An Introduction to Windows Server 2008 Server Manager 1-800-COURSES www.globalknowledge.com Expert Reference Series of White Papers Introduction When you take your first look at Windows Server 2008, you'll find that many of the traditional tools that graced Server 2003 are still around: the Computer Management console; the System Information utility; the Services console; and so forth. Administrative Tools are still in a Start menu folder named "Administrative Tools," and you can start feeling fairly comfortable with the GUI if you have background with prior versions of Windows. If you have logged some flight time with Windows Vista, things will look even more familiar. Windows Server 2008 has the look and feel of Windows Vista. (Which makes sense, when you consider that both products were developed under the "Longhorn" moniker , and share many megabytes of code.) The new collapsible Start menu, the Vista-style search facilities, as well as some of the tools (such as Windows Firewall with Advanced Security) look just as they do in the Vista GUI. Where things change a bit is in the Server Manager console (ServerManager.msc, typically under C:\Windows\System32), which is really the "nerve center" of Server 2008. Parts of this console are simply con- venient pointers to other administrative tools. However, the "Roles" and "Features" nodes may be unfamiliar to you. This white paper introduces the Server Manager console and will help you find your way around it, so that you can get up to speed with Server 2008 more quickly than I did when I first started stumbling around this massive console! Version note: For this white paper, I installed Server 2008 Enterprise Edition, Beta 3 (build 6001), into a fresh Virtual Machine running on Virtual PC 2007, with the Virtual Machine Additions. The host system was Windows V ista Ultimate . What Is Server Manager? Server Manager is an administrative "cockpit" for managing virtually everything about a Windows 2008 Server machine. It combines capabilities that were spread across several consoles in Windows 2003: Configure Your Server , Manage Your Server, the Windows Optional Components wizard of the Add/Remove Programs control panel, the Security Configuration Wizard, and so on. It is quite possible that many server admins will be able to do almost everything they need to do from this one console. Of course, like other MMC consoles, you have the flexibility to create your own customized version of this tool, but I'd recommend spending some significant time with the "vanilla" Server Manager before you do so. Note that Server Manager is not the same as the "Initial Configuration Tasks" console (ICT) that comes up automatically the first time after you install Server 2008. You can use the ICT to assign an administrator pass- Glenn Weadock, Global Knowledge Instructor & Developer, MCSE, MCT, A+ An Introduction to Windows Server 2008 Server Manager Copyright ©2007 Global Knowledge T raining LLC.

You can use confidence intervals to answer this question (credit: comedy_nose/flickr) Chapter Objectives By the end of this chapter, the student should be able to: • Calculate and interpret confidence intervals for estimating a population mean and a population proportion • Interpret the Student's t probability distribution as the sample size changes • Discriminate between problems applying the normal and the Student's t distributions • Calculate the sample size required to estimate a population mean and a population proportion given a desired confidence level and margin of error Suppose you were trying to determine the mean rent of a two-bedroom apartment in your town You might look in the classified section of the newspaper, write down several rents listed, and average them together You would have obtained a point estimate of the true mean If you are trying to determine the percentage of times you 1/4 Introduction make a basket when shooting a basketball, you might count the number of shots you make and divide that by the number of shots you attempted In this case, you would have obtained a point estimate for the true proportion We use sample data to make generalizations about an unknown population This part of statistics is called inferential statistics The sample data help us to make an estimate of a population parameter We realize that the point estimate is most likely not the exact value of the population parameter, but close to it After calculating point estimates, we construct interval estimates, called confidence intervals In this chapter, you will learn to construct and interpret confidence intervals You will also learn a new distribution, the Student's-t, and how it is used with these intervals Throughout the chapter, it is important to keep in mind that the confidence interval is a random variable It is the population parameter that is fixed If you worked in the marketing department of an entertainment company, you might be interested in the mean number of songs a consumer downloads a month from iTunes ¯ If so, you could conduct a survey and calculate the sample mean, x, and the sample ¯ standard deviation, s You would use x to estimate the population mean and s to estimate ¯ the population standard deviation The sample mean, x, is the point estimate for the population mean, μ The sample standard deviation, s, is the point estimate for the population standard deviation, σ ¯ Each of x and s is called a statistic A confidence interval is another type of estimate but, instead of being just one number, it is an interval of numbers The interval of numbers is a range of values calculated from a given set of sample data The confidence interval is likely to include an unknown population parameter Suppose, for the iTunes example, we not know the population mean μ, but we know that the population standard deviation is σ = and our sample size is 100 Then, by the central limit theorem, the standard deviation for the sample mean is σ √n = √100 = 0.1 The empirical rule, which applies to bell-shaped distributions, says that in ¯ approximately 95% of the samples, the sample mean, x, will be within two standard deviations of the population mean μ For our iTunes example, two standard deviations ¯ is (2)(0.1) = 0.2 The sample mean x is likely to be within 0.2 units of μ 2/4 Introduction ¯ Because x is within 0.2 units of μ, which is unknown, then μ is likely to be within 0.2 ¯ units of x in 95% of the samples The population mean μ is contained in an interval whose lower number is calculated by taking the sample mean and subtracting two standard deviations (2)(0.1) and whose upper number is calculated by taking the sample ¯ mean and adding two standard deviations In other words, μ is between x − 0.2 and ¯ x + 0.2 in 95% of all the samples ¯ For the iTunes example, suppose that a sample produced a sample mean x = Then the unknown population mean μ is between ¯ ¯ x − 0.2 = − 0.2 = 1.8 and x + 0.2 = + 0.2 = 2.2 We say that we are 95% confident that the unknown population mean number of songs downloaded from iTunes per month is between 1.8 and 2.2 The 95% confidence interval is (1.8, 2.2) The 95% confidence interval implies two possibilities Either the interval (1.8, 2.2) ¯ contains the true mean μ or our sample produced an x that is not within 0.2 units of the true mean μ The second possibility happens for only 5% of all the samples (95–100%) Remember that a confidence interval is created for an unknown population parameter like the population mean, μ Confidence intervals for some parameters have the form: (point estimate – margin of error, point estimate + margin of error) The margin of error depends on the confidence level or percentage of confidence and the standard error of the mean When you read newspapers and journals, some reports will use the phrase "margin of error."
