MCTS Guide to Microsoft Windows 7 Chapter 13 Enterprise Computing
Objectives • Understand Active Directory (AD) • Use Group Policy to control Windows 7 • Control device installation with Group Policy settings • Plan enterprise deployments of Windows 7 • Describe enterprise deployment tools for Windows 7 • Use Windows Server Update Services (WSUS) to apply updates • Understand Network Access Protection
Active Directory • Active Directory • Expands domain concept by linking: • Domains in logical structures named trees • Multiple trees into forests • Domain controllers • Servers holding a copy of Active Directory information • Authenticate users when they log on to a workstation • Respond to requests for other domain information such as printer information or application configuration • Clients use DNS to locate domain controllers • Member servers
Active Directory Structure • Domain • Central security database used by all computers that are members of the domain • Information about user accounts and computers • Active Directory uses the same naming convention for domains and objects as DNS • Organizational Units (OUs) • Each domain can be subdivided into OUs • Allow you to organize the objects in a domain • Can be used for delegating management permissions • Used to apply Group Policies • Trees and Forests
Joining a Domain • When a workstation joins a domain • Integrated into the security structure for the domain • Administration can be done centrally using Group Policy • Joining a workstation to a domain creates a computer account • After a workstation is joined to the domain • It synchronizes time with domain controllers in domain
Group Policy • Group Policy • Centrally manage the configuration of a Windows 7 computer • Settings you can configure • Desktop settings, such as wallpaper and the ability to right-click • Security settings, such as the ability to log on locally • Logon, logoff, startup, and shutdown scripts • Folder redirection to store My Documents on a network server • Software distribution
Controlling Device Installation • You can prevent/control device installation in Windows 7 • Example: • Prevent installation of USB-based storage to prevent data from leaving the premises • Types of devices you can control • CD and DVD • Custom Classes • Floppy Drives • Removable Disks • All Removable Storage classes • Tape Drives • Windows Portable Devices (WPD) • All Removable Storage classes
Deployment Planning • Formal process for implementing Windows 7 should include the following steps: • Define the scope and goals of the project • Assess the existing computer systems • Plan the new computer system configuration • Determine a deployment process • Test the deployment process • Deploy Windows 7
Scope and Goals • Organizations should not change computer systems for the sake of change • Must be significant benefits to the organization • Scope for a Windows 7 migration project defines which computers should be upgraded • Also defines the data to be migrated • Existing computer systems in organization must be evaluated • To ensure that they support Windows 7 • Evaluation is composed of two parts • Hardware evaluation • Software evaluation
New Configuration • In some cases, the default configuration of Windows 7 is sufficient for organizational need • In many more cases, the organization customizes the default configuration of Windows 7 • To match its needs • Applications must also be selected as part of the configuration planning
Deployment Process Selection • Can either upgrade existing operating system or do a clean installation • Upgrade retains all existing computer settings • User files, applications, and application settings • Clean installation allows standardized configuration • Rather than using existing settings • Potential installation methods • Boot from DVD • Run unattended setup from a network share or DVD • Imaging • Windows Deployment Services • Systems Management Server
Test Deployment • You must thoroughly test the deployment process • First part of testing should be in a test lab • Then, perform a test pilot to designated users within the organization • Users and computers selected should be representative of the users and computers in the overall organization • In most cases, deployment: • Will not be over a single night or a single weekend • Will be by department, region, building, or floor • Breaking deployment into smaller phases reduces the risk of failure
Enterprise Deployment Tools • Many tools are available to help in the deployment of Windows 7 • ImageX, Sysprep, Windows System Image Manager (WSIM), Windows PE, and Windows Easy Transfer • Additional tools • User State Migration Tool (USMT) and Windows Deployment Services (WDS) • USMT has a command-line interface that is appropriate for scripting in large scale deployments • System Center Configuration Manager (SCCM) and the Microsoft Deployment Toolkit (MDT) • VHD boot
Windows Deployment Services • Windows Deployment Services (WDS) • An updated version of Remote Installation Services (RIS) • Automates the installation of Windows clients • WDS Requirements • Active Directory • DHCP • DNS • An NTFS partition on the WDS server • Windows Server 2003 SP1 with RIS installed • Administrative credentials
VHD Boot • New feature in Windows 7 • Allows the operating system to be installed to and booted from a virtual hard disk (VHD) file instead of a disk partition • Useful for power users in large enterprises with a virtualized desktop environment • VHD boot can also be used to simplify dual booting
Windows Server Update Services • Windows Server Update Services (WSUS) 3.0 • Server component • Contacts Microsoft Update and downloads updates • Rather than each client computer downloading updates • Very efficient for network utilization • Each update is downloaded only once and stored on the WSUS server • Client computers are configured to contact a WSUS server for updates
