Not knowing anything about networks, I need some advice.

2 servers, each with 2 processors and 2 network cards.

My manager wants to set these up on the network using load balancing and
mirroring.

I'm just wondering if this is the way to go or should we be looking at setting
up a cluster ?

OS Windows 2003 Server
IIS (I think it's 6 with 2003)
CFMX 7

I will be installing CFMX 7 using the multi server config.

Any advice would be welcomed.
