am trying to use dhcp for the first time on our 2k server network.  i need about 600 addresses. at the moment i've created 3 scopes each containing 200 addresses. one on each domain controller.

is this the best way of doing it?

when the first dhcp server has allocated all its addresses, will new requests automatically be passed to the next dhcp server?

i cleaner way would be to create one scope with all 600 addresses.  Unless you have a specific reason for needing three scopes (such as they will use a different gateway or dns server) i would just use one large scope,,,, it will make it easier to manage.

I dont want all the computers to rely on 1 server, that's why i've got 3 scopes.

Browolf,,, do you have 3 DHCP scopes or 3 DHCP servers???  you only mentioned 3 DHCP scopes in your post which indicates 3 scopes on one server, which gives you no DHCP redundancy.

my bad i missed that.... well to answer your question yes when one scope runs out of addresses  the other should give out dhcp addresses from its own scope.... the way dhcp works is the client sends a broadcast looking for any dhcp server to respond, the first one responds is the server that the client will get the address from.  Since you are worried about redundancy and fault tolerance i would make your scopes much bigger though (big enough that all your clients could get addresses from one DHCP server if the other 2 were down).  I'm you are giving out private addresses so they are free, so why not make the scopes bigger?  it wouldn't hurt anything, and would only help you.
