Rod,
I just answered most of this... before I read your message, or I would have
elaborated.
There is no replication of DHCP info.
Usually, what I do is:
a. Make my subnets less than 128 computers each (if you only have one
subnet, you can use the 192.168.x.x/24 range of address if you have less
than 128 clients)
b. Set up each DHCP server with half the available IP addresses (i.e., one
server allocated from 192.168.10.1 to 192.168.10.127, and the other one uses
192.168.10.128 to 192.168.10.254)
c. Let the server's fight over who is going to answer.
(c) is an automatic process... both server's will answer a DHCP request, but
only one of those answers (the one that the client received first) will be
Acknowledged, and so one server will record the new lease, and the other
will not, and will make the "offered" address available again.
The other way to do it is to set the whole range available on both machines,
but there will be quite a bit more traffic between the server and the
machines while the server checks to see if each address is available before
dishing it out. But not a whole lot of extra traffic...

Subject: [windows2000] DHCP servers in a Windows 2000 AD network
I administer a Windows 2000 Active Directory network. However, I don't have
a lot of training at this sort of thing, but I do have some.
Anyway, I've got a question about DHCP servers in a Windows 2000 AD network.
What I would like to know is, if there is 2 or more servers that act as DHCP
servers, do they replicate information between the 2 of them? Or put
differently, if I want to make one of my servers which isn't a DHCP server,
into a DHCP server, do I have to do some sort of "copying" of information
from the previous DHCP server to the new DHCP server?
