  • Do AD Domain names and DNS zones have to match?

    Is it possible to have AD computer objects in an AD domain: SITE-1.COMPANY.COM

    when their DNS host records are in a Windows DNS zone that doesn't match the AD domain name:
    SITE-2.COMPANY.COM ?


    Here's the whole situation:


    I have a Windows 2003 AD domain: SITE-1.COMPANY.COM that serves subnet 10.10.0.0/22 at our main site. The Windows DNS zones for this site match the AD domain name:
    SITE-1.COMPANY.COM
    0.10.10.in-addr.arpa

    I have a remote site that we have a permanent VPN to, that has it's own subnet 192.168.0.0/24.

    I would like to simply add the computers at the remote site to the AD Domain at the main site, but I'm assuming that I would need to add a forward and reverse zone on my DNS server to cover that subnet:

    SITE-2.COMPANY.COM
    0.168.192.in-addr.arpa

    but they would still be in the AD domain:
    SITE-1.COMPANY.COM

    So, their AD domain and DNS zones would not match.

    Can this be done? Or is this a BAD IDEA?

    Thanks.
