Windows Server 2008:
Windows Server 2008 is the upgrade to the most important product line of Windows from Windows 2000 Server, with a range of scanning capabilities and a redesigned center opening a new era of 64-bit computing. Like its stable mate Windows Vista, Windows Server 2008 has been a time in the development painfully long, and some its features were originally planned for its predecessors, Windows Server 2003 and Windows Server 2003 R2. Unlike Vista, however, the schedule has long been a problem. In fact, it probably worked to the advantage of product: This is a refined performance, mature and stable system that will undoubtedly supply systems server of all kinds in the coming years.
Although Windows Server 2008 uses an enhanced version of Active Directory (AD) infrastructure debut first time in Windows 2000, many features this new operating system are radical and revolutionary. Key among these developments are important Server Core, which offers a light version server for the specific workload, and Hyper-V hypervisor-based virtualization from Microsoft. (The latter technology is currently only is available in beta version, see below for details.) As befits a major upgrade to Windows Server, however, Windows Server 2008 also includes a small number of advanced and significant functional improvements in scalability, reliability, manageability, performance and security
Charting changes: A look at the features of the new Windows 2008 server
Windows Server 2008 is the update feature rich with many functional advantages over its predecessors. Some changes in this version I think it will impact the largest customer.
Componentization with a goal
Microsoft has completely redesigned Windows Server to be functionally modular, a major change that has important ramifications. At a high level, modularity enables a system easier to maintain, both Microsoft and its customers. It also provides a safer and more reliable, because communication and dependencies between components is minimized.
In particular, modularity allows some of Windows Server 2008 delivers new management more interesting as their tools of image-based deployment, based on roles, and Server Core.
Server Manager
While the versions Windows Server earlier with separate management consoles for all the different roles and functions in the operating system, Windows Server 2003, a simple board tools for managing your server, Windows Server 2008 provides the new Server Manager. This is a true boutique one-stop shop for managing daily needs and is the only tool that many managers have to use Windows regularly.
MMC Server Manager provides a user interface for managing each installed role and feature in the system, including Active Directory Domain Services, Application Server, DHCP server, DNS server, file services, Terminal Services Server, Web Server, and many others. It also includes many troubleshooting tools very valuable, as the observer Events, Services and the reliability and performance of public services, such as configuration tools Task Scheduler, Windows Firewall, WMI Control, and the Administrator devices, and Windows backup server again.
What makes Server Manager even more useful is that each section of the console user interface becomes its own dedicated page, each of which contains relevant information about the role or function fingertips, and links to solve problems, more information and access to other tools. It is a thoughtful application is well designed, logical and useful.
Server Core
Unlike previous versions of Windows Server, most editions of Windows Server 2008 product can be installed in two modes, the traditional server graphical user interface we've had since Windows NT 3.1 and a baseline environment control light called Server Core. In this new mode of installation, Microsoft has stripped almost all graphical user interface, so no shell (start menu, taskbar, Windows Explorer, etc.), and little in the way of applications end user, things like Windows Media Player, Internet Explorer and Windows Mail are absent, but some GUI applications like Notepad and Task Manager are still available. For most, the user interface you see on Server Core is a command line window simply floating on a background of empty blue. This is the last counter-demonstration.
So what's the point? Server Core is designed to reduce the attack surface of the server to be as low as possible. As such, a Server Core installation is also more limited than that of a standard Windows Server 2008 installation. He argues that nine of the functions, including AD, AD LDS, DHCP, DNS, File, Print, virtualization (Hyper-V), Web server, and WMS, compared to 18 functions in the entire server.
Because Server Core is Windows Server 2008, all the management tools familiar GUI works great distance on this server. That will not work, and more features missing is something that requires a true graphical user interface o. NET Framework. This cancels some key features of Windows Server 2008, unfortunately, as ASP NET. Core Server Web Server function is almost static, with the argument that the old technologies such as ASP NET.
I hope that Server Core will be very popular as a infrastructure (AD, DNS, DHCP, File, Print) and a server low cost, low-end servers on the Web. Is a product that should compete well with solutions Linux.
BitLocker Drive Encryption completely
BitLocker encryption is a complete solution for driving the first debuted in Windows Vista as a means to protect data stored on easily lost or stolen laptops executive. TPM 1.2 hardware is required to store encryption keys and can be configured through Group Policy.
On the server, BitLocker is particularly useful for machines stored in branches, because these servers are often less physically protected and machinery back to the home office. If a thief walks away with a secure server BitLocker, which can not access all data stored on disks drives in the system. BitLocker also works very well with some of the other technologies discussed here to create an industry solution truly secure and useful. (See below for an example RODC).
Read-Only Domain Controller
Read-Only Domain Controller (RODC) is a new feature that allows administrators to configure any database in read-only AD, in which only the user passwords are stored locally cached in the machine and AD replication is unidirectional, rather than as bidirectional.

So why do that? Today, many organizations are installing servers in branch offices and other remote areas, and these servers often connected to the central office by slow WAN links or unreliable. This makes AD replication itself and the authentication of a long and arduous process. With RODC, the server is usually installed and configured on the Home Office sent to the remote location, then energized. Therefore, only the user names and passwords of users who hit the local server, not the administrator account is cached locally on the server.
