Configuring the Web server

By default, the port used by the Web server is 8080, logging is enabled, and 7 days of logs are saved. A new log file is created each day and the logs are stored in the server logging directory in the WebLogs folder. You can change the port used by the Web server and the logging settings. When you click OK, the port is checked to see if it is in use. For example, if the server is running a Web server such as IIS, and you enter port 80, you will receive an error because IIS is already using port 80.

Diagnostic Console

The Diagnostic Console is a powerful diagnostic and resolution tool. Its unique user interface provides a real-time representation of the data flow in your forest, allowing you to detect, diagnose, and resolve Active Directory problems.

The Diagnostic Console offers expert help that explains each process and counter on a domain controller, and what a raised alarm means. The help system offers suggestions on how to resolve the alarm, common solutions, and next steps.

Graphical flows illustrate the rate at which data is moving between domain controller components. Components display the value of key statistics and metrics. The power of the Diagnostic Console lies in its ability to provide visual and audible warnings if performance metrics exceed acceptable thresholds. Components change color to show you the source of the problem.

A range of reports and graphs provide you with detailed information about a domain controller. This information can be viewed on the screen, or printed.

Opening the Diagnostic Console

The Diagnostic Console opens in a separate window. You can move it aside while you work in Active Administrator.

IMPORTANT: To use the Diagnostic Console, you must set a default printer. Windows Server® 2016 and Windows Server 2019 set the default printer automatically, but you should verify that it is set.
Select Active Directory Health | Analyze, select a domain controller, and click Diagnose.

Using components

The components on the Diagnostic Console home page correspond to the elements of the domain controller that is being diagnosed. Components change color to alert you to specific performance problems.

To see an explanation of the performance, hold the cursor over the component to open a tool tip. To see a definition, click the component to open a help box. From the help box, you can open the associated drilldown to view the associated statistics in table and graph format. See Using drilldowns.

Each component has a right-click shortcut menu from where you can open a help box, show the history in a graph, view details (opens the associated drilldown), restore default settings, view metrics, and view properties.

The home page for the selected domain controller displays the following types of components:
