Hi!
I have a network with 2 Active Directory domains. Currently IP addresses are supplied to the network from one DHCP server. What I need is for each domain to have its own DHCP server on the same physical network. I'm doing ok until I get to the point where a client needs to be configured.
How do I tell a workstation (XP) which DHCP server on the network to use? Or am I going about this the wrong way? I've read a few articles on running multiple DHCP servers but I can't find this issue addressed anywhere. They say I can (run multiple DHCP servers) but... how?
Thanks!

Workstations find a DHCP server by sending broadcast requests out over the LAN, with an available DHCP server detecting the request and responding. To run separate DHCP servers and make sure workstations don't use the wrong one, the broadcast packets need to be blocked/restricted so they cannot pass to the wrong DHCP server.
A VLAN or running your networks off firewalled routers is probably the best method to do this.
In that case this approach will work only if the firewall is configured to allow the ports with the two switches on to communicate with each other, but not transfer UDP packets between the two ports. However, unless you are sure this can be done with your firewall (something I can't assist with) a layer 3 switch with IP Helpers would be a much better route with regards to keeping complexity and administration to a minimum.

You need to segregate these domains to separate subnets.
You best bet would be to use VLANS if you have a layer 3 switch. It will make life much easier.
You cant tell a workstation what DHCP server to use, the work station does a broadcast and what ever server answers is the one that assigns the IP.
