Multi DHCP Scopes across Fiber M.A.N.

Windows 2003 D.C. Server Fully patched.
4 Cisco 1841 routers holding fiberoptic metro area network connections

Main Office: 192.168.100.0/24 DHCP managed by DC
Office 2 192.168.101.0/24 DHCP managed by Cisco router
Office 3 192.168.102.0/24 DHCP managed by Cisco router
Office 4 192.168.103.0/24 DHCP managed by Cisco router

All four locations connected together via fiber optic metro area network on
a private VLAN.


I have a domain controller issuing DHCP at my main location. At each of the
other 3 locations, the Cisco 1841 router at that location is acting as DHCP
server for that local subnet. I would prefer to centralize DHCP on the
domain controller, and still be able to keep my subnet addressing scheme as
is. I know that my routers can function as DHCP relays, but this is only one
of the options I have studied. Im not clear on how to structure this so that
each machines in each office receive an address that is correct for their
location. Some articles have inferred that RRAS would be necessary as well.
If someone can give a basic illustration of how this would work and which
network management applications have to be in the loop, i can go from there.
TIA for any advice or informative articles.
