What is DNS
DNS, the acronym for Domain Name System, is a hierarchical and distributed naming system that acts as a phonebook for the internet. It translates human-readable domain names, like www.example.com, into machine-readable IP addresses, such as 192.168.1.1. This translation process allows you to access websites, send emails, and perform various network activities without having to remember complex numerical IP addresses.
The key role and significance of DNS on Windows Server 2016
DNS plays a key role in the functioning of a Windows Server 2016 environment, and its significance lies in its ability to provide seamless and efficient network communication. The primary roles and significance of DNS on Windows Server 2016 are as follows:
- Domain Name Resolution: DNS acts as a reliable phonebook for the internet, translating human-readable domain names, like www.example.com, into machine-readable IP addresses, such as 192.168.1.1.
- Load Balancing: In scenarios where multiple servers host the same service, DNS can be used for load balancing. By distributing requests across multiple servers with the same hostname, DNS helps optimize resource utilization and improve overall system performance.
- Fault Tolerance: DNS can be configured with redundancy to provide fault tolerance. By setting up multiple DNS servers or changing DNS servers, if one server fails, the other servers can continue to handle DNS queries, ensuring continuous domain name resolution.
- Active Directory Integration: In a Windows Server environment, DNS and Active Directory are closely integrated. DNS is crucial for locating and authenticating Active Directory domain controllers, allowing efficient user authentication and management within the domain.
- Zone Management: Windows Server 2016 DNS supports the creation of DNS zones, which are authoritative domains for which the DNS server is responsible. You can manage and configure these zones to control name resolution and resource mapping within their domain.
How to backup and restore DNS Windows Server 2016
Regularly backup DNS zone is critical to safeguarding against potential data loss or system failures. Here is a step-by-step guide on how to take DNS backup in windows 2016 server and restore DNS from backup:
Backup DNS Windows Server 2016
For this kind of DNS operations, Microsoft created the DNSServer and DNSClient PowerShell modules, notably the Export-DnsServerZone cmdlet. The following example demonstrates the simple syntax for backup DNS PowerShell:
Export-DNSServerZone "zone name" "zone file name"
dnscmd /zoneexport "your zone name" "zone file name"
dnscmd /zoneadd "yourzone.com" /primary /file yourzone.com.dns /load
Restore DNS Windows Server 2016
1. Instead of pasting the zone file into the backup folder, place it in the root of the c:\\windows\\system32\\dns folder.
2. Click Next in the DNS dialogue box to create a new zone from the DNS management console.
3. To save a restored zone in AD during the creation process, you can select or uncheck the store in Active Directory checkbox.
4. Name the DNS zone file exactly as the DNS zone you have backed up.
Note: Pay attention to the warning that the file must be copied to the folder %systemroot\\system32\\dns.
5. The Dynamic Update option will be set to Do not allow dynamic updates by default when importing. This implies that your clients won't be able to automatically update DNS. It is possible to configure it to accept both secure and insecure dynamic updates, but doing so poses a security risk.
Note: The allow only secure dynamic updates has been disabled. Active Directory only makes this option available for integrated zones.
6. Finish the New Zone Wizard. As you can see, the new zone is created and mounted in the DNS server.
