(Select all that apply.) A Implement disk quotas on the e-mail server so that users’ inboxes cannot exceed a certain size B Increase the level of authentication security so that only Kerberos-authenticated users can access the e-mail server C Distribute an Acceptable Use Policy to your user base so that they understand what they can and cannot while using their office PCs D Use NTFS file permissions to restrict network access to personnel in your Sales and Customer Service department only Developing a Test Network Environment You are the network administrator for a law firm that has multiple locations throughout the United States.Your firm has purchased a customer relationship management (CRM) application that will be hosted in the firm’s main office in Key Biscayne, Florida, and accessed by other offices using dedicated WAN links.You would like to test the performance of this software over a WAN link before deploying it to the other offices in the firm Unfortunately, you only have access to test equipment in the Key Biscayne office location.What is the best way to test the performance of this application? A Use the average network bandwidth utilization in each office to estimate the performance of the application over the WAN B Install routers within the test lab to simulate the latency of the dedicated WAN links between offices www.syngress.com 255_70_293_ch01.qxd 9/10/03 1:42 PM Page 47 Using Windows Server 2003 Planning Tools and Documentation • Chapter C Access the CRM application from your home computer using your high-speed Internet connection D Test the application using production systems in each of the remote offices You are in the process of building a lab environment to test a new network application.You would like to isolate the test environment from your production equipment as much as possible to prevent any test changes from affecting your users’ daily tasks What can you to protect your production environment from changes performed in your test lab? (Select all that apply.) A Place a router or firewall between the network infrastructures connecting the test lab to your production machines B Keep the network cabling for the test lab physically separated from the network hardware that provides connectivity to your production environment C Contain the test lab in a separate OU D Use 100MB Ethernet for your production machines, but only 10MB Ethernet for the test lab 10 You are designing a lab environment to test a proposed upgrade to Windows Server 2003.You are in the process of creating a domain structure in the test lab to assess various features and functions of the upgrade process, including switching the domain from mixed mode to native mode and moving from a standard DNS zone to ADintegrated DNS At the same time that the Windows Server 2003 testing is taking place, you would also like to use the test lab to evaluate a new accounting package that will be implemented on the production network before the Windows Server 2003 upgrade takes place.You not want the two batteries of tests to interfere with each other.Which of the following would be good design choices for the domain structure of the test lab? (Select all that apply.) A Create two separate domains: one to test the accounting software and one to test the domain mode and DNS functionality of Windows Server 2003 B Create a single domain in the test lab to encompass the entire test environment C Create a separate OU to test the accounting software so that it will not be affected by the switch in domain mode D Create two separate forests: one to test the DNS configuration and the switch from mixed mode to native mode and one to perform the tests on the accounting software package www.syngress.com 47 255_70_293_ch01.qxd 48 9/10/03 1:42 PM Page 48 Chapter • Using Windows Server 2003 Planning Tools and Documentation 11 You have received a critical software update from the vendor of your accounting software suite.The software vendor has indicated that you should apply this patch as quickly as possible to correct a potential security breach As the administrator for your network, what should you when you receive this notice? A Install the patch on all production systems as quickly as possible B Install the patch in your network’s test lab to ensure that it functions properly and without any adverse side effects, and then apply it to all of your production systems as soon as possible C Install the patch on a single workstation on your production environment to see if there are any bugs or malfunctions.When you are satisfied, apply the patch to the remainder of your workstations D Send the software patch to Microsoft Product Support Services for testing before applying it to your network computers 12 You are the network administrator for a small company that is considering purchasing a Windows Server 2003 machine to replace an aging Windows NT Server machine The client workstations run a mix of Windows 98,Windows NT Workstation, and Windows XP Professional Each network client needs to be able to access the network server after it is upgraded, since the client workstations will be upgraded on a one-by-one basis over the course of several months.You have been informed that you will need to use the production server itself for testing, and that there is only sufficient budget to allot one representative workstation PC for test purposes.What is the best way for you to test client connectivity to Windows Server 2003? A Configure the test workstation with Windows Server 2003 Connect a production Windows 98,Windows NT 4, and Windows XP Professional workstation to the test server B Use a utility like VMware to simulate how each operating system on your network will function with the new Windows Server 2003 server C Check each client operating system one at a time, reformatting the test PC after you’ve finished testing each operating system D Connect a production Windows 98 and Windows NT Workstation to the Windows Server 2003 Configure the test workstation to use Windows XP Professional Documenting the Planning and Network Design Process 13 You have recently started working as a network administrator for a company whose network consists of multiple Windows Server 2003 domains.The previous network administrator left you with little documentation detailing how the network is configwww.syngress.com 255_70_293_ch01.qxd 9/10/03 1:42 PM Page 49 Using Windows Server 2003 Planning Tools and Documentation • Chapter ured, and you’ve discovered that many client workstations are behaving inconsistently—sometimes the Run