• Navigate to the "Devices" tab and click "Add Device".
• Enter the IP address or hostname of the Active Directory server you want to monitor.
• Provide authentication credentials (e.g., SNMP, WMI) for accessing the Active Directory server.
• PRTG will automatically discover available sensors for Active Directory monitoring.

Configuring Active Directory Monitoring Sensors:

• Select the appropriate Active Directory monitoring sensor (e.g., WMI Service Sensor, LDAP Sensor).
• Configure sensor settings such as monitoring intervals, LDAP query parameters, and authentication details.
• Define specific Active Directory services to monitor, such as domain controller availability, LDAP service status, and replication health.

Dashboard Customization:

• Customize the dashboard to display Active Directory service and authentication metrics.
• Add widgets for real-time and historical data visualization.
• Arrange the layout for easy monitoring of Active Directory services and user authentication.

Setting Up Alerts:

• Configure alerts for Active Directory service failures or authentication issues.
• Define thresholds for acceptable service availability, replication status, and user authentication failures.
• Choose notification methods (email, SMS) for alerts to ensure timely awareness of Active Directory issues.

Historical Data Analysis:

• Analyze historical data to identify trends in Active Directory service availability and user authentication.
• Generate reports to gain insights into domain controller uptime, LDAP query performance, and authentication trends over time.
• Compare data across different Active Directory servers or periods for performance evaluation and troubleshooting.

Security Incident Response:

• Use authentication data to respond to security incidents promptly.
• Investigate authentication failures to determine the root cause and potential security threats.
• Take appropriate actions to mitigate security risks and prevent unauthorized access to Active Directory resources.

Integration and Automation:

• Integrate PRTG with other security tools for enhanced functionality.
• Automate monitoring tasks such as alert acknowledgments and incident response actions.
• Leverage third-party integrations for advanced analysis and reporting of Active Directory service availability and user authentication.

Maintenance and Updates:

• Keep PRTG updated to access the latest features and security patches.
• Monitor PRTG health for optimal performance.
• Perform routine maintenance tasks like database cleanup and sensor optimization.

By following these steps, you can effectively monitor Active Directory services and user authentication using PRTG Network Monitor, ensuring that your Active Directory infrastructure remains available, secure, and performing optimally to support your organization's IT operations.
