An RD License server will always attempt to issue the most appropriate
version of RDS CAL to an RD Session Host server that requests it on behalf
of a connecting client. For example, if you have a license server with both
Windows Server 2003 CALs and Windows Server 2008 R2 RDS CALs installed, and
a client connects to a Windows Server 2003 terminal server, the RD Licensing
server will attempt to issue a Windows Server 2003 CAL. But if the license
server runs out of Windows Server 2003 CALs, it will issue an available RDS
CAL instead. This is because RDS CALs can be used with the version of
Windows for which they were made, as well as for any previous version back
to Windows 2000.
FWIWby default 2008 licence server has an unlimited pool of 2000 cals
*Because you haven’t yet installed any RDS CALs on the license server, you
may wonder why the license server contains a reference to Windows 2000.
That’s the result of a decision made in the Windows 2000 era. At that time,
any Windows 2000 Professional computer had a license to access a Windows
2000 Server terminal server. Many people referred to this as a "built-in"
license, but this is misleading. There was no license built into Windows
Server 2000 Professional, just the ability to pull from the Unlimited pool
on the license server.
Beginning with Windows XP and Windows Server 2003, no client operating
system has been able to draw from this Unlimited pool, but it’s still
available if you have (a) Windows 2000 Server terminal servers using the
license server and (b) Windows Server 2000 Professional clients that will be
using those license servers. If you don’t have both, this Unlimited license
pool is totally irrelevant. Even if you have Windows 2000 Professional
clients, they cannot draw from the Unlimited pool to access a Windows Server
2008 RD Session Host server or a Windows Server 2008 or Windows Server 2003
terminal server
