Undestanding DNS 1

[jonnyknowsbest]

We have 4 servers in our Active Directory Domain. When i look at the DNS properties of each of the 4 servers, they all have SOA records that point to themselves. Is this correct or should they all use the same SOA record?

If they are Active Directory Integrated Zones, the answer is yes. It does look odd, but each AD Integrated Zone is Authoritative over the Zone. Each server has a writable copy of the Zone file. AD keeps track of what changes in each Zone, and replicates those changed to the other DNS servers.
