    DNS Problem

    Locked

    by cshanyee ·

    Hi,

    I?m having some problem with my DNS server recently. When I do nslookup,

    C:\>nslookup msn.com
    Server: server1.site1.domain.com
    Address: 172.30.20.8

    DNS request timed out.
    timeout was 2 seconds.
    *** Request to server1.site1.domain.com timed-out

    When I do another query again via nslookup, it able to answer:

    C:\>nslookup msn.com
    Server: server1.site1.domain.com
    Address: 172.30.20.8

    Non-authoritative answer:
    Name: msn.com
    Address: 207.68.172.246

    The gateway is a firewall which forward dns query to ISP DNS server.
    The server is able to resolve host in internal domain.
    Pls adv what is the reason for DNS request timed out.

    Thanks

    Shan

        hey, this looks good:
        “DNS Request Timed Out” Error Message When You Start Nslookup From a Command Line

        SYMPTOMS
        When you start Nslookup from a command line, the following error message may be displayed:
        DNS request timed out

        timeout was x seconds
        Can’t find server name for address xxx.xxx.xxx.xxx: Timed out
        Default servers are not available
        Default Server: UnKnown
        Address: xxx.xxx.xxx.xxx
        where xxx.xxx.xxx.xxx is the Internet Protocol (IP) address of the host on which you are attempting to start Nslookup.
        CAUSE
        When Nslookup starts, it attempts to resolve the IP address of its host’s DNS server to its fully qualified domain name (FQDN). If the DNS server does not respond or if the DNS server’s reverse lookup zones do not contain a PTR record for the DNS server’s IP address, the error message is displayed.
        RESOLUTION
        If the host is configured to point to itself for DNS name resolution, verify that the DNS service is starting without error and that a PTR record exists in the appropriate reverse lookup zone.

        You can manually create the PTR record if your DNS server does not have dynamic updates enabled. If dynamic updates are enabled, you can create the PTR record by typing the following command at a command prompt:
        ipconfig /registerdns

      At first I thought is the same nslookup problem as ?DNS Request Timed Out error message when start Nslookup from a command line? but is not. Pls refer to below, when query yahoo.com for the first time encountered DNS request timed. However when query for 2nd time, it managed to answer.

      C:\>nslookup
      Default Server: server1.site1.domain.com
      Address: 172.30.20.8

      > yahoo.com
      Server: server1.site1.domain.com
      Address: 172.30.20.8

      DNS request timed out.
      timeout was 2 seconds.
      *** Request to server1.site1.domain.com timed-out
      > yahoo.com
      Server: server1.site1.domain.com
      Address: 172.30.20.8

      Non-authoritative answer:
      Name: yahoo.com
      Addresses: 216.109.112.135, 66.94.234.13
