Keep in mind that you CAN enable scavenging on static records. The facility is
in dnscmd. So, please don't assume that your static records are safe from
scavenging just because you don't see a timestamp.

Correct. When a server runs scavenging it'll determine which of the primary
zones it hosts has it enabled and then which records in those zones are "stale"
based on the no-refresh and refresh intervals. Also keep in mind scavenging
only applies to records that have timestamps (which are typically dynamically
created.) And make sure none of the zones have too short of no-refresh/refresh
intervals where valid records could be removed. You can do due diligence by
ensuring you have current and valid backups. You may want to also check out
KB838851 just to be sure it doesn't apply to your environment.

OK that explains my problems then. When I enable it at the server
level, it won't actually do anything to the zones that aren't enabled,
correct? I mean, is it a two step process, you enable the server, and
then enable the zones you actually want to scavenge one at a time? I
just don't want anything to disappear out of DNS suddenly when I enable
the server level, that ends up being a CLM (career limiting move).

Unless you enable it on a server (or manually initiate it against a
server) nothing's actually being scavenged. The settings on the zone
only allow the timestamps to replicate and defines what records would be
deleted assuming scavenging is run. So until a DNS server that hosts a
primary copy of the zone performs the scavenging process you can
continue to watch those duplicates accumulate and your SMS admins
complain. :)

Subject: [ActiveDir] DNS Scavenging
We're in the middle of an SMS deployment and SMS is making us very aware
that DNS scavenging and WINS tombstoning doesn't appear to be happening
as much as it should. Looking through our DNS records for our domain,
there's like 2 and 3 machine names for one IP. Two of them were tossed
in the trash, one is still alive. We have scavenging set to 7 days on
the zones, but not enabled at the server level (that seems a bit
scarier). Shouldn't DNS scavenging work if enabled on the zone? We're
running Win2k3 on our DNS/DCs, some with sp1 some without.
Thanks in advance
