Given the information provided in the Troubleshooting Lab, answer the following questions: 1.

Reconfigure the Network Load Balancing cluster servers to use unicast mode rather than multicast mode.

The cause of the problem might be that the router connecting the Web server LAN to the rest of the company network does not support the use of multicast MAC addresses. This inability would prevent the Network Load Balancing Manager on a different LAN from communicating with the Web servers. Changing the cluster servers to unicast mode would eliminate the multicast addresses, enabling the communication to take place.

If the router connecting the Web server LAN to the company network does not support multicast MAC addresses, adding a second network interface adapter would not by itself resolve the problem, because the servers would still use the same multicast address.

Replace the router connecting the Web server LAN to the company network with a com puter running Windows Server 2003 that you have configured to function as a router.

If the router currently connecting the Web server LAN to the company network does not support multicast MAC addresses, replacing the router with a Windows Server 2003 router would resolve the problem.

Exam Objectives in this :

Identify client operating system default security settings. Identify all server operating system default security settings. Plan for security monitoring. Plan a change and configuration management framework for security.

When you install an operating system on a computer, the Setup program creates a default configuration that, from a security perspective, might or might not be suitable for your network environment. When designing a new network, you should keep security in mind from the start, and select your hardware and software with support and security capabilities as criteria. When designing a deploy ment plan for your computers, you should create a baseline installation that provides a secure starting point for the final configuration. For the majority of your systems, the baseline configuration should be adequate. For computers with extraordinary security requirements, you can build on the baseline installation by modifying the default configuration settings or by installing additional security hardware and software. Designing a baseline operating system installation is crucial to creating a secure network and smooth-running technical support. As a network administrator, you must understand the security capabilities of the operating systems on your network and be familiar with the default security settings that the installation program creates. You configure many of the security settings discussed in this chapter with tools that network administrators use every day, so the more famil iarity you have with these tools, the better.

This chapter requires only a basic understanding of the Microsoft Windows Server 2003 family s interface and of the operating system s security features. To perform the prac tice exercises in this chapter, you must have installed and configured Windows Server 2003 using the procedure documented in About This Book.

Selecting the appropriate operating systems for your network s servers and worksta tions is essential to deploying an effective network installation. A well-governed network has policies that control which operating systems are permitted for the types of computers your organization uses and the roles that the computers play. Before you evaluate computers for purchase, you should have prepared a list of hardware require ments for each role your computers have to fill, based on the hardware products supported by the operating systems you plan to use. You should also have policies in place regarding how long you expect the organization to be using the computers and how frequently you will be upgrading the operating systems and applications.