WSUS Updates • WSUS obtains updates for the following products: • Windows clients and servers (including 64-bit) • Exchange Server • SQL Server • Microsoft Office • Microsoft Data Protection Manager • Microsoft ForeFront • Windows Live • Windows Defender
Network Access Protection • Network Access Protection (NAP) • System that enforces requirements for client health • Before allowing client computers to connect to the network • Client and server components are required for NAP • NAP is not intended to block network intruders or protect the network from malicious users • Enforcement mechanisms integrated with NAP • IPSec; 802.1X; VPN; DHCP; RADIUS
MCTS Guide to Microsoft Windows 7 Chapter 14 Remote Access
Remote Access and Remote Control Overview • Remote access • Consists of: • Dedicated computer acting as a remote access server • Other computers (mobile computers) configured to link to the server • Allows remote access clients to access resources local to the remote access server • Link can be established over a dial-up connection or a TCP/IP network
Remote Access and Remote Control Overview (cont'd.) • Remote control • Remote client uses remote control software to send keyboard and mouse commands • To the computer being remotely controlled • Commands are processed on the remote controlled computer • Remote client is sent a visual update of the screen from the remotely controlled computer
Dial-Up Protocols • Windows 7 supports the industry standard Point-to-Point Protocol (PPP) • For end-to-end communications between a remote client and remote server using dial-up connections • PPP has the ability to carry different protocols within PPP data packets • Including TCP/IP data
Analog Dial-Up Connections • Public Switched Telephone Network (PSTN) • Also called Plain Old Telephone System (POTS) • Designed to carry human voices from one phone to another as an analog signal • Analog dial-up modem • Converts digital information into analog form • Compatible with delivery over the PSTN • Main disadvantage of analog dial-up is that it is slow • Transferring below 100,000 bits of data per second
Remote Access VPN Connectivity • Data transmitted over the public network can be recorded or modified • By individuals with criminal or mischievous intent • Secure point-to-point connection can be created using VPN technology • VPN technology • Similar to remote access in that a server and client form the two endpoints of a connection • Different from a remote access connection in that it protects the data transferred between its endpoints
VPN Protocols • Communication protocols • Called tunneling protocols • Manage virtual private link and encrypt its data • Point-to-Point Tunneling Protocol (PPTP) • Allows IP-based networks to deliver PPP packets by encapsulating them in IP packets • IP packets can be routed through public networks • PPTP can be used with TCP/IPv4 and TCP/IPv6 networks • Layer 2 Tunneling Protocol (L2TP) • Encapsulates PPP packets to be sent over IP network connections • IPSec provides encryption for L2TP connections • L2TP can be used with TCP/IPv4 and TCP/IPv6 networks • Secure Socket Tunneling Protocol (SSTP) • Allows IP-based networks to deliver traffic through firewalls that would otherwise block PPTP and L2TP
Remote Desktop • Remote Desktop Protocol (RDP) • Designed to carry remote control session data efficiently and securely • Between the client and server involved in a remote control session • Remote Desktop client • Software that is used to remotely control a Windows 7 computer • Available as a stand-alone client application and as a Web client
Stand-Alone Remote Desktop Client • Most commonly used version of the client • New version designed specifically for Windows 7 and Windows Server 2008 R2 • Improvements include: • Support for Network Access Protection client updates • Bidirectional audio • Remote application task scheduler can automatically start remote applications • Ability to support up to 16 multiple monitors • Support for Aero glass
Remote Assistance • Allows a user to send an invitation to a remote user using instant messaging or e-mail • Invites them to remotely connect to the local computer • They can establish a secure remote connection to view what is happening on the desktop • Local user can electronically chat with the person providing remote assistance • Remote user can optionally be granted complete keyboard and mouse control • During the remote assistance session
Remote Assistance (cont'd.) • Windows Remote Assistance wizard • Accessed by clicking Windows Remote Assistance link in Help and Support • Can give a remote user the ability to access sensitive information and settings on a computer • Invitation to use remote assistance is password protected • Unique password selected for that specific invitation
Sync Center • Sync Center allows mobile users to quickly and easily synchronize network content on the mobile computer • When a computer is portable, one of the problems is making sure a user still has access to his/her data • Windows 7 provides Sync Center as a central control mechanism • Sync Center window lists all of the data sources that need to be cached on the local computer • Resource must be compatible with the Sync Center to be available as an item to track and synchronize
Mobility Center • Windows 7 places controls for mobile computer features in one single window • Mobility Center is a feature available only on Mobile computer • Typical controls found in Mobility Center include: • Battery status and power management • Wireless network configuration • Display configuration • Synchronization settings • Presentation settings