line is unavailable, sometimes a user cannot access the Control Panel, and so on.You suspect that this is the result of Group Policy settings, and want to put together a list of all GPOs that are present within each domain on your network.What is the most efficient way of accomplishing this task? A View each domain’s settings within the Group Policy Management Console (GPMC) and take note of the values listed under the Group Policy node in each domain B Use a GPMC script to list all GPO objects within each domain C Load the Resultant Set of Policies (RSoP) snap-in to view the various GPOs that are causing client settings to be applied D Examine the Group Policy tab of each domain’s Properties sheet in Active Directory Users & Computers 14 A portion of your network is shown in the Figure 1.15.You are using Network Monitor from WorkstationB to capture network traffic for analysis.You suspect that there is an Internet Relay Chat (IRC) connection between WorkstationA and WorkstationC, but the Network Monitor trace does not show any sign of that connection.What is the most likely reason for this? Figure 1.15 Network Portion Ethernet Workstation A Workstation B Workstation C A Network Monitor captures broadcast traffic only on a Windows network B Windows workstations not support IRC connections C The version of Network Monitor that ships with Windows Server 2003 products does not operate in promiscuous mode D You need to use Performance Monitor to capture and analyze network traffic between machines on a Windows network www.syngress.com 49 255_70_293_ch01.qxd 50 9/10/03 1:42 PM Page 50 Chapter • Using Windows Server 2003 Planning Tools and Documentation 15 Your company, airplanes.com, has recently undergone a merger with southern-airplanes.com, and you have taken over the network management of both halves of the newly formed company Airplanes.com has a strict policy of desktop and software installation restrictions, while southern-airplanes.com has historically been more lenient with allowing users to customize their computers and install personal software Several of the users from southern-airplanes.com have complained about the policy restrictions that have been placed on their desktops.You have been asked to present a report to the management group detailing which restrictions are in place on various OUs.What is the most efficient way to present this information to the management group in an easily readable format?

Planning Server Roles and Server Security Introduction Planning an effective security strategy for Windows Server 2003 requires an understanding of the roles that different servers play on the network and the security needs of different types of servers based on the security requirements of your organization Securing the servers is an important part of any network administrator’s job In this chapter, we will first review server roles and ensure that you have an understanding of the many roles Windows Server 2003 can play on the network.We will discuss domain controllers; file and print servers; DHCP, DNS, and WINS servers;Web servers; database servers; mail servers; certification authorities; and terminal servers.Then we will delve into how to plan a server security strategy.We will examine how to choose the right operating system according to security needs, how to identify minimum security requirements for your organization, and how to identify the correct configurations to satisfy those security requirements Next, you will learn how to plan baseline security on both client and server machines We will cover planning the secure baseline installation parameters and enforcing default security settings on new computers.We will show you how to customize server security, securing your servers according to their roles.Then we will walk you through the process of creating custom security templates and show you how to deploy security configurations EXAM 70-293 OBJECTIVE Understanding Server Roles When Windows Server 2003 is installed on a computer, it provides a wide variety of tools and functionality However, additional features may still need to be installed on the server to bring clients the services they need.The server may need to supply file and print services, authenticate users, or support a local intranet Web site Until Windows Server 2003 is configured to supply these services, clients will be unable to use the server in a manner that is required by the organization Server roles are profiles that are used to configure Windows Server 2003 to provide specific functionality to the network.When you set up a server to use a specific role, various services and tools are enabled or installed, and the server is configured to provide additional services and resources to network clients Roles are applied to machines using the Configure Your Server Wizard and managed using the Manage Your Server tool As shown in Figure 2.1, Manage Your Server provides information about the roles that are currently configured for a server, and it provides the ability to add and remove roles from a server Depending on your server’s settings, this tool will start automatically upon logon If you’ve checked the Don’t display this page at logon check box at the bottom of this window, Manage Your Server will not start automatically.You can start it manually by selecting Start | Administrative Tools | Manage Your Server As shown in Figure 2.1, there are a variety of items in Manage Your Server’s main window.The left side of the window lists the roles currently configured for the server Beside each entry, there are buttons that relate to the corresponding role.These buttons www.syngress.com 255_70_293_ch02.qxd 9/10/03 10:58 AM Page 55 Planning Server Roles and Server Security • Chapter differ from role to role, and they are used to invoke other tools for managing the role or to view information on additional steps that can be taken to configure, administer, and maintain the role Figure 2.1 The Main Manage Your Server Window Near the top of the Manage Your Server window are three buttons.Two of these are used to obtain additional information about roles and remote administration.The other button, labeled Add or remove a role, is used to invoke the Configure Your Server Wizard.You can also start the Wizard by selecting Start | Administrative Tools | Configure Your Server When the Configure Your Server Wizard starts, it informs you of possible preliminary steps that need to be taken before a new role is added As shown in Figure 2.2, these steps include ensuring that network and Internet connections have been set up and are active for the server, peripherals are turned on, and your Windows Server 2003 installation CD is available.When you finish reading this information, click the Next button to have the Wizard test network connections and continue to the next step www.syngress.com 55 255_70_293_ch02.qxd 56 9/10/03 10:58 AM Page 56 Chapter • Planning Server Roles and Server Security Figure 2.2 Preliminary Steps

