Active-Passive Cluster, you can do this with Microsoft's clustering. It's a decent solution, I've done Active-Passive Exchange clusters and DHCP servers before.

Clustering for Linux is available too, but it has rough edges (At least with RHEL)

Marathon everRun HA is pretty good too, closer to fault tolerance. If you want real fault tolerance, checkout the Stratus FT-Servers. (99.9997% uptime)
