Both the Nltest and Netdom tools can be used to verify and reset MCTS certification secure channels between domain controller and domain member computers. If either utility indicates a secure channel doesn’t exist for the domain member computer, try the following:
1.Remove the computer from the domain by making it a member of a workgroup.
2.Delete the computer account from the Active Directory Users And Computers console.
3.Join the computer to the domain once again.
You are a computer consultant working for the Graphic Design Institute. In the past year you’ve helped the institute implement Active Directory in three different departments: Marketing, Administration, and Research. See the Case Scenario Exercises in Chapter 2 and Chapter 3 for more information about this company. Today, the company’s network infrastructure is host to three different forests.
The Information Technology Services (ITS) department is still running UNIX servers and hosting the company’s Internet connection. ITS has delegated the applicable DNS namespace for each domain to the Marketing, Administration, and Research depart-ments. Each department has its own network administration team.
Laura Steele, the director of the institute, wants to discuss some issues free 70-620 test questions she and the department directors have experienced.
Answer the following questions based on this information:
1. Right now, Research and Marketing are sharing data by burning CD-ROMs and DVD-ROMs. Under the current structure, how could Research and Marketing share information over the network?
Laura asks you, “What if we decided that ITS should handle the entire institute’s network administration? If we were building the entire administrative structure right now using Windows Server 2003 and Active Directory, how would it be different than what we have now?”
3. What are the potential issues of simply moving the management function of the existing structure to the ITS department, without modifying anything?
operations master A domain controller that has been assigned one or more special roles in an Active Directory domain. The domain controllers assigned these roles perform operations that are single-master (not permitted to occur at different places on the network at the same time).
selective authentication A method of setting the scope of authentication differently for outgoing and incoming external and forest trusts. Selective trusts allow you to make flexible access control decisions between external domains in a forest.
trust relationship A logical relationship established between domains to allow passthrough authentication, in which a trusting domain honors the logon authen?tications of a trusted domain. User accounts and global groups defined in a trusted domain can be given rights and permissions in a
free practice tests trusting domain, even though the user accounts or groups don’t exist in the trusting domain’s directory.

As an administrator, you must plan trust relationships to provide free 70-620 test questions users with the access to resources they require. When you add a Windows Server 2003 domain to an existing Windows Server 2003 forest, a tree-root or a parent-child trust is established automatically. Both of these trust relationships are two-way and transitive and are established at the time that the domain is created. Once established, these trust relationships do not need to be managed.
The four remaining types of trusts must be managed.
Accessing Resources Across Domains Joined by Shortcut Trust Using Active Directory Domains and Trusts, you can determine the scope of authentication between two domains that are joined by a shortcut trust. You can set selective authentication differently for out-going and incoming shortcut trusts, which allows you to make flexible access control deci-sions between domains. You set selective authentication on the Outgoing Trust Authentication Level page when you set up a shortcut trust using the New Trust Wizard.
If you use domain-wide authentication on the incoming shortcut trust, users in the second domain have the same level of access to resources in the local domain as users who belong to the local domain. For example, if Domain A has an incoming shortcut trust from Domain B and domain-wide authentication is used, any user from Domain B can access any MCTS certification resource in Domain A (assuming the user has the required permissions).
If you set selective authentication on an incoming shortcut trust, you need to manually assign permissions on each resource to which you want users in the second domain to have access. To do this, set an access control right Allowed To Authenticate on an object for that particular user or group from the second domain.
When a user authenticates across a trust with the Selective authentication option enabled, an Other Organization security ID (SID) is added to the user’s authorization data. The presence of this SID prompts a check on the resource domain to ensure that the user is allowed to authenticate to the particular service. Once the user is authenticated, if the Other Organization SID is not already present, the server to which the user authenticates adds the This Organization SID. Only one of these special SIDs can be present in an authenticated user’s context.
Administrators in each domain can add objects from one domain to access control lists (ACLs) on shared resources in the other domain. You can use the ACL editor to add or remove objects residing in one domain to ACLs on resources in the other domain. For more information about how to set permissions on resources, refer to Chapter 9, “Administering Active Directory Objects.”
Requirements To create a shortcut trust, you must have Enterprise Admin or Domain Admin privileges in both domains within the forest. Each trust is assigned a password that must be known to the free test questions administrators of both domains in the relationship.

