DNS timestamp replication (again), and Scavenge vs Enable Automatic scavenging

-

i've read posts on "dns record timestamp replication" can find on forum, , i'm still concerned enabling scavenging on multi-server dns infrastructure, after it's been off forever.

if have 3 dns servers, , different clients update dns on different dns servers, "last refresh" timestamp can different depending on dns server at. think that verifying timestamp replication @ top of any pre-enabling-scavenging to-do list.

but can't be, because *timestamps don't replicate unless scavenging turned on.*

so assumed solution turn on scavenging on 1 dns server, enable other dns servers replicate current timestamps *to* it, don't see timestamps changing on server2 enabled scavenging. know dns replicating ok because if create new record on server1 appears on server2. existing timestamps on server2 not updating newer timestamps of server1, after enabled scavenging on server2.

if timestamps don't change on server2, going scavenged, , deleted server1 even if timestamp on server1 is 5 minutes before scavenging starts. right?

second issue:

in 2008 r2 dns console, i right click server name, "set aging/scavenging zones," check box says "scavenge stale resource records."

and/or

in 2008 r2 dns console, right click server name, choose properties, advanced tab, , check box says "enable automatic scavenging of stale records."

what difference between these two?
need both boxes checked before scavenged?
how work together?
what does checking first 1 do?
checking the second 1 do?

oclist /xml or /?

oclist have qualifiers? can behaviour changed, example output xml?   given previous comments andrew m , comments in forums , blogs think answer no, it’s simple app calling underlying api, thought i'd ask can't seem find anything.   why asking question? i'd @ least 2 things oclist (apart nicer looking output [which i'm not going get], dependances listed [dicussed in forum , ruled out], , refrushing add ad componets , telling use dcpromo [which in banner know]): - whether installing component cuase / require reboot (currently believe qwave , printing services require reboot)   - xml output, can't justify team looking see if can commality with full server   fwiw :j   hi,   oclist not have qualifiers or ways change output. when iis came in late, make oclist output longer, unfortunately late make significant changes.   i'll take feedback , add our list next version.   thanks,   andrew   ...
