I'm trying to clarify the relationship between SOA records and AD based DNS since we are switching towards an all AD integrated DNS scenario in our environment.
We have 2 DCs running Win 2008. The goal is to ensure DNS redundancy and give domain client machines the ability to update their records directly on whatever server is available if one goes down...or both servers if they are both available.
Should both DCs host these primary integrated zones? Or should one host a primary integrated and the other a secondary (and hence integrated) version of it?
How does this work with SOA records? If you have two primary integrated zones does that not imply the possibility of two SOA records since both zones are directly updateable? Can you have more than one SOA record per domain?
Or can you only have one SOA record corresponding to the DC that hosted the integrated primary zone first, independent of whether the other DC has a primary or secondary zone of the same domain?
What is the best setup for such situation? What would you do?
Thank you in advance.
