  • How to clear DNS Host(A) Record

    Hi All,

    I've a server called citrix2000( 192.168.9.18 ) and we just reload with different name and now i need to create the host (A) record called citrix but if i ping that citrix.domain.com.au it's pinging the 192.168.9.18 ?

    i try to delete the cached lookup but didn't work?

    Any ideas?

    First of all, make sure you are querying the right DNS.
    You can use the following command:

    NSLOOKUP
    ->Server <your DNS server>
    ->citrix.domain.com.au

    Make sure that you are not getting a non-authoritive response.

    Second of all, make sure this isn't because of a local client cache - IPCONFIG/FLUSHDNS will clear the local cache buffer.

    Get back with results.

    Regards,
    Syslog.

      Another thing that I forgot to mention, if you don't have a A record in the DNS (or not using DDNS?) you could add an A record using the DNS management snap-in (Administrative Tools) to the related zone.

      Let me know if it works if ya.

          Do this (unless I'm confusing myself)
          Code:
          C:\>nslookup
          Default Server:  XXXXXXXXX
          Address:  172.18.21.66
          
          > set type=soa
          > citrix.calvista.com.au
          Server:  XXXXXXXXX
          Address:  172.18.21.66
          
          calvista.com.au
                  primary name server = 
                  responsible mail addr = 
                  serial  = 2005020466
                  refresh = 900 (15 mins)
                  retry   = 600 (10 mins)
                  expire  = 86400 (1 day)
                  default TTL = 3600 (1 hour)
          >
          Whatever the primary name server is, that's where you need to change the record, IIRC.

            Default Server: mel-pdc.domain.local
            Address: 192.168.4.1

            > set type=soa

            Server: mel-pdc.domain.local
            Address: 192.168.4.1

            domain.com.au
            primary name server = dn1.ip.com.au
            responsible mail addr = admin.domain.com.au
            serial = 2005020466
            refresh = 900 (15 mins)
            retry = 600 (10 mins)
            expire = 86400 (1 day)
            default TTL = 3600 (1 hour)

            but this IP.com.au is the one host that dns for our web site? but i need to change only from internal not external.

              Okay... So how would you like the A record to resolve?

                Looks like your internal DNS is scr*w*d up.
                What DNS zones do you have defined in your DNS?
                Do you have any entries for calvist.com.au zone?
                Do you have DNS forwarders configured in DNS properties?

                citrix.calvista.co.au

                answers with an external IP on my server - is that correct?
                TIA
