need advice/help for installing 2 internet connections in 1 server

[nzuser]

Hey everyone :)I havent touch networking for ages and i just got a new project to do..anyway i just did a fresh install of server 2003 sp2 and got my AD, DNS, DHCP up and running and now i having a bit problem and need your pro to help me :(
here is the story / project:
- I have 2 connections using thier own ISP router ( 1 for staff and 1 for student)
- Server, xp computers, 2 ISP routers and a printer connecting to a big hub
- i want student to connect to Router(A) and have ip range from 192.168.100 ~ 192.168.180 ( i done this thru DHCP ) and router IP 192.168.0.1
- i want staff to connect to Router(B) and have ip range from 10.10.200.10 ~ 10.10.200.30 ( i done this thru DHCP ) and router IP 192.168.0.254
i want staff to be able to login and the configuration will pick up using Router B and student will use Router (A)..and now i start getting lost
i have played with the setting and it is not going anyway :(, am i suppose to set up 2 DNS? or 1 Scope in DHCP or assign something special at ACTIVE Directory GPO to achieve this project?
Thank you so much~

Doing your research before beginning a project is always advisable so you don't dig yourself in hole you can't get out of.

Dhcp happens far below the influence of a GPO

You have no control over what pc gets what ip address in this setup.
For this scenerio to work you would need two routers that had dhcp relay with one configured to pass thru the 10x net and the other to pass thru the 192x net to the switches/pcs attached to that router.

So you would have your server connected to a switch that had the two routers connected which in turn each router would connect to a switch that one switch has the teachers and one switch has the students. This same switch that the routers are connected to would also have the two internet routers connected to them.

Kinda a mess isn't it?

I would have gone the route of a single subnet range and do static ip assignments to both teachers and students. On the student pcs I would have used a restrictive gpo and microsoft's steady state to keep the pcs from being configured by the students.
The static assignments would have allowed you to set what gateway was to be used.
