Common troubleshooting issues include account lockouts, DNS resolution failures, and trust relationship errors, which can be resolved through specific commands and built-in tools.

Add Active Directory Users and Computers

Active Directory Users and Computers (ADUC) is a Microsoft Management Console (MMC) snap-in that provides centralized management of domain resources including users, groups computers organizational units.

ADUC enables three core management functions:

Create user accounts with specific permissions access levels
Add computers to join the domain network
Organize resources into logical groups through organizational units (OUs)

The ADUC interface contains several key components:

Domain node – Shows the Active Directory domain structure
Built-in container – Houses default security groups system accounts
Computers container – Lists workstations servers joined to the domain
Users container – Stores user accounts contact objects
Domain Controllers OU – Contains domain controller computer accounts

Here’s a breakdown of the main resource types managed in ADUC:

Resource Type	Purpose	Common Tasks
Users	Employee accounts	Create modify delete accounts
Computers	Domain-joined devices	Add remove manage computers
Groups	Collections of users/computers	Assign permissions control access
OUs	Organizational containers	Delegate admin rights apply group policies

The ADUC console integrates with other Windows Server administration tools enabling tasks like:

Configuring Group Policy settings
Managing DNS records
Setting up file sharing permissions
Establishing trust relationships

The tool offers both a graphical interface command-line options through PowerShell for automating administrative tasks at scale.

Creating New User Accounts

Creating user accounts in Active Directory Users and Computers involves configuring essential properties and security settings to establish domain access for employees. The process follows a structured approach to ensure proper account setup and management.

Setting Up User Properties

Active Directory requires specific user properties for account creation:

Enter the user’s full name in the “”Name”” field to set the display name
Configure the “”User logon name”” with a unique identifier (e.g., jsmith)
Input contact details including email address, phone numbers and office location
Assign department and job title information for organizational tracking
Select the user’s manager from the directory for hierarchical structure
Define the home folder path for storing personal files
Set profile path settings for roaming profiles when applicable
Specify logon scripts to automate user environment configuration

Set password complexity requirements:
Minimum 12 characters
Uppercase and lowercase letters
Numbers and special characters
Configure password policies:
Password expiration period (e.g., 90 days)
Account lockout threshold (e.g., 3 failed attempts)
Password history count (e.g., remember last 24 passwords)
Define logon hours to restrict access times
Limit workstation access to specific computers
Set account expiration dates for temporary users
Enable smart card login requirements for enhanced security
Configure remote access permissions for VPN connections

Managing User Groups and OUs

User Groups and Organizational Units (OUs) streamline Active Directory administration by organizing users and applying group-based permissions. I’ll explain the creation of security groups and organization of users within OUs to establish an efficient management structure.

Best Practices for User Management

Active Directory user management requires standardized practices to maintain security and efficiency. These guidelines ensure consistent administration across the domain environment.

Naming Conventions

Active Directory naming conventions establish clear identification patterns for user accounts and objects. I implement these specific naming patterns:

Create usernames with firstname.lastname or firstinitiallastname format
Set computer names with location-department-number structure (e.g., NYC-IT-001)
Use descriptive group names with Department-Role-Access format (e.g., Sales-Team-ReadOnly)
Apply OU names that reflect business structure (e.g., Corporate-HR, Branch-Seattle)
Include position codes in display names (e.g., John Smith – SAL001)

Enable password complexity requirements (12+ characters with mixed case letters numbers symbols)
Set account lockout thresholds to 3 failed attempts
Configure password expiration cycles at 90-day intervals
Implement time-based access restrictions for contractor accounts
Apply principle of least privilege for user permissions
Enable multi-factor authentication for administrative accounts
Create separate accounts for administrative tasks
Monitor failed login attempts through security auditing
Document all permission changes in system logs

Security Setting	Recommended Value
Password Length	12+ characters
Account Lockout	3 attempts
Password Age	90 days
Admin MFA	Required
Session Timeout	15 minutes
