Configuring the Secondary DNS Server. A DNS server is a computer server containing a directory of fully-qualified domain names FQDN and the corresponding public IP addresses for that domain. DNS stands for Domain Name System and is comparable to a phone directory for the internet.

A fully-qualified domain name is a hostname a domain name and a top-level domain TLD if the format of hostnamedomaintld. In computer networks a reverse DNS lookup or reverse DNS resolution rDNS is the querying technique of the Domain Name System DNS to determine the domain name associated with an IP address the reverse of the usual forward DNS lookup of an IP address from a domain name. A registry-based workaround can be used to help protect an affected Windows server and it can be implemented without requiring an administrator to restart the server.

With just a single command you can change the DNS server without having to click through all the Windows menus if for example the currently entered DNS server is not responding. The process of reverse resolving of an IP address uses PTR records. Luckily the secondary DNS server is much easier to configure.
