Microsoft terminal server

Hello...

We have to migrate one of our applications to the MS terminal server.
The problem is, one instance of our application starts 4 processes using
BDE.

According to TI2751 you can have 48 clients per system, 12288 sessions
per system etc.

The question is : What IS a system/client ?

    One machine ? One User connection ?

ANY reasonable answers appreciated.....

Qapla'
