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.

Why cells in the eye differ so dramatically from cells in the liver? Whereas each cell shares the same genome and DNA sequence, each cell does not turn on, or express, the same set of genes Each cell type needs a different set of proteins to perform its function Therefore, only a small subset of proteins is expressed in a cell For the proteins to be expressed, the DNA must be transcribed into RNA and the RNA must be translated into protein In a given cell type, not all genes encoded in the DNA 1/2 Introduction are transcribed into RNA or translated into protein because specific cells in our body have specific functions Specialized proteins that make up the eye (iris, lens, and cornea) are only expressed in the eye, whereas the specialized proteins in the heart (pacemaker cells, heart muscle, and valves) are only expressed in the heart At any given time, only a subset of all of the genes encoded by our DNA are expressed and translated into proteins The expression of specific genes is a highly regulated process with many levels and stages of control This complexity ensures the proper expression in the proper cell at the proper time 2/2 .. .Introduction are transcribed into RNA or translated into protein because specific cells in our body
