Deleted DNS Records Showing Back Up Again

Discussion in 'DNS Server' started by DigitalJanitor, May 21, 2010.

  1. I have a Windows 2003 domain. I have a server that is multi-homed.
    One of my colleagues configured one of the NICs to have an internal private
    IP address of 172.16.x.x which is our internal network and the other to have
    a different private IP 192.168.250.x that goes to our new data domain. The
    problem is, when he did this he left the check mark to register the DeDup
    NIC in DNS when we only wanted the internal NIC registered. After
    correcting the configuration the DeDup 192.168.250.x address keeps popping
    back up in DNS which reeks a little bit of havoc with connectivity. We have
    deleted the entry in DNS several times now from every DNS server but it
    keeps popping back up the next day. Where should I be looking for this
    address? Is it cached on one of the DC's and get's populated in again from
    that or ???

    Any help would be greatly appreciated -
    Jon

    Sorry for this way to contact you, trying to send an email but it is blocked.
    Or do you have a new one? Mine didn't change.

  8. Everyone that sent me a note about this thank you very much. It is NOT
    a DC but the situation seems to have fixed itself. The entry hasn't shown
    back up for a number of days now so I'm thinking it's taken of of in AD/DNS.

    Thanks again -
    Jon

    I have the some problem like DigitalJanitor.
    But in Windows 2008 Std R2. I configured the second network and changed DNS config. After fail result deleted the entry in DNS several times.
    In the event Server not resolving itself (nslookup fails), cant connect computers to domain etc. In network is one domain controller - AD, DNS, DHCP server.
    First I want to cleanly delete DNS and reinstall it correctly. Please help me. I realy don't want to reinstall servers and ~100 pc's in 40 hours. After thar system will have to function.

    ystem will have to function.

    It's my understanding that a fully functional DNS is a prerequisite for
    starting AD. In Windows 2003 AD needs a minimum of four DNS entries:

    CNAME DsaGuid._msdcs.your.domain.name
    SRV _ldap._tcp.pdc._msdcs.your.domain.name
    SRV _ldap._tcp.gc._msdcs.your.domain.name
    SRV _ldap._tcp.dc._msdcs.your.domain.name

    Starting with those four records an AD will automatically populate its
    own zone with the missing (typically SRV) records. Perhaps this explains
    the resurrection of deleted records in your Domain.

    The unique GUID of the host is the key to the CNAME record. It unlocks
    everything, at least name wise.
