    First let me say I'm sorry if this question has been asked before (I'm sure
    it has) but, my brain is just not functioning today. I have a Windows 2003
    domain we will call abc.com. Currently all users in the company use DHCP to
    get an ip address and the DHCP server is configured to push down 015 DNS
    Domain Name "abc.com". As a result, any queries for A-records that exist in
    the domain abc.com are resolved. Now the company wants to add a sub-zone to
    the dns called stores.abc.com. They want all their DHCP clients to be able
    to resolve any A-records in abc.com & stores.abc.com. Can I configure DHCP
    to push this change down to the client's? If so, how? If not, any
    suggestions.

    As always, thank you.

    No, you cannot configure to push this change down to the clients. Within
    DHCP, you can only push down one suffix only, when it comes to DNS. :)
    But, help can be found by leveraging Group Policy. Append a DNS Suffix
    Search List for all your DNS domains to your Windows XP clients DNS Suffix
    search list order under TCP/IP properties via Group Policy. By using an
    explicit DNS suffix search list pushed out by GPO, use of a short name
    allows the machine to attempt resolution with each entry in the search list.
    Set this via a Domain GPO.

    Default Domain Policy
    Computer Configuration
    Administrative Templates
    Network
    DNS Client
    DNS Suffix Search List: Enabled

  3. DHCP can only assign the connection DNS suffix, which is added to the DNS
    suffix search list. If the AD domain is abc.com then the primary DNS suffix
    will be abc.com and is also in the DNS suffix search list. So you can
    concievably set the primary DNS suffix search list to abc.com and the
    connection DNS suffix to stores.abc.com and have both in the DNS suffix
    search list.
