What is a domain controller?
Domain Controller it is Microsoft Windows Server 2000/2003 directory server that provides access controls over users, accounts, groups, computers and other network resources. Domain Controller authenticate users and maintains directory services and the security database for a domain.
What is the difference between a single-master and a multi-master domain replication model?
Multi-master replication is a replication model in which any domain controller accepts and replicates directory changes to any other domain controller. Because multiple domain controllers are employed, replication continues, even if any single domain controller stops working.Single-master replication is a replication model in which one domain controller accepts and replicates directory changes to any other domain controller. This master domain controller is known as "Operation Master".Multi-master replication is a method of database replication which allows data to be stored by a group of computers, and updated by any member of the group.The multi-master replication system is responsible for propagating the data modifications made by each member to the rest of the group, and resolving any conflicts that might arise between concurrent changes made by different members.Multi-master replication can be contrasted with master-slave replication, in which a single member of the group is designated as the "master" for a given piece of data and is the only node allowed to modify that data item. Other members wishing to modify the data item must first contact the master node. Allowing only a single master makes it easier to achieve consistency among the members of the group, but is less flexible than multi-master replicationFlexible Single Master of Operation or just single master operation or operations master, is a feature of Microsoft's Active Directory (AD).FSMOs are specialized domain controller tasks, used where standard data transfer and update methods are inadequate. AD normally relies on multiple peer DCs, each with a copy of the AD database, being synchronized by multi-master replication. The tasks which are not suited to multi-master replication, and are viable only with a single-master database, are the FSMOs.Once per domain they only replicate to allThe Relative ID Master allocates security RIDs to DCs to assign to new AD security principals (users, groups or computer objects). It also manages objects moving between domains.The Infrastructure Master maintains security identifiers, GUIDs, and DN for objects referenced across domains. Most commonly it updates user and group links.This is another domain-specific role and its purpose is to ensure that cross-domain object references are correctly handled. For example, if you add a user from one domain to a security group from a different domain, the Infrastructure Master makes sure this is done properly. As you can guess however, if your Active Directory deployment has only a single domain, then the Infrastructure Master role does no work at all, and even in a multi-domain environment it is rarely used except when complex user administration tasks are performed. Because of this, the hardware requirements for machines holding this role are relatively small.The PDC Emulator operations master role processes all password changes in the domain. Failed authentication attempts due to a bad password at other domain controllers are forwarded to the PDC Emulator before rejection. This ensures that a user can immediately login following a password change from any domain controller, without having to wait several minutes for the change to be replicated. The PDC Emulator Operations Master role must be carefully sited in a location to best handle all password reset and failed-authentication forwarding traffic for the domain. The PDC emulator role holder retains the following functions:1.Password changes performed by other DCs in the domain are replicated preferentially to the PDC emulator.2.Authentication failures that occur at a given DC in a domain because of an incorrect password are forwarded to the PDC emulator before a bad password failure message is reported to the user.3.Account lockout is processed on the PDC emulator.4.backward compatibility,The PDC emulator performs all of the functionality that a Microsoft Windows NT 4.0 Server-based PDC or earlier PDC performs for Windows NT 4.0-based or earlier clients.Once per forestThe Schema Master maintains all modifications to the schema of the forest. The schema determines the types of objects permitted in the forest and the attributes of those objects.The Domain Naming Master tracks the names of all domains in the forest and is required to add new domains to the forest or delete existing domains from the forest. It is also responsible for group membership.
What are domains?
the word domain is used in the context of a domain naming system. The word domain naming system is commonly abbreviated as DNS. For a domain naming system, the word domain is defined as a group of workstations and servers which share a single group name. The word domain also refers to the address of a website on the Internet. The protocol, the path, the page and the other items are not attached to the domain. by harideep
When a client computer sends a request to a Domain Name System (DNS) server, what type of packet is sent?
DNS primarily uses the User Datagram Protocol (UDP) on port number 53 to serve requests. DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. When the length of the answer exceeds 512 bytes and both client and server support EDNS, larger UDP packets are used.
What is the word definition for website?
The definition of a website is a computer connected to the internet that maintains a series of the web pages on the World Wide Web. It can also be defined as a set of the related web pages that are served from a single web domain.
What is the single domain system?
A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.domain is security boundary for all the resources in the network like pc,printer etc. so a single domain system is one which has only one domain in the forest eg.. xyz.com and no other domain in the forest except xyz.com.
What is forest and domain?
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.
What is the systems domain?
A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.domain is security boundary for all the resources in the network like pc,printer etc. so a single domain system is one which has only one domain in the forest eg.. xyz.com and no other domain in the forest except xyz.com.
Which naming context contains forest wide data about the physical topology of an active directory forest?
Active Directory NC (Naming Context's)Active Directory consists of three partitions or naming contexts (NC) Domain, Configuration and Schema Naming ContextsEach are replicated independentlyAn Active Directory forest has single schema and configuration Every domain controller (DC) holds a copy of each (schema, configuration NC's)Forest can have multiple domains Every domain controller in a domain holds a copy of the domain NC
The key is good for a single installation.?
The key is good for a single installation.
What naming contexts are replicated across an entire active directory forest?
Active Directory NC (Naming Context's)Active Directory consists of three partitions or naming contexts (NC) Domain, Configuration and Schema Naming ContextsEach are replicated independentlyAn Active Directory forest has single schema and configuration Every domain controller (DC) holds a copy of each (schema, configuration NC's)Forest can have multiple domains Every domain controller in a domain holds a copy of the domain NC
What is Active directory Naming Context?
Active Directory NC (Naming Context's) * Active Directory consists of three partitions or naming contexts (NC) ** Domain, Configuration and Schema Naming Contexts * Each are replicated independently * An Active Directory forest has single schema and configuration ** Every domain controller (DC) holds a copy of each (schema, configuration NC's) * Forest can have multiple domains ** Every domain controller in a domain holds a copy of the domain NC
Can you have two domains on server 2003?
You can't have two domains on the same server 2003 machine, since it has to manage a single domain. However, you can have many domains in a server 2003 forest or a series of trees, which are managed by a forest controller. And, a single server 2003 can manage multiple domains.
What is the use of root domains?
I have a domain DomainA.com and X.DomainA.com is it consider a single domain or multiple domain?
Who is responsible for establishing a single installation wide emergency program?
Installation Commander
What are FMSO Servers?
Flexible Single Master Operations servers. They are servers that every Active Directory needs that serve a single purpose. Here are the FSMO servers: Schema Master Domain Naming Master Infrastructure Master Relative ID Master PDC Emulator Those are the five FSMO server rolls that get assigned to 1 or more domain controllers in each domain. Schema and Domain Naming Master will have only 1 server per AD Forest.
How many collision and broadcast domain are there if a router is directly connected to hub?
A hub contains a single collision domain and a single broadcast domain, regardless of the number of ports on the hub.
