Causes Of The Windows Active Directory Domain Error In Windows

The Active Directory Domain Services Is Currently Unavailable error means that a computer system can’t find or connect to the printer. The error halts the printing process and doesn’t allow the command to go through.

The Active Directory Domain Services are the core functions that allow a computer to authorize and authenticate commands and directions. For example, the Active Directory allows a computer to confirm that the password entered to access it is correct and determine if the user has administrative privileges. It also allows a computer to store and manage data, and connect with external devices such as wireless routers and printers.

Add A Domain Controller To An Existing Domain In Windows Server 2016

The procedures for adding a domain controller to an existing domain in Active Directory are the same, no matter which operating system you have. However, these instructions were organized during an exercise on Windows Server 2016. It is always a good idea to have at least two domain controllers in your AD domain just in case one goes down.

The second Domain Controller is a separate computer from the one identified for your first Domain Controller. That second computer needs to be set up with Windows Server 2016. Get it fully patched and assign it an IP address before starting the AD setup on that machine. Then follow these steps:

  • Open Server Manager, click on the Manage option on the menu ribbon and select Add Roles and Features.
  • In the opening screen of the wizard, click on Next.
  • In the Installation Type screen select the Role-based or feature-based installation radio button and click on Next.
  • In Server Selection leave the only server in the list highlighted and press Next.
  • In the Server Roles screen, Check the Active Directory Domain Services box. A dialogue box appears. Click on the Add Features button.
  • Back in the main feature selection screen, click the Next button.
  • This cycles through to the Features screen. Just click on the Next button. In the AD DS screen, click on the Next button.
  • Enter the username and password of the Administrator account on the AD instance that you first set up. This username should be in the format < domain> \Administrator. Click OK.

    Convert Dns Zones To Active Directory Integrated

    Before we move on to AD DS configuration, lets convert the DNS zones we created earlier to Active Directory integrated zones. The steps below will guide you through the task.

    • From Server Manager, Open DNS. Expand the Server Name, then expand Forward Lookup Zones. Finally, right-click your forward lookup zone name and select Properties.
    • Beside Primary, click Change. Check the box Store the zone in Active Directory...Then click Ok. Click Yes to confirm.

    Repeat the task for the Reverse Lookup Zone.

    Next, configure Secure Dynamic updates. On the Properties of the zone, General tab, click the drop-down beside Dynamic updates. Select Secure Only. Finally, to save your changes click Ok.

    How Do You Secure Active Directory

    AD is critical to maintaining data security and compliance with data privacy regulations like GDPR, CCPA, and HIPAA. Attackers know how to infiltrate, escalate privileges, perform reconnaissance, and cover their tracks in AD. It is incumbent upon admins to know those same tricks and make their networks as hard to crack as possible.

    Here are a few tips from the Active Directory Security Best Practices blog.

  • Document everything about AD: To keep a clean and secure AD, you must know everything about that AD and I do mean everything. Document naming conventions and key security policies in addition to every user, service account, computer, and access group.
  • Enforce Safe Practices Among Users: Enforce strong passwords, train users to recognize phishing attacks, lock users out of making changes that can compromise security, limit access to make administrative changes to a few secured systems
  • Max security on DCs: Configure the network so admins only access DCs from a hardened terminal. If an attacker gains access to a DC they win.
  • Monitor AD: Track every change, every login, every group add.
  • There is much more to AD security than those four points, but they are a place to start so you can begin to manage the rest.

    Active Directory Domain Services Administration

    Any systems administrator will agree that Active Directory Domain Services offers comprehensive services for network administration. In fact, AD DS goes beyond the simple Lightweight Directory Access Protocol services most manufacturers publish. An LDAP service is designed to provide an organized set of records, often using a hierarchical structure. For example, a phone book is a simple directory.

    Active Directory Domain Services is a directory service that provides a means of securing and managing a Windows network. It also supports links and integration features with other Windows-based services. Because of this, AD DS is the primary directory that is designed to rule and manage users, computers and servers in a distributed network hierarchy.

    However, AD DS is first and foremost based on a database a hierarchical database . As such, the directory database contains a schema a database structure. This schema applies to every instance of AD DS, but it can be extended as when you integrate directory aware applications such as Microsoft Exchange, Microsoft SharePoint and other into your network structure.

    Domain contents can be further categorized through grouping object types such as organizational units or groups. Organizational units provide groupings that can be used for administrative or delegation purposes. Groups are used mainly for the application of security rights or email distribution lists.

    How To Setup A Domain Controller

    One of the first things you need to do when using Active Directory is to set up a domain controller. A domain controller is a central computer that will respond to authentication requests and authenticate other computers throughout the network. The domain controller stores the login credentials of all other computers and printers.

    All other computers connect to the domain controller so that the user can authenticate every device from one location. The advantage of this is that the administrator wont have to manage dozens of login credentials.

    The process of setting up a domain controller is relatively simple. Assign a static IP address to your Domain Controller and install Active Directory Domain Services or ADDS. Now follow these instructions:

  • Open Server Manager and click Roles Summary > Add roles and features.
  • Click Next.
  • Select Remote Desktop Services installation if youre deploying a domain controller in a virtual machine or select role-based or feature-based installation.
  • Select a server from the server pool.
  • Select Active Directory Domain Services from the list and click Next.
  • Leave the Features checked by default and press Next.
  • Click Restart the destination server automatically if required and click Install. Close the window once the installation is complete.
  • Once the ADDS role has been installed a notification will display next to the Manage menu. Press Promote this server into a domain controller.
  • When the DNS Options page displays click Next again.

