DNS or Domain Name System is one of the central services that makes a server function. Without proper DNS set up nothing will work properly with OS X Server. DNS is basically the system that take our language of works and converts or translates those works into our computer systems language of numbers. So an IP address like 10.0.1.1 points to a machine with an address of www.example.com. So DNS is the system that manages that translation and makes sure all requests go to the right server so you get the results you were looking for. In this screencast I cover how to set up DNS in OS X Server. I cover how to start over in setting up your records. I also cover all of the records and what they mean and what services they are used for. I also talk about how to set up your DNS information on your domain name registrars site so everything gets to where it needs to be.
