Summary

As this chapter has demonstrated, there are many ways to add fault tolerance to network services and resources running on Windows Server 2003 servers. Moreover, each of the features discussed in this chapter is included with the installation of the operating system: no additional licensing fees for third-party software are required to add redundancy and increase availability to Windows Server 2003. Depending on the type of fault tolerance required in an organization's Service Level Agreements, there might be an increased investment in hardware. However, with server consolidation opportunities available with Windows Server 2003, organizations might find that they have freed up hardware that can be re-assigned to participate in fault tolerance solutions.
