Hello, I am new here and I'd like to get your help on some points. I have began a book called MCTS certification preparation for Active Directory infrastructure with Windows 2008 et Windows 2008 R2. In fact, this is a translation because it is a french book. It's telling about DNS and Master DNS which is a concept I do not undestand. I can get Primary and Secondary servers but not Master DNS, is anybody knows ? Could you help me on that, please ?
