Introduction

Information in this Chapter

Intro to Windows 8 and Windows Server 2012

Intro to IPv6

Networking is a key component of any environment. Windows 8 and Windows Server 2012 offer a wide range of networking features and functionality. It’s important that you understand these features and functionality so that you can properly secure them. But, before we get into those, we will start with some more general information. In this chapter, we will start with an overview of some of the key components of Windows 8 and Windows Server 2012 that will help you as we go through the rest of the chapters. Then we will move into a discussion of IPv6, and how it’s implemented in Windows 8 and Windows Server 2012.

Intro to Windows 8 and Windows Server 2012

When you look at Windows 8 and Windows Server 2012, the first thing you will notice is a big difference in the UI. But, that’s not the only difference. There are some important differences in the management of the operating systems. There is a new Server Manager console that offers new management functionality and there has been increased functionality built into Powershell.

Server Manager

In Windows Server 2012, Server Manager has been enhanced to provide greater management and monitoring functionality. It’s your starting point for a lot of general administrative functions you will need to perform. You can access event and performance information. You can also install new roles and services from here.

Dashboard

When you log into Windows Server 2012, Server Manager will open. You will be presented with the Dashboard view, as seen in Figure 1.1. The Dashboard view allows you to access information about different roles and services that have been installed on the system. You can view information on manageability, events, performance, and BPA results.

Figure 1.1 Server Manager Dashboard View

Local Server

The Local Server section, as seen in Figure 1.2, will give you detailed information about the server to which you are currently connected. You can view server properties, events, services, Best Practices Analyzer information, performance information, and roles and features information.

Add Roles and Features

Server Manager is where you go to Add Roles and Features to your server. In upcoming chapters, we will be installing different roles and features. Most of these installs will be launched from Server Manager. The first few steps of all the installs will be the same. So, instead of repeating these steps multiple times, we will go through these steps now:

1. In the Server Manager Dashboard, select Add Roles and Features. This will launch the Add Roles and Features Wizard. First, you will be presented with the Before You Begin screen, as seen in Figure 1.3. This screen describes what can be done using the wizard. It also gives configuration suggestions to follow before you continue with the wizard. Click Next.

Figure 1.3 Add Roles and Features Wizard Before You Begin Screen

2. Next, you will see the Installation Type screen, as seen in Figure 1.4. You have two options. You can install roles or features on the system; or you can install VDI (Virtual Disk Infrastructure) services on the system. Select Role-based or feature-based installation, and click Next.

3. Next you will see the Server Selection screen, as seen in Figure 1.5. Here, you can choose to install to a server or to a VHD (virtual hard disk). If you choose a VHD, you have the option to install to a VHD attached to an online server, or to install to an offline VHD. Select Select a server from the server pool. Then choose the server you want to install onto, and click Next.

Config Export

One useful feature of the Roles and Features Wizard is the ability to export an installation configuration. After you have finished configuring the settings for an installation, you have the option to save the configuration to an XML file. You can then use Powershell to script an install with the same settings on a different server. This not only makes it easier to install multiple servers, but it also helps to ensure consistent installations. The command you would use to perform the install is as follows:

Install-WindowsFeature-ConfigurationPathFile <exportedconfig.xml>.

Notifications

The Notifications section of Server Manager, as seen in Figure 1.6, will provide notification and alert messages. For example, after you install a role, a notification will be posted letting you know that the install was successful. You will also get a notification after an install, if there is post-install configuration that needs to be done.

Manage

The Manage menu provides you the ability to add and remove roles and features. You can add servers to be managed by Server Manager. You can also create server groups.

Tools

The Tools menu brings up a list of various tools that you can use to manage your server. There are entries for Local Security Policy, Performance Monitor, Resource Monitor, the Security Configuration Wizard, and many other options. Some of these security-related tools will be covered later in this book.

Powershell

Powershell is a very powerful management language used with Windows system. Windows Powershell is a combination command-line shell and scripting language. Powershell allows access to COM and WMI managementcomponents. This greatly expands the potential of the Powershell language.

Powershell is one of the main tools used for managing Windows systems. In fact, many Windows management consoles are actually built on top of Powershell. Powershell includes a hosting API that can be used by GUI applications to access Powershell functionality.

Powershell commands can be executed as cmdlets, Powershell scripts, Powershell functions, and standalone executables. The Powershell process will launch cmdlets within the Powershell process. Standalone executables will be launched as a different process. As Windows moves forward, there will be an increasing reliance on Powershell. It’s important that you understand how to use it to manage and administer your systems. As we go through this book we ...
