Session 3: Monitoring and Managing Windows Vista 33 The Group Policy settings that control device installation are: • Allow administrators to override device installation policy. • Allow installation of devices using drivers for these device classes. • Prevent installation of drivers that match these device setup classes. • Allow installation of devices that match any of these device IDs. • Prevent installation of devices that match these device IDs. • Prevent installation of removable devices. • Prevent installation of devices not described by other policy settings. 34 Session 3: Monitoring and Managing Windows Vista Demonstration 6: Controlling Device Installation In this demonstration, you will see how you can: • View the device ID of a hardware device. • Prevent the installation of a device. Key Points The key points of this demonstration are: • Group Policy settings can prevent the installation of devices. Session 3: Monitoring and Managing Windows Vista 35 Remote Management Introduction In a corporate environment, there are huge efficiencies that can be gained by remotely managing computers. Windows Vista offers improved Remote Management support with an enhanced version of Remote Assistance and the implementation of Windows Remote Management. Objectives After completing this section, you will be able to: • Describe Remote Assistance. • Explain the Remote Assistance improvements. • Describe Windows Remote Management. 36 Session 3: Monitoring and Managing Windows Vista What Is Remote Assistance? In a corporate environment, Remote Assistance allows help desk workers to connect to a user’s computer from their own desktops. When connected to the user’s computer, help desk workers can see exactly what problem the user is experiencing. In addition to viewing the computer screen, with the user’s permission, help desk workers can take control of the computer and fix it remotely. By using Remote Assistance, problems are fixed faster because the help desk worker gets more accurate information about problems and does not have to visit the user’s desktop to perform fixes. The end result is that help desk costs are reduced and users are more productive. You can offer Remote Assistance to a user, or users can invite someone to remotely assist them. Invitations for Remote Assistance can be saved as a file. You can save that file and move it by any means you want. Alternatively, you can send the invitation directly by e- mail message. Session 3: Monitoring and Managing Windows Vista 37 What Are the Improvements in Remote Assistance? Remote Assistance has been improved in Windows Vista to address some of the common concerns found in previous versions of Windows. This makes Remote Assistance even more effective as a tool in Windows Vista. The Windows Vista Remote Assistance improvements are: • Redesigned as a stand-alone application within Windows Vista. This makes Remote Assistance faster. • Improved networking support. This allows Remote Assistance to function through network address translation (NAT) firewalls and use less bandwidth. • Added session logging. This allows users and administrators to track what has been performed during a session. • Added diagnostic tools. This makes it easier to resolve problems on remote computers. • Added reconnect after restart capability. This allows trusted helpers to reconnect to the same computer without a new invitation or users reaccepting the connection. • Added support for two viewers. Two helpers can connect to a computer at the same time. This allows two people to collaborate on fixing a problem at the same time. 38 Session 3: Monitoring and Managing Windows Vista Demonstration 7: Using Remote Assistance In this demonstration, you will see how you can: • Invite another user to remotely assist you. • Remotely assist another user. Key Points The key points of this demonstration are: • Remote Assistance is an effective way to troubleshoot workstation problems in a corporate environment. Session 3: Monitoring and Managing Windows Vista 39 What Is Windows Remote Management? Windows Remote Management (WinRM) is the Microsoft implementation of the WS-Management protocol. The WS-Management protocol is a standard that describes how systems can access and exchange management information by using a Web service. For example, WS-Management describes how configuration information can be queried remotely from a computer. Because WS-Management is a standard, it is supported by the management software of many vendors. By including WinRM in Windows Vista, Microsoft allows remote monitoring and management of Windows Vista by multiple versions of system management software. WinRM is typically not used by network administrators. It is used by developers to query and update remote computers. However, network administrators need to understand how to enable and test WinRM to ensure that system management software is able to communicate with Windows Vista. WinRM is not enabled by default in Windows Vista. The command-line tool Winrm can be used to configure and test WinRM. 40 Session 3: Monitoring and Managing Windows Vista Demonstration 8: Configuring Windows Remote Management In this demonstration, you will see how you can: • Configure Windows Remote Management. • Query Windows Remote Management. Key Points The key points of this demonstration are: • Windows Remote Management is used by system management software to monitor and configure remote computers. Session 3: Monitoring and Managing Windows Vista 41 Automated Management Introduction Automated management is any system you can use to perform system changes without user or administrator intervention. For example, you can use Group Policy to install software automatically. Windows Vista improves automated management by including the Reboot Manager service to reduce system reboots. In addition, Task Scheduler has been significantly enhanced. Objectives After completing this section, you will be able to: • Describe Reboot Manager. • Describe Task Scheduler. • Explain the Task Scheduler trigger enhancements. • Explain the Task Scheduler action enhancements. • Explain the Task Scheduler security improvements. • Explain the other Task Scheduler improvements. 42 Session 3: Monitoring and Managing Windows Vista What Is Reboot Manager? Reboot Manager is a Windows Vista component that reduces the requirement to reboot Windows or restart applications during installations. Reboots and restarts are reduced for both application installations and operating system updates. Current versions of Windows require application and operating system restarts when files are in use. For example, the operating system must be restarted after applying an update, so that Windows begins using the new files. Or, an application must be shut down before it can be updated. Restarts are a problem for automated software installation. If a user leaves an application open overnight with unsaved data, the automated installation of software fails because the user is unavailable to respond to a prompt to save work. Only after the user selects to save the work does the application close and the automated installation of software is completed. Restart Manager solves the problem of restarts in most situations. For operating system updates, Restart Manager analyzes the application request and restarts only the necessary services. For application updates, Restart Manager can save the current state of an application, update the application, and restore the state of the application. This means that applications can be updated silently without users losing their work. To gain the full benefit of Restart Manager, applications must be written to use the functionality of Restart Manager. In addition, applications must be rewritten not to request user permission to shut down.