    Active Directory Domain Services

    There are several benefits to using AD DS for your basic network user and computer management.

    • You can customize how your data is organized to meet your companies needs
    • You can manage AD DS from any computer on the network, if necessary
    • AD DS provides built in replication and redundancy: if one Domain Controller fails, another DC picks up the load
    • All access to network resources goes through AD DS, which keeps network access rights management centralized

    What Are Active Directory Domain Services

    Active Directory Domain Services are a core component of Active Directory and provide the primary mechanism for authenticating users and determining which network resources they can access. AD DS also provides additional features such as Single Sign-On , security certificates, LDAP, and access rights management.

    What Are Ad Sites

    AD sites are used for managing organizations that have branches spread across different geographical locations but fall under the same domain. It is a robust solution to geographically manage an AD network without changing any aspect of the logical structure of the environment. AD sites are physical groupings of well-connected IP subnets that are used to replicate information among domain controllers efficiently. AD sites can be imagined as a map that describes the best routes for carrying out replication in AD, thus making efficient use of the available network bandwidth. AD sites help to achieve cost-efficiency and speed. It also lets one exercise better control over the replication traffic and the authentication process. When there is more than one DC in the associated site that is capable of handling client logon, services and directory searches, AD sites can locate the closest DC to perform these actions. Sites also play a role in the deployment and targeting of group policies.In AD, the information about the topology is stored as site link objects. By default, the Default-First-Site-Name site container is created for the forest. Until another site is created, all DCs are automatically assigned to this site.

    Working Of Azure Active Directory Domain Services

    Active Directory Diagrams Solution

    Azure Active Directory Domain Services integrate with your existing applications and migrated workloads to provide identity services in the cloud. A pair of Windows Server domain controllers manage the Azure Virtual Machines to provide you with a synchronized hybrid environment. The domain services perform one-way synchronization from on-premise directory to the Azure Ad tenant using Azure AD Connect. The resources created on Azure Domain Services are not synced with Azure AD Directory Services.

    You can also deploy Azure Active Directory Domain Services for cloud-only organizations by positioning a Virtual Network and a dedicated subnet within it. Microsoft creates two Domain Controllers in the subnet and allows you to use Azure AD Domain Services features like domain join, LDAP read, LDAP bind, Group Policy and authentication of NTLM and Kerberos. Configuration of Azure AD Connect is not required as there is no need for identity synchronization.

    Benefits Of Active Directory

    Active Directory simplifies life for administrators and end users whileenhancing security for organizations. Administrators enjoy centralized userand rights management, as well as centralized control over computer and user configurations through the AD Group Policy feature. Users can authenticateonce and then seamlessly access any resources in the domain for whichtheyre authorized . Plus, files are stored in a centralrepository where they can be shared with other users to ease collaboration,and backed up properly by IT teams to ensure business continuity.

    How does Active Directory work?

    Its important to understand that Active Directory is only foron-premises Microsoft environments. Microsoft environments in the cloud useAzure Active Directory, which serves the same purposes as its on-premnamesake. AD and Azure AD are separate but can work together to some degree ifyour organization has both on-premises and cloud IT environments .

    How is Active Directory structured?

    AD has three main tiers: domains, trees and forests. A domain is a group ofrelated users, computers and other AD objects, such as all the AD objects foryour companys head office. Multiple domains can be combined into atree, and multiple trees can be grouped into a forest.

    What Services Are Provided In Active Directory Domain Services

    Here are the services that AD DS provides as the core functionality required by a centralized user management system.

    • Domain Services: Stores data and manages communications between the users and the DC. This is the primary functionality of AD DS.
    • Certificate Services: Allows your DC to serve digital certificates, signatures, and public key cryptography.
    • Lightweight Directory Services: Supports LDAP for cross platform domain services, like any Linux computers in your network.
    • Directory Federation Services: Provides SSO authentication for multiple applications in the same session, so users dont have to keep providing the same credentials.
    • Rights Management: Controls information rights and data access policies. For example, Rights Management determines if you can access a folder or send an email.

    What Services Does Ad Ds Provide

    Active Directory covers a range of services. AD Domain Services is the main service that encompasses these five services.

    Domain Services

    Domain Services stores centralized directory information and lets users and domains communicate. When a user attempts to connect to a device or resource on a network, this service provides login authentication, verifying the user’s login credentials and access permissions.

    Lightweight Directory Services

    AD LDS is similar to Domain Services, but it uses Lightweight Directory Access Protocol , which has fewer restrictions. AD LDS enables cross-platform capabilities that, for instance, let Linux-based computers function on the network.

    Active Directory Federation Services

    AD FS provides single sign-on authentication, enabling users to sign in once to access multiple applications in the same session.

    Rights Management

    This service controls data access policies and provides access rights management. For example, Rights Management determines which folders users can access.

    Certificate Services

    Certificate Services allows the domain controller to create and manage digital certificates, signatures and public key cryptography.
