Thanks David & Rick  for the reply.

I have better understanding of WTS licensing after reading below:
http://www.microsoft.com/windowsserver2003/howtobuy/licensing/ts2003.mspx

The observation I made was due to miss-configuration in our testing system. Sorry about that.

On a related note, there's also something called "server affinity", which is a kind of load-balancing override for license conservation as you suggest.

The way this works is, say for example you have some licensed application installed on two different servers. When the user starts their first copy of this application, a server is selected according to whatever load-balancing property you may have set. When the second instance is started, since this user has already started a copy of the application, this second instance will be started on the same server as the first. This is called server affinity, and is designed to prevent a user from consuming excess application licenses. IIRC, this originally had Microsoft Office CAL's in mind, but since Office is licensed per client device, I don't really think this applies, at least not anymore. See: http://docs.sun.com/source/820-1088/t3loadbal_config.html#affinity

(Whenever I discuss Microsoft licensing, I promptly get a visit from a large, hairy "lawyer" who reminds me that I really shouldn't speak about Microsoft licensing policies, and reinforces that with a very hard kick to a very soft place. So, anything I say about Microsoft licensing is probably wrong. Actually, anything I say here is probably wrong, so take it all with a grain of salt. )

As for TSCALs, what David wrote is correct - I'll just add that the location of your issued license is your local registry (for a Windows-based computer) or the SGD server itself for non-Windows clients (see: http://docs.sun.com/source/820-1088/tta_tscal.html), with the source of the license your local license server..

Rick

SGD does open a separate RDP session for each application. However, multiple applications from the same user/device (depending on how WTS is licensed) should consume one TS CAL only. Are you seeing evidence that multiple TS CALs being consumed from multiple applications launched by the same user/device?

Sorry for not explaining my question clearly.

When we create Windows applications (e.g. Word, Excel, Powerpoint, etc) on SGD, each of these Windows applications consumes 1 Microsoft client access license (CAL) upon call up. When there are more Windows applications to be published through SGD, the number of MS CAL increases.

I like to know if there is way on SGD to make use of an established Windows session to call up other applications that reside on the same server host. Be it a simple configuration or customization to SGD itself.

Thank you.

I notice that each Windows application establishes one client session to a Windows server when open and hence uses up one terminal service license.

Is there setting in SGD such that multiple Windows applications can share the same Windows user session?

Thank you.