As BitLocker, RODC is an excellent server solution for remote physical insecurity. In fact, when combined with other Windows Server 2008 RODC new technologies such as BitLocker and Core Server, can set the distance as safe as possible. Thus, even hackers to gain physical control of the server can not have on your network. And eliminate the theft of your ad RODC is as simple as making a switch: Only users who have logged into this computer will have to change their passwords. You do not have to create an organization scale emergency, as most user accounts are not cached on the computer.
RODC is a somewhat limited because it can only offer a subset of the features and functionality normally supported on Windows Server 2008. For example, RODC database servers can support technologies such as ADFS, DHCP, DNS, Group Policy (GP), DFS, MOM (Microsoft Operations Manager) and SMS (System Management Server).
7, Internet Information Services
The new web server on Windows Server 2008 is controlled by a major upgrade to the new Internet Information Server Services (IIS). From the server, IIS 7 is completely on components so that only the necessary components to the desired settings are installed and, therefore, need to be repaired. It sports a much improved management console supports the deployment of Web applications xcopy and the delegated administration, and is supported by a new one. NET store configuration, which replaces the previous Warehouse monolithic configuration.
Terminal Services
Terminal Services Server (TS) have been major changes in Windows Server 2008. TS RemoteApp The new feature allows administrators to remotely deploy individual applications rather than desktop PC environments completely, which can be confusing to users. Download and run these applications on users' computers and, apart from the junction box initial dialogue, the role and looks almost exactly like that have been installed locally. This feature requires the new Remote Desktop client, which is included in Windows Vista and can be downloaded for Windows XP with Service Pack 2 and later.
TS TS Gateway allows HTTPS tunnel sessions outside the corporate firewall, so that users can access their applications remotely on the road without having to configure a VPN client. This is particularly useful because VPN connections are blocked to wireless access points, while HTTPS is rare.
TS gets a few changes, but equally useful. These include TS Easy Print, which provides local printing to remote sessions, support 32-bit color in TS sessions, and easily copy and paste operations between the host operating system and remote sessions.
Network Access Protection
Microsoft had originally planned to send network functionality simple quarantine and easily configured in Windows Server 2003, but is finally here with Network Access Protection (NAP). This feature allows security policies your network configuration: When a client connects, the PAN examine the appliance to ensure it meets the requirements of security policies. Those who are allowed in line. Those who are not, in general, the machines are rarely connected to the network, such as those used by employees traveling reserve a portion of the network quarantine, which can be updated. How will these changes affect the configuration depends on your environment, but once that is completed, the system is full access and allowed back again on the network. NAP includes sanitation failback Windows Update or Microsoft Update if the local Windows Server Update Services server is not available, and compatibility with the Cisco Network Admission Command (NAC) technologies quarantine.
Windows Firewall
For the first time Windows Server comes with a Firewall is enabled by default. The new Windows Firewall is bidirectional and works perfectly with all functions and features you can configure in Windows Server 2008. In fact, the firewall is part of the management model based on new functions: How to activate and deactivate the various roles and functions Windows Firewall is configured automatically in the background so that only the necessary ports are open. This is a major change, which could hinder compatibility with third-party products for testing will be crucial.
command line and scripting goodness
Those who prefer to automate their servers will welcome the command line and scripting new enhancements in Windows Server 2008, if I am a little worried the opportunity and the temporary nature of some of these changes. In this version of Windows Server, see the beginning of the transition from the DOS command line, as old to new. NET PowerShell environment. For now, however, must have a foot in both environments to maximize the new features. Server Core for example, is not compatible with PowerShell.
One side of the command line, we added two major elements: A management utility called Server Core oclist.exe and a command line version called Server Manager ServerManagerCmd.exe. Both are designed with the same premise, offering ways to configure and manage the functions that are possible in all environments.
PowerShell is a complex, but technically impressive, with the support of discovery. NET the properties and methods. It provides all the power of UNIX command line without inconsistencies. The question, of course, is whether Windows manages to move quickly the new command from the CLI. Unfortunately, Windows Server 2008 does not help much: it does not come with scripts fully PowerShell commands can be executed content from the command line that can handle the current management tasks. Microsoft says it is available in Windows Server 2008 commandlets on its website through time however, and expects a healthy community to change rapidly.
Hyper-V
One of the most important technologies and forward future in Windows Server 2008 is not yet available in the original product shipment. Instead, Microsoft is selling a beta version of its virtualization platform Hyper-V in Windows Server 2008 and automatically updated when the technology is completed shortly after mid-2008. Hyper-V is a hypervisor virtualization based on a platform that has performance advantages over multiple platforms, application-level virtualization and Virtual Server. Compared with market leader VMWare Microsoft offers an immature and unproven, but their inclusion in Windows Server 2008 is sure to get attention on some part of Microsoft and markets. And there are advantages to this group: a management perspective, Hyper-V installed and managed as a role in Windows 2008, DHCP, file and print services and a standard feature. This means it is easy to configure, manage and maintain.
Hyper-V only comes with the x64 versions of the product and is based on hardware virtualization features that are only available in the latest AMD and Intel chipsets. It is compatible with 32 bits evaluation systems and 64-bit operating up to 32 GB of RAM in each guest operating system and up to four processor cores to each guest operating system. Hyper-V supports virtual machines created for Microsoft virtualization products before, like Virtual PC and Virtual Server.
