Configuring Server Roles and Features

• A role is a major server activity, such as providing file services or acting as a DHCP server

• A feature is software you add, such as Windows PowerShell or Group Policy Management, to help the server perform its tasks

Windows Server 2008 Server Features

• .NET Framework• BitLocker Drive Encryption• Failover Clustering (FC)• Windows PowerShell• Recovery Disc (RD): RD is a Windows utility that

creates an OS installation disc, which you may use to recover data on a corrupted installation without the original installation medium, or where standard recovery tools are inaccessible.

• Network Load Balancing (NLB) NLB distributes a workload among many other servers

Adding roles and features

• After you complete the initial configuration of your server, you may still need to add or remove roles and features. Windows Server 2008 provides two additional methods of performing this task: – the Server Management console and the– ServerManagerCmd command line utility

“command line version of server management console”

The Server Manager console

• The Server Manager console is the tool you should use for management tasks

• If the server manager window doesn't appear by itself after closing the initial configuration tasks window , you can access it by:– Choose Start Programs Administrative Tools ➪ ➪

Server Manager➪– Double-click the Server Manager entry in the

Administrative Tools folder of the Control Panel

Using ServerManagerCmd.exe

• ServerManagerCmd.exe– It is the Command-line version of server manager– Used for:

• Managing server roles• Manage features that are to be added or removed

• Management activities– Install a role or feature– Remove a role or feature– Query to determine what roles and features are

installed

11

Using ServerManagerCmd.exe (continued)

• Management activities (continued)– Determine which features and services will be

installed by a specific role, before actually installing that role

– Restart the computer after installing or removing a role or feature

– Specify particular features or services to install with a role

The Server Manager console

• No matter how you open the Server Manager console, you see a summary like the one shown next slide

• This summary includes information such as the number of roles and features you have installed, the security features you have in place, and the resources you have available
