manually created DNS records are scavenged

    Greetings,

    In our AD dynamic dnz zone, the servers A records were manually entered.

    To clean up the workstations dynamic dns records, scavenging was enabled for
    the zone.

    It seems the scavenging worked, however the servers A records now have the
    "delete record when stale ticked and are being removed, even after they are
    manually created, they still become timestamped.

    Question 1 - can this be reversed?
    Question 2 - how may this be avoided in the future?

    Please reply to the newsgroup
    Warm thank yous in advance

    Scavening is NOT your friend. There is a reason
    it is off by default. There are even better reasons
    for it being set to 2 1/2 WEEKS by default.

    Although manual records are not supposed to be
    scavenged anyway.

    Well IF (which I doubt) scavenging it causing it,
    then turn it off.

    Thanks Herb,

    Scavenging was turned off.

    Can anyone else on this newsgroup offer a resolution or intelligent advice
    to this?

    Please refrain from one-liners and opinions since my time is extremely
    valuable.

    Thanks again.

    You are right, time is valuable for many of us.

    That said, and I don't want to waste your time or mine, it depends on how
    you've configured scavenging,. if are getting any Event log errors, if the
    server record you created is already a DNS server, and how you've created
    the static entry, whether to allow it to be scanvenged or not.

    I took the time to look up some links for you. If you have some time to read
    them, they may help you by explaining exactly how it works, how to configure
    scavenging and how to create a record so as to not get scavenged. Disregard
    the OS versions listed. It's pretty much the same for both.

    I'd really like to know the purpose of scavenging. I thought it was to
    delete stale records. Would one want this feature turned on, and happening
    very frequently?

    It is but such records are not nearly as big a problem
    as much people presume and PREMATURE scavenging
    can wreak havoc on your domain.

    Leave it set to the defaults (2 1/2 weeks) or longer,
    especially if you have a WAN.

    ....unless you have thousands of stale records even then
    and you know PRECISELY how AD uses DNS and
    your WANS are extremely fault tolerant. (Or you
    have no WANS.)

    That's the purpose. Whether you want or need it depends on your environment.
    Don't set it less than 7 days. Read those articles for specific info on how
    it works, why would you want it, and how you would want to optimize it.
