DNS design

    Question

  • Hi,

     

    I have some questions about DNS and how to design this essential service. I will try to describe my situation and my questions as follows:

     

    I have 2 domains running,  let’s call the domains a.a and b.b. In domain a.a DNS is running on the domain controllers with AD-integrated zones. But in domain b.b DNS is running on a Linux-based BIND-implementation. This works OK but now I want to move DNS for domain b.b to Windows-based DNS with AD-integrated zones. Between the domains there is established a 2-way trust.

     

    In addition, DHCP for all subnets (with clients from both domains)  is running on the domain-controllers for a.a.

     

    So my questions:

    • Should I run DNS for domain b.b on the domain-controllers for b.b, or will it work OK to run DNS for b.b on the same DNS-servers as for domain a.a, in other words on the domain-controllers for a.a?
    • If I run DNS for both domains on the same servers, will the domain-controllers for b.b be able to register all necessary records for the domain b.b?

  • I'd put DNS for b.b on the b.b domain controller.

    a.a clients should have address of a.a DC for DNS and b.b clients should have address of b.b DC for DNS

    - Recommendation is configure AD-integrated DNS,so you should configure dns on a DC.

    - You should manually create records from both domain.
