  • WINDOWS 7 CLIENT SEARCHING FOR DOMAIN CONTROLLER WHILE ON EXTERNAL NETWORK

    We have a windows 2003 server as a domain controller and few windows 7 x 64 bit clients attached to this domain. When these clients are on external network and connect to our Head office server to run an application such as Qlikview we find that the application plugin does not get launched on further investigation found that it is trying to contact our local DC for DNS resolution The error is given below please guide ABCnbk.XYZ.IN.SHIPPING.COM
    Description:ABCnbk.XYZ.IN.SHIPPING.COM
    Description:
    Name resolution for the name IN.SHIPPING.COM timed out after none of the configured DNS servers responded.

    Is your application exposed to the external network?
    Is your DC reachable from the external network?
    Can you post an IPCONFIG/ALL from a computer inside the domain network and also in the external network

      I would say that your DNS records aren't published externally and as such they won't work.

      Do your clients connect via a VPN tunnel to the office when working externally?

      Can you add a hosts entry that will resolve to an external record?

        Please find our network setup details for better understanding

        Parent Domain : SHIPPING.COM - Country A
        Our Local DC : XYZ.IN.SHIPPING.COM - Country India

        We connect with Cisco VPN client to the parent domain network in Country A and can access the resources there but we cannot access resources of our local network through that VPN connection. When we run Qlikview application it is able to resolve the IP and go through the VPN and bring the opening page but at the second level of authentication it shows the above mentioned DNS error the qlikview error log shows as below
        2015-09-01 15:24:34 Error Connect .\ClientAuthentication.cpp 166 Could not InitializeSecurityContext 1265 The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.

        same machine on external network instead of logging in with domain username i login with a local username then qlikview works fine
