Tom,
1) If you don't need separate AD domains you can consider reducing them down
to one
2) For now, you could just set up a two way trust
3) Ideally you would want at least two DC's for a domain anyway
4) This has no bearing on DHCP
5) Sharing an internet connection is just a routing matter. It does not
affect domains or DHCP
6) As you have a server in each subnet, you can just leave it at that. Each
server can run DHCP for its own subnet.
7) If you ever wanted to, you can run more than one subnet on one DHCP
server. You use an ip-helper address to forward requests from each subnet to
the DHCP, where it answers with the relevant scope.
Hope that helps,
Anthony

Thanks for the response Anthony. Sorry I didn't explain it better. The
problem is I have 2 primary domain controllers on the same network. They
were separate networks, but once they were connected with the T1 they now
are
sharing the same Internet connection. They server different domains. Ex.
example.com and example1.com. The each are running their own DHCP server
with different IP addressing Ex. 192.168.1.x and 192.168.2.x. We have to
many machines to have just one scope. So should I make one of the servers
a
secondary domain controller and join the domains?
Thanks,
Tom

Tom,
Not sure if I understand the question correctly.
A DHCP server can serve more than one scope. On the "other" subnet from
the
server you need to add an ip-helper address or some other way of
forwarding
the DHCP request from the client. This is normal practice when splitting
a
LAN into VLANS.
You can also have more than one DHCP server serving a subnet, but they
can't
have the same range of addresses to give out. You need to use exclusions
to
keep different ranges on different servers. There is no way in MS to
share
the DHCP database of leases.
Hope that helps,

Hello,
I currently have 2 office buildings each with their own dc and dhcp
servers.
However, we are going to connect the 2 buildings for internet purposes,
but
need to maintain the separate IP scopes. How can I have both dhcp
servers
running and have them only give a certain range of IPs for each
building.
Ex. Building one uses 192.168.1.x
Building two uses 192.168.2.x
Thanks for the help.
Tom
