how do i make a redundant server 2003 for High Availability?

Is this as confusing as it seems? I'm fairly new to this type of configuration, and somebody recently asked me about it. I thought maybe it's something like RAID 1, which a child with half a brain can do, but syncing 2 servers together seems to be a bit difficult, not clear cut as "creating" a RAID 1 array.

What about NAS drives? Can I have redundant NAS drives as well too? Just thinking in terms of high availability, and looking for some education in this case.

So my background is this: I know how to build computers. I know basic networking. I.E. Switch is different than a router. And though I don't know 100% of what a router does, I know it shares the internet. I know if I plug an internet cable into the "WAN" port, it'll share the internet. I know if I plug another router on the same network, I have to disable DHCP and assign it an IP address outside of the auto-scope and plug it into the "LAN" port.

that's basically my extensive networking knowledge. Oh yeah, mapping and sharing drives.

please help!
 
If you want to do this with Server 2k3 and physical servers, you'll want to read about Server Clustering:

Today, a lot of people achieve HA (high availability) by running a virtual machine on physical hosts that are clustered and connected to SAN storage. VMware's vSphere HA (for example) would take care of migrating the VM to another physical host if it needed to.
