Updating the root servers on the DNS servers, by default when DNS server is installed a list of root servers comes with the server. In this Tutorial we are going to update the list on a server and use that server as basis to update other servers.
The first step is to check the root hints on the following site: ftp://ftp.rs.internic.net/domain/db.cache
After that we can open the DNS Manager, and then click on Root Hints.
Update the entries based on the file that you accessed at the beginning of this Tutorial.
After completing the first DNS Server, the administrator can go to the remaining servers, and use the option Copy from Server and specify the IP or name of the up-to-date server and that will automatically configure the root hints on that given server.
