I was curious about the static record thing with AgeAllRecords. I just tried
it and it aged my dynamic records but not the static one I had (i.e. the
checkbox to delete was not checked on the static record, but it was on the
dynamic one). This is w2k3 sp1. I’m not 100% confident in my results as I
set scavenging, turned it off, created a test static record, turned it back
on, ran ageallrecords, and then checked it… all within about 10 minutes.

Thanks for the input.  Luckily for us we do not have any static records, at
least I have not created any but I will check with the other Admins to be
sure.

 

I thought AGEALLRECORDS for bring the prior records into the fold and then
they would be scavenged out in the next cycle.  Guess we will give it a try
and let everyone know how it turned out.

You are correct.  

 

Due to the fact that aging/scavenging was not enabled the records which were
dynamically registered were not stamped with a date/time.  Therefore the
aging/scavenging process ignores them upon starting it’s scavenging process.

 

You can use the AgeAllRecords which will do just that.  Age ALL your
records.  You have to be careful though.  I haven’t proven this but I
believe that it will also turn your static records into dynamic record (time
stamp them).  Then when you run AgeAllRecords…well guess what?...

 

To prevent this, Once you ageallrecords you will have to go back into the
DNS console and ensure that static/manually created records you need are not
set to Delete this record when it becomes stale by unchecking the box in the
record properties.  You might have to enable the advanced view (View
àAdvanced) to view this as well as the timestamp of the record.

 

Once you’ve completed this you can then right click on the DNS server name
in the DNS console and select Scavenge Stale Resource Records or via command
prompt: dnscmd <servername> /StartScavenging

 

Note: In order to successfully configure Scavenging and Aging you will need
to enable it both on the zone and the DNS server. Which I’m sure you have
already…but just in case…

 

Right click on server nameàPropertiesàAdvanced tabàcheck the Enable
automatic scavenging of stale records or you can enable it for all zones by
right clicking on the server name and selecting Set Aging/Scavenging for all
Zones…àcheck the box Scavenge stale resource recordsàOKàcheck the box to
apply these settings to the existing Active Directory-integrated zones (if
AD integrated)àOK then go to the zone and right clickàPropertiesàGeneral
tabàAging button and check the Scavenge stale resource recordsàOK

 

Hope this will help…please chime in…

Subject: [ActiveDir] DNS scavenging question

 

I have a rather off the wall DNS scavenging question.

 

I have a bunch of DNS records that are stale and need to be scavenged

out of the zone.  Following the O'REILLY book: DNS on Windows Server

2003 I have configured aging and scavenging.  (Don't ask why this

wasn't done when the zone was first setup, that is another story)

 

Now I know: If scavenging is disabled on a standard zone and you enable

scavenging, the server does not scavenge records that existed before

you enabled scavenging. The server does not scavenge those records even

if you convert the zone to an Active Directoryintegrated zone first. 

 

To enable scavenging of such records, use the AgeAllRecords in

Dnscmd.exe.  I know this must be done in order to configure existing

records to a scavengable state.

 

Is there a way to immediately force a scavenge cycle that will remove

all stale records?  I would not to have to wait unitl the "no-refresh"

and "refresh" intervals expire.
