Hi,
I have 5 DC with DNS in different site connect with WAN LInk, main site have 2 DC and rest of the 3 site as additional DC, infobox serve as DHCP with lease time 9 hours for DHCP client.
All DC server running windows 208 R2 SP1 and Running DNS Active Directory Integrated Zone with Dynamic update.
My plan is enable it on 2 main DC in main site and the interval is default 7 days. As i read some article suggest it must equal or not less than DHCP lease time?
I have forward and reserve lookup zone configure under domain name XXXX.local
Any advice on enable DNS aging and scavenging? Do i need to enable it on all the DC in all site under XXXX.local or i just only enable it on 2 DC in main site only?
