dns scavenging

[Graham Turner]

looking at the implementation of scavenging on the DNS server

looking to enable it on zones with the default values seems to the general
consencus of newsgroup

as i understand - manually entered entries are under NO circumstance
scavenged from the database ??

this then begs the question - how in fact does the DNS server differentiate
between administratively entered data and dynamically entered data

is it by ACL ???

DNS server (with scavenge activated) knows if a register
should be deleted when it has a time stamp value
associated.
To look at time stamp, in the DNS MMC select View-

Advanced.

With this view is activated you should see in the
properties of the record, the "Record time stamp".
If "delete this record when ." is not checked, de record
will not be deleted.

If you use dynamic DNS, you should leave this checkbox
checked, the DNS cliente and DHCP will manage their
updates automatically.

Yes, I have tried less -- and was UNHAPPY with the results.

The case can be made that except in extremely large and very
dynamic environments (laptops multi-national GM size companies
perhaps) there is little reason to worry about "fast scavenging."

Magic. <grin>

If you find out, I would be curious to know too. Obviously if it's stored
in memory, the Registry, or in AD, extra fields can be maintained, but what
about 'between boots' if it's stored in standard zone files?

I don't know -- probably the registry, since I have never caught DNS
adding 'extra' info or extra files to the DNS directory.
