Windows Server 2008 R2 became available in the summer of 2009. In many ways, it is just the next-generation server operating system update to Windows Server 2008, but in other ways, it is more than just a service pack type update with significant feature enhancements introduced in the version release. To the authors of this book, we see the similarities that Windows Server 2008 R2 has in terms of usability and common graphical user interfaces (GUIs) with previous versions of Windows Server that make it easy to jump in and start implementing the new technologies. However, after over two years of early adopter experience with Windows Server 2008 R2 and the Windows 7 client operating system, when properly implemented, the new features and technologies built in to Windows Server 2008 R2 really address shortcomings of previous versions of Windows Server and truly allow IT organizations to help organizations meet their business initiatives through the implementation of key technologies now included in Windows Server 2008 R2.
One of the new embedded technologies in Windows Server 2008 and Windows Server 2008 R2 is self-healing NTFS. Effectively, the operating system has a worker thread that runs in the background, which makes corrections to the file system when NTFS detects a corrupt file or directory. In the past when there was a file system problem, you typically had to reboot the server for chkdsk to run and clean up file and directory corrupt errors.

For SMB2 to work effectively, the systems on both ends need to be Windows Server 2008/2008 R2 systems, Windows Vista or Windows 7 systems, or a combination of the two. A Windows XP client to a Windows Server 2008/2008 R2 server will communicate over SMB 1.0 for backward compatibility and will not gain from this new technology.
Hyper-V is a technology built in to the core of the operating system in Windows Server 2008 and expanded in Windows Server 2008 R2 that greatly enhances the performance and capabilities of server virtualization in a Windows environment. In the past, virtual server software sat on top of the network operating system and each guest session was dependent on many shared components of the operating system.
A technology enhanced in the core Windows Server 2008 R2 operating system is a power-management technology called core parking. Normally, when a multicore server runs, all cores on all processors run at the highest speed possible, regardless of whether the server is being utilized. For organizations that need high capacity during the weekdays when employees are working, that means their systems are effectively idle during evenings and weekends, or more than two thirds of the time, yet consuming power and expending heat. With core parking, servers with the latest processors that recognize core parking protocols will shut down cores on a system when not in use. So, on a 16-core server, if only 2 cores are needed, the other 14 cores are powered off automatically. This dramatically improves power management and decreases the cost of operations of server systems.
As much as there have been significant improvements in Windows Server 2008 R2 under the hood that greatly enhance the performance, reliability, and scalability of Windows Server 2008 R2 in the enterprise, Windows servers have always been exceptional application servers hosting critical business applications for organizations. Windows Server 2008 R2 continues the tradition of the operating system being an application server with common server roles being included in the operating system. When installing Windows Server 2008 R2, the Server Manager Add Roles Wizard provides a list of server roles that can be added to a system, as shown in Figure 1.2.
Although Windows Server 2008 R2 provides a number of new server roles for application services, the release of Windows Server 2008 R2 also brings with it an update to Active Directory. Unlike the shift from Windows NT to Active Directory a decade ago that required a major restructuring of domain functions, Active Directory 2008 R2 is more evolutionary than revolutionary. AD 2008 R2 adds a handful of new features that organizations might or might not choose to upgrade to AD 2008 R2 immediately; however, many organizations have found that the new enhancements in Active Directory 2008 R2 were the primary reason for their migration.
SQL Server 2008/R2 and Windows Server 2008/R2 Extended Security Updates (ESUs) will end support on July 12, 2022, and January 10, 2023, respectively. Customers who require additional time to upgrade may rehost their servers on Azure to receive one additional year of free ESUs.
You can install Windows Admin Center on Windows Server 2019 and Windows 10 and earlier versions of Windows and Windows Server, and use it to manage servers and clusters running Windows Server 2008 R2 and later.
Transport Server contains only the core networking parts of WDS. You can now use Server Core with the Transport Server role to create multicast namespaces that transmit data (including operating system images) from a standalone server. You can also use it if you want to have a PXE server that allows clients to PXE boot and download your own custom setup application.
Containerizing Windows-based applications just got easier: The app compatibility for the existing windowsservercore image has been increased. For applications with more API dependencies, there's now a third base image: windows. 2ff7e9595c
