Scavenging + Timestamps + All things DNS

hi all. there multiple dns servers in environment (2003 x 3, 2012 x 4).

i configured dhcp manage dns. enabled dns scavenging.

another change. preferred/alternate dns values have been updated reference new 2012 dns servers.

domain controllers

site - preferred site b alternate site a

site b - preferred site alternate site b

servers:

site - preferred site alternate site b

site b - preferred site b alternate site a

recently dns records servers/esxi host etc have been deleted (scavenged) + other devices i unaware of sure of. on review note records timestamp = static whilst others have timestamp date has expired (and scavenged).

prior implementing scavenging not overly concerned i thought windows clients static ip's on adapters re-register in dns. not appear have happened.

i going uncheck setting 'delete record when becomes stale' on servers convert static entry.

question: approach or should run ipconfig /regeisterdns client maintains it's entry?

i ran ipconfig /registerdns on single server , timestamp did not update. have reviewed properties of record , although self has 'special' further review indicates no permission entries.

question: if manually re-add scavenged dns records on server replictae server b or server b replicate server , remove entry?

thanks,

phil.

hi phil,

>>question: approach or should run ipconfig /regeisterdns client maintains it's entry?

1.uncheck setting 'delete record when becomes stale'

2.check setting 'delete record when becomes stale' , static records should have timestamp of 0 indicating not scavenge. 

>>question: if manually re-add scavenged dns records on server replictae server b or server b replicate server , remove entry?

if set 1 primary zone , 1 secondary zone on network,it copy primary zone secondary zone zone transfer.
