DNS "Delete this record when it becomes stale"

    I have 4 DCs in 2 sites. 1 forward lookup zone, corp.company.com. My DCs
    and my mail servers keep getting the "Delete this record when it becomes
    stale" box checked. I uncheck it, and look at it later and it is checked
    again. I have tried deleting and recreating the record, when I create the
    record the box in unchecked, later it is checked again.

    How do I make it so that these records are not aged?

    Replication is to all DNS servers in the Active Directory Forrest.
    Dynamic updates is set to Non-secure and Secure.

    TIA

    check one of those DCs network config (TCP/IP properties) - is it set to
    'register this connection in DNS?'

    I think the trick is to disable the DHCP client service.

    Do not disable the DHCP Client service, it is required for DNS
    registrations. Why would you want the DCs to not be able to keep their DNS
    records up to date?
    Unless you have set the scavenging time to way to short of a time, there
    would be no reason to worry about the checkbox.

    You're seeing default behavior when it comes to static (manually created)
    entries or machines with with static IPs registering. What record(s) are you
    deleting and re-creating? DCs will auto register their host and SRV records.
    That is the basis of how and why AD works. If you attempt to alter this
    behavior, there are certain rules concerning what needs to be registered in
    DNS.

    Can you elaborate on this? Also, the DHCP client service does two things:
    DNS registration, and name resolution, whether the machine has a static IP
    or DHCP config, despite it's name. That's a crucial service an something you
    really don't want to disable, as Kevin mentioned, on any machine, especially
    a DC.

    I have several Servers that as soon as I turn on scavenging their A record
    disappears. I have tried unchecking the "Delete this record when it becomes
    stale" but that box keeps getting rechecked and the records are being
    scavenged.

    My DHCP server is out of my control and there is NOTHING that I can do with
    it. the DHCP lease time is 4 hours. Scavenging is set to No-Refresh 2 hours
    and the Refresh is set to 2 hours.

    The scavenging period is set to 8 hours.

    I need to have scavenging working, but I cant have server A records
    disappearing every day. Suggestions ?

    Minimum scavenging time, if I remember, is one day. However this conflicts
    with the DHCP lease of 4 hours. This will cause issues. Read this article
