Dynamic Update not working

    This is a Windows 2003 Domain and all servers are Windows 2003 with static IP
    addresses. They can successfully complete the initial registration with DNS
    but never update their time stamp so they are removed during scavenging. the
    servers have the correct primary dns suffix which matches the DNS domain.
    the correct DNS servers are listed in the IP configuration. the box to
    register this connection's addresses in DNS is checked. the aging and
    scavenging times are set to the defaults of 7 days for the No-refresh,
    Refresh and scavenging period. the servers can be forced to re-register with
    DNS with the ipconfig /registerdns command; but they do not update their
    timestamps on their own. the registry key to disabledynamic updates is not
    present. the servers all have the Write permission to their own record. our
    production domain does mcafee turned on with the block IRC checked, but our
    test domain does not have any anti-virus installed.

    is there anything else i can check or do?

    Is the DHCP Client service started? If it is not they will not update
    records.

  3. In addition to Chris' suggestion, are there any event log errors?

    How many NICs are on the machine?

    The DHCP client service is running, there are no event log errors, most
    servers have one NIC.

    I got it working somewhat in my test domain. I deleted the A record and
    forced a new dynamic registration as suggested in
    http://blogs.technet.com/networking...​-of-dns-scavenging-just-be-patient.​aspx.
    The record was successully updated on the DNS server the client sent the
    update to; however, the updated timestamp is not replicating between DCs. If
    the client updates with one DC but another does the scavenging I'm still in
    trouble.

    Re: failure to replicate timestamps.

    That should only be the case if Aging is not enabled on the zone.
    Otherwise it suggests a problem with replication since the timestamp is
    part of the dnsRecord attribute.

    That is probably it; we have scavenging on in production but not in test. i
    will turn it on and see if the timestamps get in sync.

    When I turned scavenging on the updated timestamps were successfully
    replicated. It appears the final answer is to disable McAfee, delete the old
    A record, and make sure scavenging is on.

  8. Disable McAfee? Did I miss something where this was mentioned earlier?

    For any AV or installed security apps , I suggest and *highly*
    recommend to exclude the NTDS and Sysvol folders. If you have
    Exchange, exclude the whole Exchange folder and subfolders, as well as
    the mailbox database/stores if located on another drive.

    And I'm glad to hear that you have a handle on this now. :)
