    2 Domains on 1 IP Range.

    Hi I need a little help in trying to get my new network running. I've inherited a school where they have one (semi broken cc3) domain (domain A), a 2nd (vanilla) domain (Domain B). For a short while (lets say a period of 3 months) they need both domains to run on the same network simoultaneously.

    What's the best way to go about this. Can I run Domain A and domain B on the same DHCP Scope, obviously both have their own DHCP, DNS servers.

    What I've come up with is I will exclude an IP range on Domain A (lets say 50 addresses) extending the exclusion as and when required. I will then statically assign the clients on domain B the excluded ip addresses, until such time where I will be in a position to completely switch off domain A.

    I have configured WDS on domain B. During the middle of the day when its reasonably safe that everyone has turned their computers on and have an IP assigned,

    1) I switch off dhcp and dns on domain A
    2) Activate the dhcp scope on domain B,
    3) Build the stations that I need to,
    4) Then deactivate dhcp on domain B
    5) and reactive dns and dhcp on domain A.

    I have set my WDS to listen for unknown clients, but without an activated dhcp scope on domain B the pxe boot process does not pick up an IP address.


    Is there a better way to get these two domains working on the same range simultaneously, or I just have to put up with this long winded process until they are back on one domain?

    Domain A with a shortened DHCP scope and Domain B with a limited scope for exactly the number of addresses needed which are allocated via reserved IP addresses. Or DHCP reservations for both?

    Yes I've seen this many times - one DHCP scope but two domains with a trust. Absolutely pointless these days, but back in the days of Windows 98 it was considered more necessary.

    ah yes ofcourse, If i reserve the mac address of the client for an IP in Domain B, i then don't need to set a static ip, and so avoiding a second visit to the machine to change ip allocation to DHCP, once domain A is decommissioned.

    Nice one. I'll test that.. but I'm not sure with two DHCP servers running, how do I stop the client from getting an IP from DHCP on Domain A

    Use AD without DNS integration. Setup two DNS zones on the same server. DHCP with one scope.
