Primary and secondary AD integrated DNS

    Question

  • Hi

    we have below setup

    A->1 Domain controller(Windows Server 2008 SP2 x64 bit) with Schema and domain FSMO role with AD integrated DNS on it

    B->1 Domain controller(Windows Server 2008 R2 x64 bit) with Infrastructure, PDC emulatore and RID FSMO role, DHCP with AD integrated DNS on it.

    Now i think both DNS server will act as primary DNS server.

    what i want to know is that on client we have mentioned two DNS server entry A is preferred DNS Server and B is alternate DNS server.

    So what i wanted to know say if my A server goes down should i able to nslookup and resolve my DNS records or not.

    I have tried but it won't resolve.

    Regards

  • Hi Devang,

    You are right. The DNS should reply your request if it´s configured properly. Try to check local on the DNS (open DNS MMC, right click on the server, "nslookup"

    The DNS entries are replicated by AD

    Maybe the server is not configured to reply for your network? 

    Kind regards,

  • Thanks Philip

    Records are replicated perfectly to both dns servers.

    i'm also able to launch nslookup successfully on both the dns servers.

    still i face below problem

    So what i wanted to know say if my A server goes down should i able to nslookup and resolve my DNS records or not.

    I have tried but it won't resolve.

  • what happens if you try to nslookup from client?

    nslookup 

    server firstdns.domain.local

    myrecord.domain.local

    then the secound....

    nslookup 

    server secounddns.domain.local

    myrecord.domain.local

    maybe you a firewall blocks something!
