Is there a distinction between statically added RRs and manually added RRs ?
In the following quote from Microsoft site, it saids that you can enable scavenging for RR addded statically, and then in the notes, they added that the time-stamp for manually added RRs is always 0, excluding it from the scavenging process.
QUOTE
To reset scavenging and aging properties for a specified resource record
Open DNS.
In the console tree, click the applicable zone.
Where?
DNS
applicable DNS server
Forward Lookup Zones (or Reverse Lookup Zones)
applicable zone
In the details pane, double-click the resource record for which you want to reset scavenging and aging properties.
The properties for the selected resource record appears.
Depending on the how the resource record was originally added to the zone, do the following as appropriate to reset the Delete this record when it becomes stale check box:
If the record was added dynamically using the DNS dynamic update protocol, you can clear the check box to prevent its aging or potential removal during the scavenging process.
If you added the record statically, you can select the check box to permit its aging or potential removal during the scavenging process.
Notes
To open DNS, click Start, point to Programs, point to Administrative Tools, and then click DNS.
This procedure is only necessary for resource records that are dynamically registered. For records that you manually add to a zone, a time stamp value of zero always applies to the record, excluding it from the scavenging process.

I tried to check the box "delete this record when it becomes stale", and click "apply", the manually added RR does gets a time-stamp, but after perfoming dnscmd /ageallrecords, I don't see a time stamp on the record. Does dnscmd /ageAllRecords apply to manually added RRs ?
