Question : Only pulling IPs from one DCHP on a Dual DHCP network

I have come into an office that was set up with dual DHCP servers, a Netgear RT314 Router and a Windows NT server.  We were able to access the internet via the router (192.x.x.x IPs) and could release/renew to get IPs from the NT server (10.x.x.x).  The NT Server was also an application server, so if users needed work with these apps they would HAVE to get their IP from here.  Internet access was achieved by release/renew, which would prompt the router to assign IPs and therefore allow I-net access.

This weekend my boss upgraded the NT to a 2000 server.  Now we can no longer release/renew and switch between IP ranges.  Presently, the router is leasing the IPs first, and it appears the 2000 server is not receiving requests, or perhaps the router is just answering requests before the 2000 DHCP can lease out an address.  Hard coding the address (10.x.x.x) allows us to use the applications we need on the 2000 server.  Problem is we must then go back and switch to the 192.x.x.x range to give I-net access.  There are about 50 users in the office, so you can see this is unpractical

We would PREFER to have one IP assigned by the 2000 server to allow I-net and application access.  But neither of us are network savvy and do not understand all of the subtleties involved.  Our first thought was be to disable the DHCP server on the router, but then we will need to configure I-net access from the 10.x.x.x IPs (2000 server).  Can anyone either offer a solution or at least point us in the right direction?  Thanks!

Answer : Only pulling IPs from one DCHP on a Dual DHCP network

I would turn off the dhcp on the router and use only the dhcp in the 2000 server. Create a scope on the server with the 192 ip range and in the scope options put the routers ip address as the gateway address, that way people can acces the applications on the server and have access to the internet. The 192 adress range is private address space and the router is using nat to provide the acces to the internet. Or you can keep 10 ip scope that is on the server and change the ip of the router to an address on that range, perhaps 10.x.x.219 and put that in as the gateway address on the server scope options. Make sure that the ip that you assign to the router is excluded from the ip range on your server's dhcp scope.

example: dhcp scope range 10.100.0.5-10.100.0.200 since you only have 50 machines this range should give you more than enough ip address's. Server address 10.100.0.1, router adress 10.100.0.219.

In addition you need to make sure any printers that have print servers need to be static ip's and reserved or excluded from the dhcp range.

Hope this is plain
