10 - Windows Server 2022 Install and Configure DHCP Server (Video Tutorial in Khmer)

Hello my friend! Today I show you step-by-step how to Install and Configure DHCP Server in Windows Server 2022! DHCP server automatically assign IP addresses, Subnet Mask, Default Gateway, and DNS settings to client computers on network, making network management super easy! Very easy to follow with video tutorial in Khmer! Let's get started!

Step 1: Set Static IP Address on Server

Before installing DHCP Server role, your server MUST have Static IP address configured on network adapter!

1. Press Win + R, type ncpa.cpl and press Enter to open Network Connections.
2. Right-click your network adapter > Properties > select IPv4 > click Properties.
3. Set static IP (example: IP 192.168.1.10, Subnet 255.255.255.0, Gateway 192.168.1.1, Preferred DNS 192.168.1.10).

💡 Tip: Never use dynamic (DHCP) IP on DHCP server itself! Server must always use fixed static IP address so clients can locate server reliably!

Step 2: Install DHCP Server Role

Now we install DHCP role using Server Manager:

1. Open Server Manager > click Add roles and features.
2. Click Next on Before You Begin screen.
3. Select Role-based or feature-based installation > click Next.
4. Select your local server from server pool > click Next.
5. Check box DHCP Server. Click Add Features when popup show up > click Next.
6. Click Next through Features and DHCP Server overview screen.
7. Check Restart the destination server automatically if required > click Install button!

💡 Tip: DHCP role installation is very fast and typically does not require rebooting your Windows Server!

Step 3: Complete DHCP Post-Install Configuration & Authorization

After installation finish, we must authorize DHCP server in Active Directory!

1. In Server Manager top menu bar, click Notification Flag (⚠️) > click Complete DHCP configuration.
2. Click Next on Description screen.
3. Choose authorization credentials:
   • Select Use the following user's credentials (make sure account is Domain Admin like REAN\Administrator).
4. Click Commit button, then click Close.

⚠️ Warning: If server joined to Active Directory domain and you skip Authorization step, DHCP server will NOT give IP addresses to client PCs! Unauthorized DHCP server is blocked by Active Directory domain security!

Step 4: Create New DHCP Scope (IP Pool)

Now let's create DHCP Scope to define range of IP addresses for client computers!

1. In Server Manager, click Tools > select DHCP.
2. Expand your server name > right-click IPv4 > select New Scope....
3. Type Scope Name (example: Office Network Scope) > click Next.
4. Set IP Address Range:
   • Start IP address: 192.168.1.100
   • End IP address: 192.168.1.200
   • Subnet mask: 255.255.255.0 (Length: 24)
5. Add Exclusions (optional): Leave blank or add IPs you want reserved (like printer IPs) > click Next.
6. Lease Duration: Default is 8 days (click Next).
7. Select Yes, I want to configure these options now > click Next.
8. Configure Scope Options:
   • Router (Default Gateway): Add 192.168.1.1 > click Add > click Next.
   • DNS Domain Name and Server: Type Domain Name (rean.local) & IP 192.168.1.10 > click Add > click Next.
   • WINS Servers: Skip or click Next.
9. Select Yes, I want to activate this scope now > click Finish!

💡 Tip: Keep Start IP range separated from static server IPs (example: server IPs 192.168.1.1 - 192.168.1.50, DHCP client IPs 192.168.1.100 - 192.168.1.200) to avoid IP conflict on network!

Step 5: Verify DHCP Client IP Auto-Assignment

Now test on client PC (Windows 10 / Windows 11) connected to same network switch:

1. On client PC, open Command Prompt (cmd).
2. Release old IP address and request new IP from DHCP server:

# Release current IP
ipconfig /release

# Request new IP from DHCP Server
ipconfig /renew

# Display full IP, Gateway, DNS info
ipconfig /all

3. Check output! Client PC should get IP address inside your range (192.168.1.100) and DNS server IP (192.168.1.10)!

💡 Tip: You can view all connected client PCs inside Server Manager > DHCP console > expand IPv4 > Scope > Address Leases!
