I strongly suggest that you setup DHCP on your domain controller. In AD a DHCP server
has many more options that a router and also acts as a proxy to register reverse zone
pointer records in dns for domain clients. Now you can get by without a reverse zone
and secure dynamic updates and possibly get your domain to work acceptably but it is
not that hard to do it right.

http://www.microsoft.com/windows2000/en/server/help/default.asp?url=/windows2000/en/server/help/sag_DHCP_imp_InteroperabilityDNS.htm

Since you are on separate subnets with individual routers, you can still leave the
other network to have the router be it's DHCP server. Keep in mind that in W2K AD
domain dns configuration is crucial and the domain controller must point to itself
and the domain members must point to the domain controller ONLY as their preferred
dns server in tcp/ip properties either via static configuration or via DHCP scope
otherwise you will have a LOT of access problems. See the link below for more
specifics on W2K dns including how to set it up to allow domain clients to access the
internet via configuring the AD domain controller to use "root hints" or forward to
ISP dns server. -- Steve
