that program developers can incorporate into their programs. Active Directory drops the 15-character domain and computer names in favor of Internet-style DNS names, such as Marketing.MyCompany.com or Sales. YourCompany.com . However, it still supports the old-style names for older client applications that don’t deal well with DNS names. Windows 2000 Server comes in three versions: ⻬ Windows 2000 Server is the basic server application, designed for small- to medium-sized networks. It includes all the basic server fea- tures, including file and printer sharing, and acts as a Web and e-mail server. ⻬ Windows 2000 Advanced Server is the next step up, designed for larger networks. Advanced Server can support server computers that have up to 8GB of memory not hard drive — RAM and four integrated proces- sors instead of the single processor that desktop computers and most server computers have. ⻬ Windows 2000 Datacenter Server is supports servers that have as many as 32 processors with up to 64GB of RAM. It’s specially designed for large database applications. For small networks with 50 or fewer computers, Microsoft offers a special bundle called the Small Business Server, which includes the following compo- nents for one low, low price: ⻬ Windows 2000 Server, the operating system for your network server ⻬ Exchange Server 2000, for e-mail and instant messaging ⻬ Internet Security and Acceleration Server 2000, which provides improved security and performance for your Web applications ⻬ SQL Server 2000, a database server ⻬ FrontPage 2000, for building Web sites ⻬ Outlook 2000, for reading and sending e-mail The pricing for Windows 2000 Server is based on the number of clients that will use each server. Each server must have a server license — and an appro- priate number of client licenses. When you buy Windows 2000 Server, you get a server license and depending on the size of your network a bundle of 5, 10, or 25 client licenses. You can then purchase additional client licenses 5 or 20 at a time. Table 8-1 lists the prices for the various types of Windows 2000 Server and client licenses. 93

With Windows NT, you had to use different programs for different server management functions, such as managing users or managing disk settings. MMC lets you perform almost all server management functions from within a single program. Windows Server 2003 By mid-2003, Microsoft had released a new version of Windows Server called ta-daaa Windows Server 2003. For several years prior to its release, this new version was called Windows .NET Server. .NET is pronounced dot-net. Windows Server 2003 builds on Windows 2000 Server, with many new fea- tures. Here are but a few of the additions: ⻬ A new and improved version of Active Directory with tighter security, an easier-to-use interface, and better performance. ⻬ A better and easier-to-use system-management interface called the Manage My Server window. On the flip side — for those who prefer brute- force commands — Windows Server 2003 includes a more comprehensive set of command-line management tools than is offered by Windows 2000 Server. Of course, the familiar Microsoft Management Console tools from Windows 2000 Server are still there. ⻬ A built-in Internet firewall to secure your Internet connection. ⻬ A new version of the Microsoft Web server, Internet Information Services IIS 6.0. 94 Part II: Building Your Own Network Like its predecessor, Windows Server 2003 comes in several versions. Four, to be specific: ⻬ Windows Server 2003, Standard Edition: This is the basic version of Windows 2003. If you’re using Windows Server 2003 as a file server or to provide other basic network services, this is the version you’ll use. Standard Edition can support servers with up to four processors and 4GB of RAM. ⻬ Windows Server 2003, Web Edition: A version of Windows 2003 opti- mized for use as a Web server. ⻬ Windows Server 2003, Enterprise Edition: Designed for larger net- works, this version can support servers with up to eight processors, 32GB of RAM, server clusters, and advanced features designed for high performance and reliability. ⻬ Windows Server 2003, Datacenter Edition: The most powerful version of Windows 2003, with support for servers with 64 processors, 64GB of RAM, and server clusters, as well as advanced fault-tolerance features designed to keep the server running for mission-critical applications. Table 8-2 lists the pricing for Windows Server 2003, which is similar to the pricing for Windows 2000 Server with the exception of the Web Edition.
