Windows 2000 DHCP server

Use the 80/20 rule to configure IP address ranges on different servers. This lets you configur the complete scope of IP address among two DHCP servers. If one server is offline, then the other DHCP server is still serviceing the clients request.
Example:

DHCP#1 Scope 1: 192.168.10.10 to 192.168.10.254
Exclude: 192.168.10.200 to 192.168.10.254
DHCP#1 Scope 2: 192.168.20.10 to 192.168.210.254
Exclude: 192.168.20.10 to 192.168.20.200
DHCP#2 Scope 1: 192.168.10.10 to 192.168.10.254
Exclude: 192.168.10.10 to 192.168.10.200
DHCP#2 Scope 2: 192.168.20.10 to 192.168.20.254
Exclude: 192.168.20.200 to 192.168.20.254

I would not advise using two dhcp servers. If you are concerned that your server will die then setup your dhcp lease to 14 days. this will allow you to have 14 days of the current ip adddress. on the 7th day it will try to renew the ip address andwill start communicating with the dhcp server.
Really if you do not have very complicated dchp setting. How hard would it be to add this to another server. 20 minutes tops. reboot the workstations and be off and running again. you are just cuuting into your scope of ipaddresses and wasting you time. Most computers willnot miss a beat if the dhcp server dies and will continue to work if it is off line for a day or so.

I would agree with the 2nd answer above. You also have to take into account the fact you have 2 DHCP servers to administer rather than 1.

And in real life, who can have a server down for several days at a time without management complaining?

Hi,
I agree with Answer2, The DHCP Server doesnt take more than 15 minutes to add and configure DHCP.
