The next step in the installation process is to install the networking services that are needed for the server. To install the networking services, you can use either of a couple of different approaches—use wizards or manually add services.

In Windows Server 2003, Microsoft has added a set of wizards that allow you to configure the server to support different roles, such as an Application Server with Internet Information Server (IIS) or a Domain Controller with Active Directory. The wizards automatically walk you through the installation of the network services needed to support the roles you select.

After the newly installed system reboots, log on as Administrator using the password assigned during installation. The Manage Your Server Wizard is displayed with two options available:

Because only the initial installation has so far been performed, no roles have been added, and the only option available is Add Or Remove A Role. This option launches the Configure Your Server Wizard, which allows you to add and remove server roles and the corresponding services. As discussed in the section entitled "Planning for Server Usage", it is common for a server to fill multiple roles, especially on smaller networks. The Windows Server 2003 server roles are as follows:

When selecting multiple roles for a single server, try to select roles with different resource needs. For instance, putting a processor-intensive role, such as Application Server, and a role that does a lot of network input/output (I/O), such as File Server, together on a single system makes more sense than putting two roles that both require a lot of processor time or that both require a lot of network I/O.
