Error 105 DNS Issue


  • Hello,

    We are experiencing a strange DNS effecting our ability to connect to only one particular website seemingly at random. Previously we could connect without any issues. In the past couple of weeks users will type in the web address and we get an error in the browser that the address cannot be resolved. Chrome returns Error 105 and we have tried Firefox and IE and get similar messages in each. There are no errors in the DNS log but if I clear the cache on all DNS servers the issue goes away for a while before coming back again. Using nslookup we can definitely see that it’s failing at our DNS servers. If I switch to  a public DNS server we can get to the site every time. I am looking for help troubleshooting what might be causing this. Please let me know what additional information I would need to provide.

    Thank You,

    EDIT: Sorry, OS is Server 2008 R2 running

  • Hello,

    unfortunate you didn't mention the OS version you are talking about.

    See here about EDNS0

    If this is in a domain then assure to use domain internal DNS servers on the domain machines NICs and configure the FORWARDERS in the DNS management console for the DNS servers.

  • Thanks for the response and I updated my question. We are using server 2008 R2. I followed the link in your reply but unfortunately I do not believe this is the issue. Any additional information you can provide would be appreciated.

  • Check your DNS forwarder setting in your DNS's console and on your server NIC card.

    Seem to me a problematic's zone in one of your public DNS that your DNS try to get an answer from.

    Try nslookup by specifing the public server.

    I doutbh you use the same public DNS on the client than your server setting.

    If the same, check if you use WINS
