Join Machines to Active Directory Domain - IT Guide

Joining Computers to an Active Directory Domain

Having successfully installed Active Directory on your network, the next crucial step is integrating your machines into the domain. Without this, your Domain Controller lacks practical function.

This guide details the process of adding computers to an Active Directory domain. It’s part of a larger series focused on fundamental IT administration concepts, and may not be universally applicable.

Key Considerations Before Joining

The process of adding a computer to an Active Directory domain is relatively straightforward. However, adhering to these three points will ensure a smooth and successful integration.

• Prior to joining, rename the computer to a descriptive and easily identifiable name.
• Verify that your DNS settings are correctly configured to point to the appropriate DNS server for your domain.
• Ensure you possess credentials for a domain account that is a member of the Domain Admins security group.

Proper preparation in these areas will prevent common issues during the domain joining process.

Remember, a well-managed domain relies on consistent naming conventions and accurate network configurations.

Adding a Computer to a Domain

Begin by accessing the Computer settings and selecting the System Properties option.

Next, on the left-hand side, click the link labeled "Advanced system settings."

Upon opening the advanced system settings window, navigate to the "Computer Name" tab.

Select the "Change" button; this allows you to assign a more user-friendly name to your computer.

Switch the radio button located in the lower section of the window. Change the setting from "Workgroup" to "Domain." This action will enable the text box below.

Enter the name of your domain into the now-available text box. In this example, it is "howtogeek.local," but your domain name will reflect the one established during Active Directory setup.

After pressing Enter or clicking "OK," a prompt will appear requesting the username and password of a Domain Admin account.

Providing valid credentials will result in a successful welcome message to the domain.

Steps Summarized

• Access System Properties.
• Open Advanced System Settings.
• Go to the Computer Name tab.

Successfully completing these steps integrates the computer into the Active Directory domain.
