Windows Server 2008 also continues to support Itanium-based systems. Since this is
a highly specialized build of Windows Server 2008, it provides limited support for roles
that are not directly related to the ability of the server to host applications. You should
reserve the use of Windows Server 2008 for Itanium-based systems only for applications
that require the performance and scale-up support that it offers.

When we talk about connectivity to systems beyond our local network, we start
getting into the world of Routing and Remote Access Services (RRAS). The Routing
portion of RRAS provides LAN-to-LAN, LAN-WAN, virtual private networks
(VPNs), and Network Address Translation (NAT) routing services. The Remote Access
portion provides remote connectivity to your LAN through dial-up or VPN access. With
the proliferation of broadband, VPN is gaining greater popularity and can provide faster
and more efficient remote connectivity at a lower cost than dial-up services that typically
require specialized hardware such as modem banks to become useful. RRAS has existed
since Windows NT 4.0, but has steadily evolved into RRAS, now an important part of
Windows Server 2008. The implementation of RRAS that is included with Windows
Server 2008 includes the ability to integrate seamlessly with Network Access Protection
(NAP) to give administrators more granular control over the types of systems allowed to
connect to a network remotely.
