How to implement dhcp and dns servers

[Guest]

I have been asked to research how to implement a primary and a secondary
dhcp server. I have also been asked to research how to implement a primary
and secondary dns server. Any help on where to find information on how to do
these things would be greatly appreciated.

I have been asked to research how to implement a primary and a secondary
dhcp server.

There is no such thing as a primary and backup DHCP Server. You can have
two or more of them (if done properly) but they are all equals,...there is
no concept of a primary -vs- backup.

I have also been asked to research how to implement a primary
and secondary dns server. Any help on where to find information on how to do
these things would be greatly appreciated.

Same as with the DHCP,...they are all equal,...the client simply uses them
in the order that they appear in the TCP/IP settings on the client. The
client (to my knowledge) will not switch the next on the list simply because
a name didn't resolve,...it will go to the next on the list if the previous
DNS completely didn't respond at all (it's dead, powered off).

A DNS Server can use a list of Forwarders but that is not really the same
thing as a "backup".

Barring some terminology issues in your question (which Phillip resolved),
all you have to do is to install two W2K3 servers on your network. Then
install dns and dhcp on each (configured properly). They will perform
exactly as you state, providing redundancy for both dns and dhcp. One would
do fine, but you would not have any redundancy.
