19 - Windows Server 2012 How to Configure DNS Server (Video in Khmer)

Hello my friend! Today I show you step-by-step how to Configure DNS Server on Windows Server 2012 R2 inside VMware! DNS (Domain Name System) translates easy domain names (like www.mycompany.local) into IP addresses (like 192.168.1.100) so client computers can connect to server resources easily without remembering IP numbers! Follow steps below with video tutorial in Khmer! Let's get started!

💡 Tip: Always configure both Forward Lookup Zone (translates Name to IP) and Reverse Lookup Zone (translates IP to Name) for complete DNS resolution!

Step 1: Open DNS Manager Console

1. Open Server Manager > click Tools menu at top right > select DNS (dnsmgmt.msc).
2. Expand your Server Name in left panel (example: DC01).

Step 2: Create Forward Lookup Zone (Name to IP)

1. Right-click Forward Lookup Zones folder > select New Zone....
2. Click Next on wizard > select Primary zone > check Store the zone in Active Directory > click Next.
3. Select To all DNS servers running on domain controllers in this domain > click Next.
4. Enter Zone name (example: mycompany.local) > click Next.
5. Select Allow only secure dynamic updates > click Next > click Finish.

💡 Tip: Forward Lookup Zone is used when user types domain name like web.mycompany.local in web browser to find server IP address!

Step 3: Create Host (A) Record in Forward Zone

1. Right-click your new zone (mycompany.local) > select New Host (A or AAAA)....
2. Type Name (example: web or www).
3. Type target IP address (example: 192.168.1.100).
4. Check box Create associated pointer (PTR) record > click Add Host > click OK > click Done.

💡 Tip: Checking "Create associated pointer (PTR) record" automatically creates matching reverse record inside Reverse Lookup Zone!

Step 4: Create Reverse Lookup Zone & Test with nslookup

1. Right-click Reverse Lookup Zones > select New Zone... > select Primary zone > click Next.
2. Select IPv4 Reverse Lookup Zone > enter Network ID (example: 192.168.1) > click Next > click Finish.
3. Open Command Prompt (cmd) on client computer > type nslookup web.mycompany.local > press Enter.
4. Output shows server IP address and domain name resolving correctly!

💡 Tip: If nslookup shows old IP or error, run command ipconfig /flushdns in Command Prompt to clear client DNS resolver cache!
