Whatever protocols are installed on the server Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com 648 Chapter 13  Managing Remote Network Connections Answers to Review Questions 1. D. The Point-to-Point Tunneling Protocol (PPTP) is not a connec- tion mechanism. 2. A. You can create server-side connections through Administrative Tools  Routing and Remote Access. Client-side connections are created through Control Panel, Network and Dial-up Connections. 3. C. When you install RAS servers or VPN servers, you have the option of installing a Remote Authentication Dial-In User Service (RADIUS) server, which is used to manage RAS servers centrally by providing a central authentication database. 4. A, D. The only authentication services that are provided by RAS server are Windows authentication and RADIUS authentication. RADIUS authentication requires a RADIUS server. 5. A. Extensible Authentication Protocol (EAP) is an authentication pro- tocol that allows the RAS server and the remote access client to negoti- ate an authentication scheme, such as Generic Token Card, MD5- Challenge, Transport Level Security (used with smart cards), and S/Key. 6. D. The PAP protocol uses plain text passwords and is the least secure authentication protocol. 7. C. CHAP is a challenge-response authentication protocol. It is used by non-Microsoft clients to provide challenge-response authentication using the Message Digest 5 (MD5) hashing scheme to encrypt the response that is sent from the RAS client to the RAS server. 8. D. Multilink connections are used to allow several physical connections to be combined into a single logical connection. This allows you to combine several slow-speed lines into a single logical higher-speed line. 9. B. The Bandwidth Allocation Protocol (BAP) or the Bandwidth Allocation Control Protocol (BACP) can be used to control how much bandwidth will be allocated to a specific connection. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Answers to Review Questions 649 10. A. The Microsoft Point-to-Point Compression Protocol (MPPC) is used to compress any data that is sent over the remote access or demand-dial connection. 11. C. In the Event Logging tab of the RAS server Properties dialog box, you can specify whether Point-to-Point (PPP) logging is enabled. If you enable PPP logging, all of the events related to the PPP connection process will be written to the \Windir \Tracing\ppp.log file. 12. C. Port settings are not configured as a part of the remote access profile. 13. C. On a domain controller, you assign permissions to users who can access an RAS server through the Dial-in tab of the user Properties dialog box in the Active Directory Users and Computers utility. 14. C. VPN servers allow remote computers to connect to the network through the Internet. 15. D. When you install an RAS server, by default, it will try to install whatever network protocols you have installed on your server as the remote client protocols.

Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com O ne way to make sure that your Windows 2000 system is working at its best is to keep it up to date. Using the Windows Update utility, you can check for and download the latest software, such as drivers. You’ll also want to install Windows 2000 Server service packs as they become available, to fix bugs and sometimes add new features. To have an optimized system, you must monitor its performance. The tools for monitoring Windows 2000 Server are System Monitor, Performance Logs and Alerts, and Task Manager. With these tools, you can track memory, pro- cessor activity, the disk subsystem, the network subsystem, and other computer subsystems. This chapter begins with discussions of the Windows Update utility and service packs. Then you will learn how to monitor and optimize Windows 2000 Server using the System Monitor, Performance Logs and Alerts, and Task Manager utilities. You will also learn how to manage processes. The procedures for monitoring and optimizing Windows 2000 are the same for both Windows 2000 Server and Windows 2000 Professional. Keeping Windows 2000 Up to Date A n optimal operating system is one that is running the most up-to-date software and has had the most recent service pack installed. Microsoft provides the Windows Update utility to help you obtain updated Windows 2000 software. Microsoft issues service packs as necessary to update the operating system with bug fixes and new features. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Keeping Windows 2000 Up to Date 653 Using the Windows Update Utility The Windows Update utility connects your computer to Microsoft’s Web site and checks your files to make sure that you have all of the latest and greatest updates. To use Windows Update, you must first have a valid Internet connection. Then simply choose Start  Windows Update to go to the correct URL for updates. For product updates, click the Product Updates option on the home page and follow the directions to choose which files you want to update. The files in the update section are arranged by the following categories:  Critical updates  Picks of the month  Recommended updates  Additional Windows features  Device drivers Within each category, you will see the available updates, along with a description, file size, and download time estimate for each update. Just check the files you want to update and click the Download icon to download your selections. Using Windows Service Packs Service packs are used to deliver bug fixes (and sometimes new features) to Windows operating systems. Windows 2000 offers a new technology for service packs called slipstream . With slipstream technology, service packs are applied once, and they are not overwritten as new services are added to the computer. This means that you should not need to reapply service packs after new services are added, which sometimes was required when Windows NT 4 service packs were applied.  Microsoft Exam Objective Deploy service packs. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com 654 Chapter 14  Optimizing Windows 2000 You can determine if any service packs have been installed on your computer by using the winver command. To issue this command, select Start  Programs  Accessories  Command Prompt. In the Command Prompt dialog box, type winver and press Enter. You will see a dialog box that shows which service packs are currently installed. Using System Monitoring Tools B efore you can optimize the performance of Windows 2000 Server, you must monitor critical subsystems to determine how your system is currently per- forming and what (if anything) is causing system bottlenecks. Windows 2000 Server ships with two tools that you can use to track and monitor system perfor- mance: the System Monitor utility and the Performance Logs and Alerts utility. You can access the monitoring tools by adding the System Monitor snap-in and the Performance Logs and Alerts snap-in to the MMC. The System Monitor snap-in is added as an ActiveX control. In Exercise 14.1, you will create a management console for monitoring system performance.  Microsoft Exam Objective Monitor and optimize usage of system resources.  Microsoft Exam Objective Optimize disk performance. Copyright ©2000 SYBEX , Inc., Alameda, CA www.sybex.com Using System Monitoring Tools 655 All of the exercises in this chapter can be performed from either your Windows 2000 member server or domain controller. In Windows NT 4, the functions of the System Monitor utility and the Performance Logs and Alerts utility were implemented in the Performance Monitor utility.
