Anyone knowledgable in DNS, please help

What's the difference between a 'conditional forwarder' and a 'forwarder entry'. Or are they the same thing?

Are there any advantages to using a 'conditional forwarder' insted of a 'stub zone' other than a stub zone will cache and therefore use more harddisk resources and less network bandwidth?

thanks in advance

I think I figured out my 2nd question:

A stub zone lists the authoritative DNS servers for zone. Then tells the clients in it's domain to query those servers for hostname resolution.

With conditional forwarding the server itself will query the other domain's server then provide the information to the client(this is also called recursive resolution).

Sorry man...thought it might be usefully.

A forwarder will pass all unresolved queries to a specified DNS forwarder
A conditional forwarder will pass on unresolved queries of the type you specify to a forwarder. i.e configure the DNS server to pass all queries for the example.dom to server 192.168.0.2
