Flashcards in Windows Server Administration Deck (83)
Factors for choosing the OS edition for your servers:
- the hardware in the computers
- the features and capabilities you need
- the price of the OS
The four basic editions of Windows Server 2008:
- Windows Web Server 2008. For Internet or intranet servers. Connor be an AD domain controller. Cannot run client/server apps that are not web based.
- Windows Server 2008 Standard. Only lacks some high-end components like server clustering and AD FS. Limited to computers with up to 4 GB of RAM (for x86) and up to four processors.
- Windows Server 2008 Enterprise. The full set of features. Supports computers with up to 8 processors and up to 64 GB of RAM (for x86) and up to 4 virtual images with Hyper-V (for 64-bit version) and an unlimited number of network connections (Terminal Services Gateway connections).
- Windows Server 2008 Datacenter. Only available from OEMs bundled with a server. Designed for large and powerful server with up to 64 processors and fault tolerance features such as hot add processor support.
Hyper-V is only available on what version of Server Core?
Roles available in Server Core installation:
- Active Directory Domain Services
- Active Directory Lightweight Directory Services
- DHCP Server
- DNS Server
- File Services
- Print Services
- Web Server (IIS)
- Streaming Media Services
Roles NOT available in Server Core installation:
- Active Directory Certificate Services
- Active Directory Federation Services
- Active Directory Rights Management Services
- Network Policy and Access Services
- Windows Deployment Services
- Application Server
- Fax Server
- Terminal Services
- UDDI Services
(Not intended as a platform to run server applications, only for running mission-critical server roles.)
Two ways to work with a Server Core computer:
Command line or remotely with the MMCs on other computers.
Graphical applications available on Server Core:
- Registry Editior
- Task Manager
- Some Control Panel elements like Date and Time and Regional and Language Options
Preboot execution environment (PXE)
A network adapter feature that enables a computer to connect to a server on the network and download the boot files it needs to run, rather than booting from a local hard drive. Uses Windows PE.
Windows Deployment Services (WDS)
A role included with Windows Server 2008, which enables you to perform unattended installations of Windows Server 2008 and other operating systems on remote computers, using network-based boot and installation media. The client computer must have a network adapter that supports PXE. Uses .wim file-based images files.
Microsoft Assessment and Planning Solution Accelerator (MAP)
A free tool that can perform hardware inventories on computers (servers or workstations) with no agent software required on the client side (evaluates all the computers on the network of the computer it is installed on). MAP can then evaluate the hardware information and create reports that perform a variety of preinstallation tasks. Need to have Office and SQL Server installed, and requires a new database instance for its exclusive use.
WDS includes the two following role services:
- Deployment Server
Full install of WDS, requires Transport Server. For full remote OS installs.
- Transport Server
Only the core of WDS, to create namespaces that enable you to transmit image files using multicast addresses.
Prerequisites for WDS:
- Active Directory
- NTFS drive
Windows Preinstallation Environment.
A subset of Windows Server 2008 that provides basic access to the computer's network and disk drives, making it possible to perform an in-place or a network installation. This eliminates DOS from the installation process by supplying its own preinstallation environment.
A stripped-down, command-line version of the OS from which you can perform a full OS install. Unlike earlier DOS boot environments, it provides full internal support for 32- or 64-bit device drivers, TCP/IP networking, NTFS drives, and various scripting languages.
Single instance storage
A Windows technology that enables a .wim file to maintain a single copy of a particular OS file and yet use it in multiple OS images. This eliminates the need to store multiple copies of the same file.
WDS requires two types of image files to perform remote client installations:
- Boot image. Contains the files needed to boot the computer and initiate an OS installation. boot.wim
- Install image. Contains the OS the WDS will install on the client computer. install.wim
A collection of images that use a single set of files and the same security settings. Using an image group, you can apply updates and service packs to all of the files in the group in one process.
Can be used to deploy an OS to a computer that is not PXE-enabled. Must burn the discover image to a medium and boot the computer from it - it loads PE, connects to the WDS server, and install the OS.
When DHCP is not installed on the same computer as WDS (a custom DHCP option):
• Clear the "Do not listen on port 67" and Configure DHCP Client Option 60 to PXEClient" checkboxes in the WDS configuration wizard
• Manually configure the external DHCP to include the custom option that provides WDS clients with the name of the WDS server. (only affects network boots)
Boot image files are downloaded using:
Trivial File Transfer Protocol (TFTP)
Capture boot image
An image that you boot from that captures an image of the computer for uploading to the WDS server.
Prepares a computer before capturing an image of it (generalizes it). Included with Windows Server 2008.
Answer file/unattend file
A text or XML file containing responses to the user prompts that typically appear during a Windows OS installation.
To create answer files:
Use the Windows System Image Manager (Windows SIM) tool in the Windows AIK.
To install an OS on a client using WDS with no interactivity, you must have 2 answer files:
• WDS client answer file - to automate the WDS client procedure
• OS answer file - to automate the standard OS installation
Windows Automated Installation Kit.
A set of tools and documents that enable network administrators to plan, create, and deploy OS image files to new computers on the network. Not included with Windows Server 2008 but is a free download.
The primary tools included in the Windows AIK:
• Windows PE
• Windows RE
• Windows SIM
A command line program that can capture, transfer, modify, and deploy file-based images from the Windows PE environment. Used to create a Windows PE disk image.
Windows Recovery Environment.
A command line OS, similar to Windows PE, in which you can run diagnostic and recovery tools.
Windows System Image Manager.
A graphical utility that creates and modifies the answer files you can use to perform unattended OS installations on remote computers.
