I would have thought it's be pretty easy to set up a script to repeatedly ping (or ask for the same DHCP lease?) the primary, and start/stop the service on secondary as appropriate. I'm a *nix man myself tho - so i'm not gonna try that on win!

    If you were feeling really clever you could sniff unacknowledged DHCP reqs, but that sounds like too much fun.
    It doesn't, by default. Although you can turn it on iirc. Splitting the range 50/50 also works well, I used to do that, although with 40 odd subnets it's easier to have just the one and restore the db to the second DC for now

    tmc: nothing "wrong" but it is a bit of a hack, it isn't deterministic, by which I mean you can't guarantee what's going to happen.

    Also, if you have a fairly dense IP population, you will find that if a server fails, you may run out of space. However, with 3 like you have, you'll at least have 66% left.

    It doesn't, by default
    Windows DHCP doesn't hand out addresses by default.

    Probably a good thing - got to be careful in networking products to have the user make positive choices in order to run services etc.

    Doesn't check for duplicate IP's by default. There's an option for it
