What’s New in Windows Server R2
Hi to all here i write some networking basics of Windows Server 2008. Thanks to Microsoft team.
What Is R2?
Windows Server 2008 R2, or simply “R2” for short, is the second release of Windows
Server 2008. It isn’t a completely new release, but rather adds additional features and
refinements to the existing release.

Server 2008. It isn’t a completely new release, but rather adds additional features and

Release Cadence
Beginning with Windows Server 2003, Microsoft moved to a server release cycle that
was designed to have a major release every three to five years (Windows Server 2003,
Windows Server 2008), with a minor release at the approximate midpoint of the major
release cycle (Windows Server 2003 R2, Windows Server 2008 R2). This change allowed
Microsoft to move away from including new functionality in service packs (SPs), while
providing customers with a more stable and predictable server environment.
An R2 release is more than an SP, but less than a full major release. Windows Server
2008 R2 includes Windows Server 2008 SP2, but it also adds many new features and
functionality that were not part of Windows Server 2008.

Licensing and Packaging Changes
There are some minor licensing changes included in Windows Server 2008 R2, and one
completely new edition since the original release of Windows Server 2008. The new edition is
Windows Server 2008 R2 Foundation, an original equipment manufacturer (OEM)–only edition
that is an entry-level small-business solution limited to a maximum of 15 users, which has
several other restrictions as well.

The licensing of Windows Server 2008 R2 is very similar to that of Windows Server 2008,
and you can use Windows Server 2008 Client Access Licenses (CALs) for Windows Server 2008
R2 without having to upgrade your license. There is, however, one important difference that
is introduced with Windows Server 2008 R2—there is no requirement to upgrade to Windows
Server 2008 CALs when you install Windows Server 2008 R2 on a physical server that is only
used with the Hyper-V role.
Another difference between Windows Server 2008 and Windows Server 2008 R2 licensing
is caused by the name change from Terminal Services (TS) in Windows Server 2008 to Remote
Desktop Services (RDS) in Windows Server 2008 R2. This is more than just a name change,
and we cover the new features and functionality in depth in Chapter 4, “Remote Desktop Services
and VDI: Centralizing Desktop and Application Management.” However, for the licensing,
it really is just a name change—Windows Server 2008 R2 RDS CALs and Windows Server
2008 TS CALs can both be used for the full functionality of Windows Server 2008 R2 RDS.
There are also new license suite options in Windows Server 2008 R2, with the introduction
of the new Virtual Desktop Infrastructure (VDI) Standard and Virtual Desktop Infrastructure
Premium suites. We cover these new suite licenses in Chapter 4 when we talk about the new
VDI functionality that R2 makes possible.

The Focus for R2
It would be presumptuous of us to talk about the “vision” that Microsoft had for Windows
Server 2008 R2, but we can certainly see a pattern in where the major improvements are:
1. Virtualization
2. Management
3. Scalability
4. Web

5. Networking and access
6. “Better Together” with Windows 7

We take a look at each of these areas throughout this book, but let’s start with a quick
high-level look at what has changed in each area.

Virtualization
Direct support for server virtualization, in the form of the Hyper-V hypervisor, was one of the
most important and highly anticipated improvements in Windows Server 2008. With the release
of Windows Server 2008 R2, Microsoft extends Hyper-V virtualization to include support
for client desktop virtualization, and adds important new capabilities for dynamic disk allocation,
live migration, and improved scalability and redundancy. We cover the improvements in
Hyper-V server virtualization capabilities in Chapter 3, “Hyper-V: Scaling and Migrating Virtual
Machines.”
Virtualization, however, isn’t limited to machine virtualization, but also includes presentation
virtualization (RDS), application virtualization (App-V), and client desktop virtualization
(VDI).
Windows Server 2008 R2 adds improvements in RDS that provide a more seamless integration
with Windows 7 clients, including full support for Windows Aero and multiple monitors.
Application virtualization support in R2 is improved, and the addition of the Remote Desktop
Virtualization Host (RD Virtualization Host) role service enables full desktop virtualization. We
cover VDI and RDS in greater detail in Chapter 4.
