In this chapter, I’ll take a look at four major networking services that commonly are used in Windows Server 2003 installations—the Dynamic Host Configuration Protocol, which helps administrators with IP address management, the Routing and Remote Access Service to manage inbound connections from VPN users, the IP Security service to encrypt IP traffic between computers, and the network access quarantining control feature to protect your network from untrusted clients.
This chapter has a practical focus. Entire books can be (and have been) written on each of these topics, so I cannot possibly cover all of them in depth. Because of the vast amount of resources already available, I’ve chosen to focus on providing instructions for configuring these protocols to work under Windows Server 2003 rather than overwhelm you with page after page of theory. I discuss the mechanics a bit, but I place more emphasis on hands-on activities. At the end of the chapter I provide a comprehensive list of resources if you want more theory and background on these networking topics.
The Dynamic Host Configuration Protocol (DHCP) assists administrators by automatically configuring computers with IP addresses, saving the hassle of assigning and tracking static IP addresses among multiple machines. When DHCP is coupled with dynamic DNS, a technique you learned about in Chapter 4, a lot of administrative headaches formerly ...
