Study Notes
Active Directory Overview
- Active Directory (AD) is a directory service developed by Microsoft for managing network resources, users, and devices.
- Provides a centralized platform, simplifying administration and security.
Key Components
- Domain: Logical grouping of network resources sharing a common security policy.
- Forest: Collection of domains with shared directory schema and global catalog for communication.
- Site: Geographical location defining boundaries for replication and communication between domain controllers.
User Accounts and Groups
- User Accounts: Represent individual users on the network providing access to resources and managing permissions.
- Groups: Collections of user accounts sharing common access rights and permissions simplifying administration.
- Nested Groups: Allow for complex group structures enabling hierarchical permission management.
Computer Accounts
- Member Servers: Servers joining a domain, managed by AD for centralized administration and security.
- Domain Controllers: Specialized servers hosting a copy of the AD database, managing network authentication and authorization.
- Workstations: Client computers joining a domain subject to domain policies and security settings.
Organizational Units (OUs)
- Hierarchical organization enabling administrators to logically group objects based on department, location, or function.
- Delegated Administration: Controlled delegation of administrative tasks to specific users or groups within OUs.
- Targeted Policies: Application of specific Group Policy settings to individual OUs, tailoring security and configuration to specific needs.
Group Policy
- Security Settings: Control user access rights, password complexity, and network security.
- Software Settings: Manage software installations, updates, and configurations.
- Network Settings: Configure network access, VPN connections, and internet settings.
- User Preferences: Customize user desktops, start menus, and preferences.
Domain Controllers
- Authentication: Domain controllers verify user and computer identities and provide access to network resources.
- Authorization: Domain controllers enforce access controls and permissions based on user and group memberships.
- Database Management: Domain controllers store and manage the AD database, providing a central repository of information.
- Replication: Domain controllers replicate changes to the AD database ensuring data consistency across the network.
Replication and Redundancy
- Changes: When changes are made to AD, they are replicated to other domain controllers.
- Consistency: Replication ensures all domain controllers have a consistent copy of the AD database.
- High Availability: Redundancy ensures network functionality even if domain controllers fail.
Backup and Restore
- Regular Backups: Regularly backing up the AD database is crucial for disaster recovery.
- Backup Strategies: Implement comprehensive backup strategies including full, incremental, and differential backups.
- Restore Procedures: Establish clear restore procedures for timely recovery in case of data loss.
Troubleshooting Active Directory
- Identify the Issue: Gather information about the problem, such as error messages, event logs, and user reports.
- Analyze the Problem: Examine logs, check user and computer accounts, and review Group Policy settings to determine the cause of the issue.
- Apply Solutions: Implement appropriate solutions, such as resetting passwords, and troubleshooting network connectivity issues.
