Here is the English script of our YouTube video - Active Directory part 1. We also have a German video.
So before we come to some of recently changes in Active Directory, we want to make a short review of the existing Active Directory replication procedure.
There were two design decisions, on which Active Directory was built.
As a consequence of those two design decisions we get most of the active directory structure we got today.
The first design decision was to have a Multi-master architecture.
Why? Because of the problems we had with the single master approach with the old primary domain controller or PDC. There were high availability issues.
Did that design goal work?
