dhcp server

Is it possible to have more than one DHCP server on a network at a time? or will this cause conflicts with the IP configuration.

Sure can.

The servers need to have MAC tables to decide what numbers to assign to each machine, or
the clients can request a specific number and the server which holds that will respond.
Otherwise it's the first to respond to the client. that is chosen.

Hmm I think I should refine that a bit. You sure can I have more than 1 DHCP server on 1 logical network, juts make sure that you give them different pools to choose from. (i.e. DHCP1 192.168.1.1-192.168.1.128 DHCP2 192.168.1.129-192.168.1.254) Obviously excluding your routers from the pool. If you let 2 DHCP routers roam free using the same pool you may cause problems like 2 nodes taking the same address, because I'm not sure if DHCP servers check before issuing ip's.
