In a Windows Server 2016 environment, DNS plays a key role in ensuring the smooth functioning of various network services. This article aims to help you know how to backup and restore DNS in Windows Server 2016 in case of any system failure.
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.
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:

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.
