Are you really sure you need a caching nameserver... ?

The cache, needs well... something to cache... Usually that something 
is 'the Internet' ;) however in your case, it will be the authoritive
server for your intranet (you do have one, right. or not... ?).

Now, if my guess is right, you actually want to setup a DNS server 
that is authoritive for your local domains (and not a caching server).
Make sure you choose your internal domainnames wisely, it is 
advisable to avoid creating internal TLDs that are used publicly 
(that is instead of naming your internal domains: accounting.com 
management.com and so on, name your local domains using a TLD like 
.i or .0 whatever that are safe to use).

Good luck,
