I am tasked with cleaning up and baselining our AD environment. I have 2003 r2, 208, 2008 r2 and 2012 r2 DCs that all have active directory integrated zones. They all have different aging/ scavenging settings. I want to make it to where the FSMO role holder does all the scavenging for the zones we have. What is the best way to do that? I know how to set scavenging and aging in the three different sections on DNS (Zone, DNS Properties, Set dns scavenging and aging button after right click).
What do I set on each DNS server?
