I am adding a second domain controller to a site for the purpose of replication for disaster recovery purposes. I have several questions that my research has not provided clear answers. This is a relatively simple network with AD primarily housing user names, passwords, and network shared resources such as printers. These are the only domain controllers on the network, both running Windows Server 2003 in the same site. Should I just install AD on this second controller and let it replicate automatically with the first controller or would it be a better idea from a control point of view to generate the replicated data from a media backup? Don't consider network throughput to be a concern as I am sure the replication would be uneventful with respect to network overhead and bandwidth, and I will do this during closed hours. Also how should I manage DNS on the second controller from the standpoint of disaster recovery in the event of a problem with the first controller and also from the standpoint of the the initial replication? Should I make the second domain controller a global catalog server or just leave that designation to the first controller only? Thanks for any input!!!
