I have taken over a mess at my new job and I aslowly trying to work my way
through the carp to get to a better solution. I have just set up a new DHCP
server, but the thing is now, this one DHCP server has to assing IP address
to 4 networks.

192.168.0.
192.168.2.
192.168.3.
192.168.4.

each with its own gateway

Setting up the scopes and all that is done, but now how do I ensure that
each PC get that IP address that it is supposed to. I am assuming that I am
supposed to use a class, but how do I assing a class to a scope, and when I
create a use defined class, what BINARY and ACSI value should I use.

Thanx

the DHCP server will see from what network the request is coming (from a
special field in the DHCP request) and will give the IP address according to
that.

Unfortunately that is the thing. The only way the these "networks" are
differentiated is by location and statically assigne IP addresses. There are
no DC's for the other three networks. I know it is screwed up, but that
unfortunatley is what I have inherited.

How are these subnets linked together? DHCP requests are broadcasts. You
can usually configure your routers to relay these requests so that they can
reach a DHCP server on a different segment. The address of the router
interface which received the original broadcast determines which scope is
used. For example if the machine broadcasts a request and that request is
received on interface 192.168.0.x of the router, the machine will receive an
offer of 192.168.0.n .

yeap, Bill is right. You'll need a DHCP relay for each subnet. (most routers
can do that; if not, even a Win XP Pro can be configured to do that from
NETSH)

understand what you are all saying, it makes sense, but I must ask a few
questions.

The subnet are currenty linked via VNP, we have a CISCO 800 at group
office and netgrears down at each branch.

Then I must ask, when it comes to DHCP, what is a user defined class, and
what on earth is it used for.

Secondly, the NETSH commande, I assume it can be done from W2003 Server,
and what syntax am I looking for or what should I be searching the internet
for to get the syntax?

Thanx for all your help so far.

I would never even try to centralize DHCP in a setup like that. My
advice would be to manually configure the machines in the branches if they
don't have a server. If there is a server in a branch, configure it to do
DHCP for the local subnet.
