Win 2012 R2 domain
3 X DNS servers all AD integrated
500 internal PCs across 8 scopes
Occasionally a guest may plug a laptop into one of the scopes above and need IP etc
1 scope of wireless clients which may have 1000 clients
Can u please advise on these DNS Qs
1. Lots of sites advise Lease period = refresh + no refresh, so that's easy I'll have 6, 3 and 3...OK? Not too worried about IPs running out.
2. Given numbers above what should scavenging period be? Not too worried about server processing this, scopes are small.
3. Should this scavenging period be set the same on the scope and server?
4. Given the setup above what update setting should I use, secure only, or secure and Unknown?
