Subject: DHCP Implementation Advice

I'm new to this list, please bare with me or point me in the right direction...

My organization would like to begin using DHCP with private addressing, rather than statically assigning routable addresses.  Now while I'm confident I can implement the needed methods, I'm having some difficulty getting everything to work together.  So if anyone can offer any assistance, it would be greatly appreciated.  Here's my scenario.

1. We are currently using a class c from our T-1 provider, that we will be returning in the next 21 days when we move to a new provider in a new building.  We do have the option of giving static routable addresses out again, but we'd like to move into Private address assignment with DHCP.

2. Our network consists of a Primary Domain Controller on Windows NT 4.0.  99% of all workstations are Windows 95 or 98.

3. The new building we move into is probably going to span over 254 required IP addresses very quickly...
    First question, how do I get DHCP to span multiple networks (specify a scope of 192.168.1.1 - 192.168.254.254, subnet mask 255.255.0.0?)?

4. I was able to get a machine to distribute the IP lease information, however, clients couldn't log onto the PDC nor could they get out on the gateway I assigned.  Now I assume the gateway problem is just a matter of telling the router to route 192.168.0.0 to the serial IP on the router (maybe I'm wrong?), but why would the IP address information prevent them from logging onto the network?

Thanks for any assistance anyone can offer.
