one needs to make trust between the domains. please check below the different types of the trusts

One-way trust

One domain allows access to users on another domain, but the other domain does not allow access to users on the first domain.

Two-way trust

Two domains allow access to users on both domains.

Trusting domain

The domain that allows access to users from a trusted domain.

Trusted domain

The domain that is trusted; whose users have access to the trusting domain.

Transitive trust

A trust that can extend beyond two domains to other trusted domains in the forest.

Intransitive trust

A one way trust that does not extend beyond two domains.

Explicit trust

A trust that an admin creates. It is not transitive and is one way only.

Cross-link trust

An explicit trust between domains in different trees or in the same tree when a descendant/ancestor (child/parent) relationship does not exist between the two domains.

Shortcut

Joins two domains in different trees, transitive, one- or two-way

Forest

Applies to the entire forest. Transitive, one- or two-way

Realm

Can be transitive or nontransitive, one- or two-way

External

Connect to other forests or non-AD domains. Nontransitive, one- or two-way.

Windows 2000 Server supports two-way transitive and one-way intransitive trusts. Administrators can create shortcuts.

Windows Server 2003 the forest root trust. This trust can be used to connect Windows Server 2003 forests if they are operating at the 2003 forest functional level. Authentication across this type of trust is Kerberos based (as opposed to NTLM). Forest trusts are transitive for all the domains in the trusted forests. Forest trusts, however, are not transitive.

Domains can be very complicated. If you create diffrent names for the domains it can couse issues in connectivity. The primary Domain controller should have the Base line name of the entire forest(All of the computers in a network) When creating second domains they can have subnames. Example: Primary domain controller is called Contoso.com, When adding other domain controllers they should look like this: Contoso.xyz.com If you create a domain with a completely diffrent name it will not be able to join the primary domain. If you create all the domain controllers with the exact same name then they will not know what to connect to or witch one is primary


No the reason it's called a primary Domain Controller is because it's the one controller that has all the domain names and address for that Domain.


Windows Server 2003 interimSupported domain controllers: Windows NT 4.0, Windows Server 2003Supported features: There are no domain-wide features activated at this level. All domains in a forest are automatically raised to this level when the forest level increases to interim. This mode is only used when you upgrade domain controllers in Windows NT 4.0 domains to Windows Server 2003 domain controllers.


There are several examples of domains... Domain Bacteria Domain Archaea Domain Eukarya which consists of different kingdoms: Protists Plantae Fungi Animalia


Child Domains are created under Parent Domain So Parent Domain IS the Master Domain Controller

A broadcast domain is created any time you connect several clients together via a network connectivity device, such as a hub or switch or bridge. They would all be in the same broadcast domain for every client connected to them. Since a router does not forward broadcast messages, it creates different broadcast domains.


Domains are oganized in different extensions.Check this http://compnetworking.about.com/od/dns_domainnamesystem/a/domain-name-tld.htm


Add-on domain are sub domains, This means that you can host multiple domains with different content on a single web hosting account. It also allows to use the same web space and bandwidth of the main domain hosted.


Domain Archaea, and Domain Bacteria.


No, Domains only provide you a name and a unique identity to your website. Domains are for individual websites. You need to have a internet connection to connect to internet. It is provided by ISP(s) in your region. You as an individual cannot setup your own infrastructure to connect to internet. You need to use someone else.


Vertical domains are only for applications within a specific domain or closely related domains. Horizontal domains are applicable across the board for applications regardless of the domain.

the root domainDNS namespace: DNS is the name service provided by the Internet for TCP/IP networks. DNS is broken up into domains, a logical organization of computers that exist in a larger network. The domains exist at different levels and connect in a hierarchy that resembles the root structure of a tree. Each domain extends from the node above it, beginning at the top with the root-level domain. Under the root-level domain are the top-level domains, under those are the second-level domains, and on down into subdomains. DNS namespace identifies the structure of the domains that combine to form a complete domain name. For example, in the domain name sub.secondary.com, "com" is the top-level domain, "secondary" identifies the secondary domain name (commonly a site hosted by an organization and/or business), and "sub" identifies a subdomain within the larger network. This entire DNS domain structure is called the DNS namespace. The name assigned to a domain or computer relates to its position in the namespace.


