Tom,

I can see why Bob doesn't understand the situation. I don't and I
doubt that you do either.

You do not have too many machines for one DHCP server to handle. It can
handle thousands of machines in multiple scopes without any trouble. It can
also handle multiple networks which are linked by routers as long as the
routers can handle DHCP relay.

Your problem seems to be more of a routing problem that a DHCP problem.
Where are these two networks located? How are they linked together?

They are located in separate buildings a few blocks apart and are connected
by a dedicated T1 line with ethernet convertor boxes on each end. I'm
currently connected directly from a switch in one network to a switch in the
other.

Are you trying to tell us that you have two segments which are linked by
one of the servers? If that is the case you can simply run two scopes on the
W2008 server and enable DHCP relay on the machine connecting the two
segments to solve the DHCP problem.

I think this is the answer to my problem. We have one network that has a
192.168.1.x scope of addresses and the other that uses 192.168.2.x addresses.
On the W2008 server do I need to setup a super scope or just 2 normal scopes
- 1 that is serving 192.168.1.x and the other that is 192.168.2.x addresses?

How are you routing the traffic in the 192.168.2.x subnet? Are you using
the W2k3 server as a RRAS router? You will need to make some changes to your
scope and also the your gateway router to get that to work. Here is a setup
which will do that.

Not using RRAS routing. Here is how it is currently setup.

Internet
|
router/firewall
192.168.1.1

Content Filter
192.168.1.50
|
WServer 2008 DC
192.168.1.2 (DHCP server with two scopes)
192.168.1.x and (192.168.2.x - superscope)
| |
Switch Switch
| |
LAN1 machines LAN2 machines
192.168.1.x 192.168.2.x
from scope 1 from scope 2

The machines on LAN1 are fine. The machine on LAN2 will only connect the
the W2008 Server, but won't route to the internet. Is that where DHCP
relaying
comes into effect. Thanks for your patiences. I've always dealt with small
networks with only IP scope and am learning as I go.
