07 - Windows Server 2022 Join Domain (Video Tutorial in Khmer)

Hello my friend! Today I show you step-by-step how to Join Windows Client PC or Server to Active Directory Domain in Windows Server 2022! Once joined to domain, users can login with domain accounts and IT admins can control security policies centrally! Very easy to follow with video tutorial in Khmer! Let's get started!

Step 1: Set Preferred DNS to Domain Controller IP!

Before joining domain, your client PC or server MUST point Preferred DNS server to your Domain Controller IP address!

1. Open Network Connections (ncpa.cpl).
2. Right-click network adapter > Properties > select IPv4 > click Properties.
3. Set Preferred DNS server: 192.168.1.10 (Enter your Domain Controller IP!).

💡 Tip: This is #1 common mistake! If Preferred DNS points to public internet (like 8.8.8.8), computer CANNOT find domain name (rean.local) and join domain will FAIL!

Step 2: Test Network Connection to Domain Controller

Open Command Prompt (cmd) and test pinging your domain controller:

# Ping Domain Controller IP
ping 192.168.1.10

# Ping Domain Name
ping rean.local

💡 Tip: If ping rean.local resolves IP 192.168.1.10 correctly, your DNS setup is 100% ready for domain join!

Step 3: Join Computer to Active Directory Domain

1. Press Win + R, type sysdm.cpl (System Properties), and press Enter.
2. Click Computer Name tab > click Change... button.
3. Under Member of, select Domain option radio button.

   • Username: REAN\Administrator (or user with domain join permission).
   • Password: YourDomainPassword
6. Click OK! You will see message: Welcome to the rean.local domain!

💡 Tip: Make sure computer name is unique (like PC-IT-01 or SRV-WEB-02) before joining domain! Do not leave default generic name like DESKTOP-X1Y2Z3!

Step 4: Restart & Log In with Domain Account

1. Click OK > click Restart Now to finish joining domain.
2. After reboot, click Other user on Windows login screen.
3. Log in using domain user format: username@domain.local or DOMAIN\username (example: sok.dara@rean.local or REAN\sok.dara).

Congratulations! Your computer is now joined to Active Directory domain!