Three is the number of maximum hops between domain controllers


Domain and kingdom are different because the domain tells you if the cell has nuclei or not (eukaryote). The Kingdom tells you if it is a plant, animal, or fungi.


Contains a domain > container (for example, the abc.com container), which stores users, computers, groups, and other objects for a specific Windows domain (for example, the abc.com domain). Updates to the domain > container are replicated to only domain controllers within the domain and to Global Catalog servers if the update is made to an attribute that is marked for replication to the Global Catalog. The domain > container is displayed in the Active Directory Users and Computers console. The hierarchy of domain directory partitions can be viewed in the Active Directory Domains and Trusts console, where trust relationships between domains can be managed.


A piece-wise continuous function is one which has a domain that is broken up inot sub-domains. Over each sub-domain the function is continuous but at the end of the domain one of the following possibilities can occur:the domain itself is discontinuous (disjoint domains),the value of the function is not defined at the start or end-point of the domain ((a hole),the value of the function at the end point of a sub-domain is different to its value at the start of the next sub-domain (a step-discontinuity).A piece-wise continuous function is one which has a domain that is broken up inot sub-domains.

A domain as "a single security boundary of a Windows NT-based computer network. Active Directory is made up of one or more domains. On a standalone workstation, the domain is the computer itself. A domain can span more than one physical location. Every domain has its own security policies and security relationships with other domains. When multiple domains are connected by trust relationships and share a common schema, configuration, and global catalog, they constitute a domain tree. Multiple domain trees can be connected together to create a forest." Domain A Windows domain is a collection of security principals that share a central directory database. This central database (known as Active Directory starting with Windows 2000,[1] Active Directory Domain Services in Windows Server 2008 and Server 2008 R2, also referred to as NT Directory Services on Windows NT operating systems, or NTDS) contains the user accounts and security information for the resources in that domain. Each person who uses computers within a domain receives his or her own unique account, or user name. This account can then be assigned access to resources within the domain. In a domain, the directory resides on computers that are configured as "domain controllers." A domain controller is a server that manages all security-related aspects between user and domain interactions, centralizing security and administration. A Windows Server domain is generally suited for businesses and/or organizations when more than 10 PCs are in use. Trust To allow users in one domain to access resources in another, Active Directory uses trusts. Trusts inside a forest are automatically created when domains are created. The forest sets the default boundaries of trust, and implicit, transitive trust is automatic for all domains within a forest. Terminology One-way trust One domain allows access to users on another domain, but the other domain does not allow access to users on the first domain. Two-way trust Two domains allow access to users on both domains. Trusting domain The domain that allows access to users from a trusted domain.

Intransitive trust A one way trust that does not extend beyond two domains. Explicit trust A trust that an admin creates. It is not transitive and is one way only. Cross-link trust An explicit trust between domains in different trees or in the same tree when a descendant/ancestor (child/parent) relationship does not exist between the two domains.

A domain is a logical grouping of devices in a single name and can be administered as a group. Domains are assigned to companies or subdivisions within companies. A forest is a collection of domain trees. A forest could contain domains from multiple sites, such as a parent company maintaining control over several acquired companies with different domain names.


A bridge typically creates separate collision domains within the same broadcast domain. If you take a bridge with 2 ports, each port connects to a LAN segment that is in its own collision domain. Therefore, for a 2 port bridge you will get 2 different collision domains.


A TreeTrees are collections of one or more domains that allow global resource sharing. A tree may consist of a single domain or multiple domains in a contiguous namespace. Adding a domain to a tree becomes a child of the tree root domain. Domain will be called as parent domain to which child domain is attached. A child domain can also have its multiple child domains. Child domain uses the name followed by parent domain name and gets a unique Domain Name System (DNS).For example, if tech.com is the root domain, you can create one or more Child domains to tech.com such as north.tech.com and or south.tech.com. These "children" may also have child domains created under them, such as sales.north.tech.com.The domains in a tree have two-way, Kerberos transitive trust relationships. A Kerberos transitive trust simply means that if Domain A trusts Domain B and Domain B trusts Domain C, then Domain A trusts Domain C. Therefore, a domain joining a tree immediately has trust relationships established with every domain in the tree.
