Active Directory Benefits
The biggest difference between these two server operating systems and Windows NT is the addition of Active Directory. Although there is a bit of a learning curve associated with implementing an Active Directory environment, the benefits of doing so far outweigh the negatives.
A better representation of the network
Centralization sums up my primary reason for implementing Active Directory. The Active Directory structure makes it possible for you to achieve truly centralized management of users, regardless of how big your client’s network has become. If you've worked with Windows NT before, you know that in Windows NT a domain is a completely independent entity. While it's possible to create a trust relationship between domains that exist on a common network, the domains are never truly integrated with each other because there is no higher authority that manages the domains.
Seeing through the forest
The situation is different with Active Directory. Whereas the domain level was the highest level of abstraction in Windows NT, the highest level of abstraction in Windows 2000 and 2003 Server is the forest, which is basically a collection of domains. Microsoft chose to call this unit a forest because you can place domains into the forest, and you can place entire trees of domains into it. A domain tree consists of a parent, child, grandchildren, and great grandchildren domains. You can have as many layers of subdomains within a domain tree as is necessary to achieve the desired organizational structure.

The Active Directory domain structure is handy to have whether your client’s network is big or small. As you may recall, in Windows NT, each domain had its own Administrator account and its own Domain Admin group that was responsible for managing that domain. In Windows 2000 and 2003 Server, the domain Administrator account and the Domain…...

...Riordan Active Directory Migration Tyler Dresslar POS 421 September 3, 2012 R.Chung Riordan Active Directory Migration Introduction With regards to Riordan Manufacturing acquiring new severs with Active Directory Technology, the company must look at migrating to Windows Server 2008 R2 in order facilitate the streamlining of work for the Information Technology Department. Moving to Active Directory will save Riordan TIME and MONEY, the benefits of such a move and implementation will be explained in the following paragraphs. Microsoft Active Directory Domain Services are the foundation for distributed networks built on Windows 2000 Server, Windows Server 2003 and Microsoft Windows Server 2008 operating systems that use domain controllers. Active Directory Domain Services provide secure, structured, hierarchical data storage for objects in a network such as users, computers, printers, and services. Active Directory Domain Services provide support for locating and working with these objects. Windows 2000 Server and later operating systems provide a user interface for users and administrators to work with the objects and data in Active Directory Domain Services. Network administrators write scripts and applications that access Active Directory Domain Services to automate common administrative tasks, such as adding users and groups, managing printers, and setting permissions for network resources. Independent software vendors and end-user developers can use......

Active Directory Benefits

...One of the benefits of moving an organization to an Active Directory environment is the use of trees and forests. Trees are groups of one or more domains who share resources. Each domain within the tree trusts the other domains in areas of security. A domain added to a tree becomes a child of that tree root domain. These trees can then become a part of a forest. A forest is a collection of numerous trees who share a common large-scale catalog, directory outline, logical structure, and directory arrangement. Forests permit organizations to group their divisions that may need to operate self-sufficiently and use different naming patterns, but still need to communicate with the entire organization through trustworthy sites and share some of the same resources. This allows the organization to reduce costs without added complication and have greater security. (1) Another benefit would be user management. Due to active directory’s forest design, users in one domain are known to the forest domain director. This provides for more flexibility and ease of access for users who must travel from one site to another. A user can travel from site 1 to site 2 and still be able to log in with their usual username and password and have access to all resources throughout the domain. (2) Another useful tool within active directory is group policy. Say you have an employee or group of employees who don’t necessarily follow your rules for computer use. They change their CPU’s desktop......

...1. Benefits of directory services (AD DS) Without getting too technical and wordy, but being able to help the client understand more about what active directory does, the following can be explained: - AD shows a better representation of the network by a process known as centralization. Centralization is the process of managing users regardless of the size of the network in one location. - Utilizes organizational units to improve scalability. If an organization is large, OUs can help simplify the task by grouping resources (such as users and computers) that have similar rights. - Replication makes it easier because any changes that are made are replicated to other domain controllers so that the network can run more efficiently. http://www.techrepublic.com/article/the-benefits-of-moving-clients-to-an-active-directory-environment/ Active Directory Domain Services (AD DS) benefits: Redundancy Fault Tolerance Serves as a domain controller that authenticates users when logging on to a network.

...Based on the Active Directory implementation plan that I provided in the week two discussions, I wanted to create a plan that created strategies that would separate or let you know who users in which groups using Windows material are. I want to show that nesting a plan like this will be easier on the user, administrator, and company. Groups these days are used to keep users, connected parts, and everyone that is part of the domain. The administrator or Point of Contact can make things a lot easier when they use groups or grouping. Everything that is stored in the computer’s system from employee start date to age to termination, etc. is stored in the groups. (Microsoft TechNet, 2007) All the groups and users will have the same setting for security and permissions. There are a few groups that can be used. The types of groups we will use here are distribution groups and Security groups. The distribution groups will be used with all email applications for emails to be sent/received to all other users in that email list. Each group will be allowed to access the network. They can also give rights to users in the Active Directory and set different security issues on the network. Distribution and groups are made by the scope with a domain. The groups for Riordan will be local. It gives access to domains and security. (Cooper, 2011) An example of this would be any user or member using the domain. Usually members of this group do not change. The other groups usually......

