I have about a hundred DNS zones that I need to convert from being not AD integrated to be AD integrated. I want to do this with minimal downtime. So far, my process is:
- Change DNS zone on one DNS server (also domain controller) to be AD integrated
- Delete the DNS zone from the DNS server where it is the secondary zone (also a domain controller)
- Wait a period of minutes for the zone to be replicated to the second server at this site.
- We actually have two sites involved with this, so we have to wait even longer for the replication to the second site
Is there some way to speed up DNS replication between: servers on the same site, and servers at different sites? We have Server 2008 R2 DNS/DCs, and at the 2003 domain functional level.
