With Terminal Services in Windows Server 2008, organizations can provide
more secure access to centralized applications or desktops (and other resources
from the Internet) by using HTTPS—without needing to provide access via a
Virtual Private Network (VPN) or opening up unwanted ports on firewalls. This
reduces the complexity needed to provide secure remote access to applications
and data for users, partners, or customers. And for deployments with several
servers, new load-balancing features provide a simple way to ensure optimal
performance by spreading sessions among the least-loaded available resources.
These Terminal Server Device CALs permits 5 devices (used by any users) to
conduct Windows Sessions on any of your servers.