This lesson introduces you to operations master 70-620 practice test roles and the tasks involved in the management of master role assignments. Operations master roles (also known as flexible single master operations, or FSMO) are special roles assigned to one or more domain controllers in an Active Directory domain. The domain controllers assigned these roles perform single-master replication. In this lesson, you learn how to plan operations master locations and to view, transfer, and seize operations master role assignments.

After analyzing your organization’s requirements, the first step in creating a domain TS windows vista plan is to determine the number of domains required. Because adding domains to the forest increases management and hardware costs, you should minimize the number of domains. Once you’ve created a domain, the domain cannot be easily moved or renamed. However, you might need to consider using multiple domains in the follow?ing situations:
To meet required security policy settings, which are linked to domains
To meet special administrative requirements, such as legal or privacy concerns
To optimize replication traffic
To retain Windows NT domains
To establish a distinct namespace
The second step in creating a domain plan is to define the forest root domain. You can choose an existing domain for the forest root or designate a new domain to serve as a dedicated forest root domain. Using a dedicated forest root domain provides advantages in security administration, replication traffic, and scalability. Define your forest root domain with caution, because once you’ve named the free 70-620 test questions forest root domain you cannot change it without renaming and reworking the entire Active Directory tree.
The third step in creating a domain plan is to define a domain hierarchy and name domains. To define the domain hierarchy, you must perform the following actions:
Determine the number of domain trees
Designate tree root domains for each of the trees
Arrange the remaining subdomains in a hierarchy under the root domains
To name domains, you must perform the following actions:
Assign a DNS name to the forest root domain for each forest in the organization
Assign a DNS name to each tree root domain
Assign DNS names to each remaining subdomain, according to its position in the
hierarchy
Finally, you determine the placement of DNS servers. You also plan additional zones, determine the existing DNS services employed on DNS servers, and determine the zone replication method to use. The end result of a domain plan is a domain hierarchy free CompTIA IT certification test questions diagram that includes domain names and planned zones.

Active Directory allows users and administrators to find objects such as files, printers, or users in their own free 70-620 test questions. However, finding objects outside of the domain and across the enterprise requires a mechanism that allows the domains to act as one entity. A catalog service contains selected information about every object in all domains in the directory, which is useful in performing searches across an enterprise. The global catalog is the catalog service provided by Active Directory.
The global catalog is the central repository of information about objects in a tree or forest. By default, a global catalog is created automatically on the initial domain controller in the first domain in the forest. A domain controller that holds a copy of the global catalog is called a global catalog sewer. You can designate any domain controller in the forest as a global catalog server. Active Directory uses multimaster replication to replicate the global catalog information between global catalog servers in other domains. It stores a full replica of all object attributes in the directory for its host domain and a partial replica of all object attributes contained in the directory for every domain in the forest. The partial replica stores attributes most frequently used in search operations (such as a user’s first and last names, logon name, and so on). Attributes are marked or unmarked for replication in the global catalog when they are defined in the Active Directory how to get windows vista for free. Object attributes replicated to the global catalog inherit the same permissions as in source domains, ensuring that data in the global catalog is secure.
When a user logs on to the network, the global catalog provides universal group membership information for the account to the domain controller processing the user logon information. If there is only one domain controller in a domain, the domain controller holds the global catalog server. If there are multiple domain controllers in the network, one domain controller is configured to hold the global catalog. If a global catalog is not available when a user initiates a network logon process, the user is able to log on only to the local computer unless the site has been specifically configured to cache universal group membership lookups when processing user logon attempts.
