This essential primer traces the history of DNS through the evolution of Windows Server, from Windows NT 3.51 to the present, illuminating how the product has become an essential component of AD implementation and the Internet. DNS has experienced some growing pains, and expert authors like Mark Minasi and Mark Burnett have gone the extra mile to help you get past the most common misconfigurations and gotchas while providing the fundamentals about configuring, installing, customizing, and troubleshooting the many facets of DNS.
1. Configuring and Administering DNS
This chapter introduces Domain Name System (DNS) to the Windows Server community as part of Windows NT 3.51. It provides a basic understanding of what DNS does, how to configure it, and how to install it.
2. A DNS Primer
Mark Minasi reveals how DNS matured in Windows 2000. It discusses some DNS fundamentals, such as DNS names and addresses, name registration, the DNS hierarchy, primary and secondary DNS servers, and DNS's integration with Active Directory (AD).
3. How DNS Works
Gary Kessler provides an overview on the basics of Internet addressing, as well as information about how to get a Web address and how to register a domain name.
4. DNS and Active Directory
Mark Minasi dives deeper into AD’s connection with DNS, explaining that before you start your AD planning, you need to do your DNS homework—or even the best-planned AD implementation will run badly. Where should you put DNS forwarders and slaves—and more basically, what do those terms mean? What's split-brain DNS? And how can you make AD coexist with an existing DNS infrastructure?
5. Troubleshooting DNS-Related AD Problems, Parts 1 and 2
Mark Minasi tackles specific DNS-AD conflicts—in particular, Dcpromo-related problems. To see how things might be going wrong, he reconstructs scenarios.
6. Solving DNS Problems
Mark Minasi describes DNS as a necessary evil of AD implementation. Because of some AD-specific needs, making DNS work with AD can be problematic even for a DNS veteran. He reviews some essential principles for making DNS work in support of AD and takes a look at some cool DNS features in Windows Server 2003. He also goes into depth about an important DNS approach called split-brain (or split-horizon) DNS.
7. DNS Configuration Errors Breed AD Horror
Having trouble with AD? It might be a DNS problem. A large proportion of AD failures are caused, in Mark Minasi’s experience, by DNS problems. And most DNS problems stem from the configuration errors that he explains in this article.
8. Deconstructing DNS
DNS is easy to forget about when it's working like it's supposed to. But because DNS has become the cornerstone of a properly functioning AD environment, and because DNS is the glue that holds the Internet together, the ability to quickly spot and solve DNS problems on your network is essential. This article takes a look at the intricacies of DNS troubleshooting outside of AD, then examines the complexities that AD adds to the mix.
9. Segregate Your DNS Servers
DNS is often misunderstood and misconfigured. How you design your organization's DNS infrastructure can have a huge impact on the performance and security of your entire network. The key to effective and secure DNS design—particularly in large networked environments—is to segregate DNS servers into distinct roles, with each server dedicated to a single role. In this ideal scenario, each server's configuration, features, and zone data distinguish it from the next. Here's how to do it.
10. DNS Annoyances
Although DNS services are fundamentally simple, certain problems frequently appear. Quite often, unclear wording or poorly documented options in various Windows dialog boxes can cause these problems. This article examines some common DNS annoyances that plague administrators and how you can deal with them.
