Steve has never liked them.Whilst i see his point i generally have no problems pointing forwarders to my ISP's DNS unless we have an unreliable ISP who break stuff and then i dont like them anymore. But i can could on one hand the amount of times this has happened to either me or the networks i look after.

Do what ever takes your fancy. There is not hard and fast right way as such in your situation, if i read it correctly.

    Hello everyone.

    Would someone clear this for me? It’s a bit off topic.

    Domain controller (192.168.0.a) ß--à (192.168.0.b) ISA
    (192.168.1.c) ßà (192.168.1.d) LinkSys Router ßà ISP

       1. If I want to add forwarders to dns tab of domain controller,
          should I put the internal side ip address of router or
          should I put the one from ISP?
       2. Does domain controller cache DNS requests too pretty much
          like http caching? Or does it go and ask every single time
          there is query.

    Appreciated
