Windows Server 2008 R2 is a server operating system produced by Microsoft. It was released to manufacturing (RTM) on July 22, 2009 and launched on October 22, 2009. According to the Windows Server Team blog, the retail availability was September 14, 2009. It is built on Windows NT 6.1, the same kernel used with the client-oriented Windows 7. It is the first 64-bit-only operating system released from Microsoft. Version enhancements include new functionality for Active Directory, new virtualization and management features, version 7.5 of Microsoft IIS Web Server and support for up to 256 logical processors.

Windows Server is a brand name for a group of server operating systems released by Microsoft. It includes all Windows operating systems that have “Windows Server” in their names: Windows Server 2003, Windows Server 2003 R2, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016 (upcoming) but not any other Microsoft product. The first Windows server edition to be released with that brand was Windows Server 2003. However, the first server edition of Windows was Windows NT 3.1 Advanced Server, followed by Windows NT 3.5 Server, Windows NT 4.0 Server, and Windows 2000 Server; the latter was the first server edition to feature many things like Active Directory, DNS Server, DHCP Server, Group Policy, and many other popular features used today.
Windows Server 2008 R2, was available in twelve different editions: Windows Server 2008 R2 Foundation, Windows Server 2008 R2 Standard, Windows Server 2008 R2 Enterprise, Windows Server 2008 R2 Datacenter, Windows Server 2008 R2 for Itanium-based Systems, Windows Web Server 2008 R2, Windows Storage Server 2008 R2, Windows HPC Server 2008 R2, Windows Small Business Server 2011, Windows MultiPoint Server 2011, Windows Home Server 2011 and Windows MultiPoint Server 2010.
Windows Server 2008 R2 builds on the award-winning foundation of Windows Server 2008, expanding existing technology and adding new features to enable organizations to increase the reliability and flexibility of their server infrastructures.
Windows Server 2008 R2 Features
- Hyper-V Live Migration
- Moves virtual machines between two hosts without interruption (slight performance drop)
- Uses the new Cluster Shared Volumes (CSV) file system within Failover Clustering in Windows Server 2008 R2
- CSV volumes can only be used for the Live Migration feature
- Requires failover clustering of Windows Server 2008 R2
- Cluster Node Connectivity Fault Tolerance
The CSV architecture supports dynamic I/O redirection (I/O can be rerouted within the failover cluster) for three types of failures:
- Failure of a cluster node connection to the shared storage between cluster nodes
- Failure of network connectivity for a cluster node
- Failure of a cluster node
- Other Hyper-V 2.0 features
- Support for 32 logical processor cores in a single virtual machine
- Hot add of VHD and pass-through disks
- Second Level Translation (SLAT): Support for Intel’s Enhanced Page Tables and AMD’s Nested Page Tables (improves performance, especially for large applications, due to better memory management; it also reduces the memory requirements for the Windows Hypervisor from approximately 5% to 1% of the total physical memory)
- Boot physical machines from .vhd files: Allows you to deploy Windows Server 2008 R2 to physical and virtual computers using the same .vhd files
- Virtual Desktop Infrastructure (VDI)
Desktop Virtualization is a new feature in Windows Server 2008 R2. I will write more about this topic soon.
- Windows clients (XP, Vista, Windows 7) run on virtual machines on a centralized server
- VDI includes the following technologies: Hyper-V, Live Migration, System Center Virtual Machine Manager 2008, Microsoft Application Virtualization version 4.5 in Microsoft Desktop Optimization Pack (MDOP), and Vista Enterprise VECD licensing
- RemoteApp & Desktop Connections (RAD)
RemoteApp was introduced with Windows Server 2008. It allows end-users to launch a single application on a remote server via RDP. Desktop Connections are common sessions on a Terminal Server.
- RAD control panel applet: Allows end-users to connect to RemoteApp programs and Remote Desktops
- Single management console for RemoteApp, Desktop Web Access, and Remote Desktop
- RemoteApp and Remote Desktop also work for standalone computers (non-domain members)
- New apps are automatically populated to users’ desktops and Web Access page
- Single sign-on (I guess only for domain members)
- Almost all Remote Desktop Services administrative tasks can now be scripted using PowerShell 2.0
- Profile cache quota and Group Policy caching speed up user logon
- Improved compatibility with Microsoft Installer (MSI); no need for “install mode” where users had to log off
- Remote Desktop Services Gateway (formerly Terminal Services Gateway) (improved)
- Silent Session Re-authentication: Ensures that changes to user profiles are enforced
- Secure device redirection: Device redirection settings are always enforced
- Pluggable Authentication: Allows corporations to use their own authentication and authorization technologies
- Idle & session timeout: Allows admins to disconnect idle sessions or limit the connection time
- Consent Signing support: Remote users have to give their consent to corporate terms and conditions
- Administrative messaging: Broadcast messages to remote users
- RAD enhancements for third parties
- Support for Cascading Style Sheets (CSS) and XSL Tranformations (XSLT) to customize the Web Access portal
- Support for protocols other than RDP
- Session broker extensibility: Policy (determines the proper farm or VM for a connection), Load Balancing (chooses the proper endpoint based on load), Orchestration (prepares a VM to accept RDP connections)
