Licensing with 3 Servers


David Hellewell

Current Situation -
SBS2K Server
W2K Server used as TS
Workstations XP Pro
No Need for TS License

I now need to add a W2003 Server as a Terminal Server And realise that I
need to buy TS Licenses.

Are these new TS 2003 licenses installed on the SBS2000 as this is the
Domain controller? If so how will this effect the W2000 Terminal Server as
the users need to be able to RDP into both the Terminal Servers?

No, you cannot install 2003 TS CALs on the SBS2000 server, since
it doesn't understand the new license types (Per user versus Per

So you must install and activate the TS Licensing Service on your
2003 member server. That is in itself not a problem, since a 2003
LS doesn't have to run on a DC anymore.
You might have to point the 2003 TS to the 2003 LS (itself),

Thanks Vera,

How do I - "You might have to point the 2003 TS to the 2003 LS (itself),

Looking at the MS site it states -
"Windows Server 2003 needs a new version of CALs. You need a Windows Server
2003 License Server, which can serve both Windows 2000 terminal servers and
Windows Server 2003 terminal servers."

Since Windows 2000 terminal servers don't need CALS for XP Pro then how can
this work?

How you can point the 2003 TS to the 2003 Licensing Server is
described in the KB article I referenced (279561). (context of the
thread gone because your newsreader put in a "--" before your
signature, but check my first post).

About your W2K Pro and XP Pro clients: they also need (and have
received) a TS CAL when they connect to a W2K TS, but the
difference is that they receive such a W2K TS CAL for free from the
built-in pool of "Existing Windows 2000 Per Device TS CALs" on the
Licensing Server, *when they connect to a W2K TS*.

As soon as they connect to a 2003 TS, they need a purchased 2003 TS

A 2003 Licensing Server can handle both W2K and 2003 TS CAL, and it
can also issued these "free" W2K TS CALs. So you can choose to
either deactivate your old TS Licensing Server from the SBS2000
server and have the new 2003 LS handle all licenses, or you can
continue to let the SBS2000 server take care of the W2K TS CALs and
have the 2003 LS handle only the 2003 TS CALs. I would prefer the
first scenario, though.

All this, and more, is described in the White Paper.
