Multiple dc's and dhcp servers

[Keith]

Hello all,

I am about to another dc in my network and it will also be
another dhcp server. When I configure the dhcp options
should I set the original dhcp server, named dhcp1, as the
DHCP server or make the new dhcp server, named dhcp2, as
the dhcp server?

I imagine that dhcp2 would be the dhcp server in the
options from dhcp2 since it is providing the lease or if
dhcp1 goes down but anyones opinion would be greatly
appreciated. My network is windows 2000 SP4, Active
Directory, DNS is active directory integrated. Clients are
either W2k professional or XP.

Thanks you for your time.

DHCP servers don't "co-ordinate", so each one
has to have a separate, independent range of IPs available
to lease out.

The usual way to configure redundant DHCP is to
create a large, overall scope IP range in the network for DHCP use,
and then block out all address ranges from that scope on each
server, except those that the particular server should give out.

Each server also needs to mirror all reservations and
global exclusions.

Also note that there is no real mechanism to control which
DHCP server will grant a particular request. They all
will be participating.

You must have a lot of workstations to require an additional DHCP server.