...To back up Active Directory, you must install the Windows Server Backup feature from the Server Manager console. To perform backups from the command line, you will also need to install Windows PowerShell. Windows Server Backup supports the use of the disk drives as backup destinations. Windows Server 2008 supports two types of backup: • Manual backup: This type of backup can be initiated by using Server Backup or the Wbadmin.exe command-line tool when a backup is needed. You must be a member of the Administrators group or the Backup Operators group to launch a manual backup. • Scheduled backup: Members of the local Administrators group can schedule backups using the Windows Server Backup utility or the Wbadmin.exe command-line tool. Scheduled backups will reformat the desired drive that hosts the backup files, and can only be performed on a local physical drive that does not have any critical volumes. With all this taken into consideration I would perform a manual backup every time a major change is taking place and then use a scheduled backup every month to make sure every small change is saved and is not over looked. When a domain has multiple domain controllers, the Active Directory database is replicated within each domain controller. Windows Server 2008 allows several different restoration methods, depending on the goals for your restore. Wbadmin, is the command-line component of the Windows Server Backup snap-in, which restores a single Active Directory domain......

Active Directory Rights Management Services i. Active Directory Federation Services is a standards-based service that allows the secure sharing of identity information between business partners (know as federations) across the extranet. When a user needs to access a Web application from one of its federation partners, the users own organization is responsible for authenticating the user and providing identity information in the form of "claims" to the partner that hosts the Web application. The hosting partner uses its trust policy to map the incoming claims to claims that are understood by its Web application, which uses the claims to make authorization decisions. ii.

The first way that they would backup there computer that use the Active Directory is by using a Manual backup. The way that they would go by doing that would be going into the computer and open up the Administrators group or the Backup Operators group to launch a manual backup on their computers in the office. The other that they would backup there computer is by doing a schedule backup. They would have to go through the Administrators group on the computer then they would have to schedule a backup by picking when they would want the backup to start and what date they would like it on. They would also have to pick what files they would want to be saving and what drive they would like to be backup. The way to have a recovery plan for the Active Directory they would have to do a restore on the Active Directory because that is the only way to bring it back.

Active Directory

...Project- Windows 2012 Management 12/5/14 Active Directory is a directory service that Microsoft developed for Windows domain networks and is included in most Windows Server operating systems as a set of processes and services. An Active Directory domain controller authenticates and allows all users and computers in a Windows domain type network- assigning and enforcing security policies for all computers and installing or updating software. When a user logs into a computer that is part of a Windows domain, Active Directory checks the submitted password and determines whether the user is a system administrator or normal user. Active Directory makes use of Lightweight Directory Access Protocol (LDAP) versions 2 and 3, Microsoft's version of Kerberos, and DNS. Active Directory, like many information-technology efforts, originated out of a democratization of design using Request for Comments or RFCs. The Internet Engineering Task Force (IETF), which oversees the RFC process, has accepted numerous RFCs initiated by widespread participants. Active Directory incorporates decades of communication technologies into the overarching Active Directory concept then makes improvements upon them. Microsoft previewed Active Directory in 1999, it was first released with Windows 2000 Server edition, and revised it to extend functionality and improve administration in Windows Server 2003. Additional improvements came with Windows Server 2003 R2, Windows Server 2008, and......

Benefits of Active Directory

...Unit 8 Assignment 2 Benefits of Active Directory An Active Directory structure is a hierarchical arrangement of information about objects. The objects fall into two broad categories: resources (e.g., printers) and security principals (user or computer accounts and groups). Security principals are assigned unique security identifiers (SIDs). Each object represents a single entity—whether a user, a computer, a printer, or a group—and its attributes. Certain objects can contain other objects. An object is uniquely identified by its name and has a set of attributes—the characteristics and information that the object represents— defined by a schema, which also determines the kinds of objects that can be stored in Active Directory. The schema object lets administrators extend or modify the schema when necessary. However, because each schema object is integral to the definition of Active Directory objects, deactivating or changing these objects can fundamentally change or disrupt a deployment. Schema changes automatically propagate throughout the system. Once created, an object can only be deactivated—not deleted. Changing the schema usually requires planning. Sites are physical (rather than logical) groupings defined by one or more IP subnets. AD also holds the definitions of connections, distinguishing low-speed (e.g., WAN, VPN) from high-speed (e.g., LAN) links. Site definitions are independent of the domain and OU structure and are common across the...

Using Active Directory and Establishing a Group Policy should solve all your problems with employees. Active Directory will keep track of all the user accounts. You can establish accounts for each employee and put them into groups based on how much permission they need. I recommend giving only what permission is needed. You can use the Access Control List to assign a degree of permission. Keep in mind that if a user is in more than one group they will only receive the lowest permission level. You can use these tools to control what a user can change on their computer and even when they can log on. Active Directory can also control what can be downloaded on a computer. I also recommend checking the firewall settings to make sure that certain programs cannot be used. Changing these settings could prevent users from downloading viruses on the computer. You can create a default setting that will show up on all workstations. The Group Policy Management tool will help with assigning these permissions. You can use Active Directory Sites and Services to replicate data on all sites. Network Load Balancing will help with the internet being slow by distributing the work load to several servers.
