent loss of any data contained in the partition, the Active Directory Installation Wizard will not remove application directory partitions unless you confirm the deletion.You must decide when it is safe to delete the last replica of a particular partition. If the domain controller holds a TAPI application directory partition, you may need to use the Tapicfg.exe command-line tool to remove the TAPI application directory partition. For more information on using free Microsoft questions, refer to Windows Server 2003 help.
