Hi all,
We use Exchange 2010 SP2. According to this link, when planning for DAG, client-facing DNS records should have a TTL of 5 minutes. Currently, our AD DNS zone has the following intervals set:
Refresh Interval: 15min
Retry Interval: 10min
Expires after: 1day
Minimum TTL: 2hours
TTL for this Record: 2hours
So, just to be clear, I should set the last two both to 5 min? What about the other intervals? What length of time are others using for those?