Windows Control Panel), where you can configure additional services Figure 2.3 Configuring Server Roles In Figure 2.3, you can see that there are 11 different roles that can be applied to Windows Server 2003 through the Configure Your Server Wizard.These roles are as follows: www.syngress.com 255_70_293_ch02.qxd 9/10/03 10:58 AM Page 57 Planning Server Roles and Server Security • Chapter I Domain controller This role is used for authentication and installs Active Directory on the server I File server This role is used to provide access to files stored on the server I Print server This role is used to provide network printing functionality I DHCP server This role allocates IP addresses and provides configuration information to clients I DNS server This role resolves IP addresses to domain names (and vice versa) I WINS server This role resolves IP addresses to NetBIOS names (and vice versa) I Mail server This role provides e-mail services I Application server This role makes distributed applications and Web applications available to clients I Terminal server This role provides Terminal Services for clients to access applications running on the server I Remote access/VPN server This role provides remote access to machines through dial-up connections and virtual private networks (VPNs) I Streaming media server This role provides Windows Media Services so that clients can access streaming audio and video New & Noteworthy After you select the role to add to the server, click Next to step through the process of setting up that role Each set of configuration windows is different for each server role Also, although multiple roles can be installed on Windows Server 2003, only one role at a time can be configured using the Configure Your Server Wizard.To install additional roles, you need to run the Wizard again Manage Your Server The Manage Your Server tool is new to Windows Server 2003 It is similar to the Configure Your Server utility in Windows 2000 and provides a centralized location for administrators to access tools, view information, and launch programs used to maintain specific roles In addition, servers with Internet access can benefit from this tool, because it can be used to invoke Windows Update to apply security patches, service packs, new drivers, and other updates Manage Your Server also provides links to Web pages located on Microsoft’s site, which can assist administrators in understanding how to deal with specific problems and obtaining the latest information Manage Your Server also provides a way to launch the Configure Your Server Wizard, where you can add roles to a server or remove existing ones Because the roles installed on a server can be modified at any time, administrators are able to change a server’s role on the network as needs within the organization change www.syngress.com 57 255_70_293_ch02.qxd 58 9/10/03 10:58 AM Page 58 Chapter • Planning Server Roles and Server Security Before setting up a server role (as we will in Exercise 2.1, later in this chapter), it is important to understand each of the roles that can be applied to Windows Server 2003 In the sections that follow, we will discuss these roles in greater detail and examine how they are installed with the Configure Your Server Wizard and other tools Domain Controllers (Authentication Servers) Domain controllers are a fundamental part of a Microsoft network because they are used to manage domains A domain is a logical grouping of network elements, including computers, users, printers, and other components that make up the network and allow people to perform their jobs.When a server is configured to be a domain controller (DC), it can be used to manage these objects and provide other capabilities for configuring and controlling your network An important function of a domain controller is user authentication and access control Authentication is used to verify the identity of an object such as a user, application, or computer For example, when a user logs on to a domain, he or she will enter a username and password, which is compared to information that is stored on the domain controller If the information provided by the user matches data in the user account, the domain controller considers the person to be authentic.The process continues by giving an appropriate level of access, so the user can utilize resources on the network Access control manages which services and resources users (or other objects) are permitted to use and how they can use them By combining authentication and access control, a user is permitted or denied access to network services and resources Active Directory To perform these functions, the domain controller must have information about users and other objects in a domain In Windows 2000 and Windows Server 2003, this data is stored in Active Directory (AD), which is a directory service that runs on domain controllers A directory serves as a structured source of information, containing data on objects and their attributes Objects in the directory represent elements of your network (including users, groups, and computers) Attributes are values that define an object (such as its name, location, security rights, and other features) Using tools that access AD, an administrator can manage an object’s attributes to provide information that is accessible to users and control security at a granular level By serving as a data store of information about a domain, AD is the means by which administrators achieve greater and more flexible control over a network When AD is installed, the server becomes a domain controller Until this time, it is a member server that cannot be used for domain authentication and management of domain users or other domain-based objects.This does not mean, however, that AD can be installed on every version of Windows Server 2003 It can be installed on Standard Edition, Enterprise Edition, and Datacenter Edition, but servers running the Web Edition of Windows Server 2003 cannot be domain controllers.Web Edition servers can be only stand-alone or member servers that provide resources and services to the network www.syngress.com ...
