As a rule of thumb, you can use the following procedure to determine a limit for the amount of memory per session:
- Start a Terminal Server without any user sessions.
- Make a note of the amount of available memory (this is the amount of installed RAM, minus the overhead used by the OS).
- Divide the amount of available memory by the number of users who are to use this server.
The resulting number is the amount of memory that you can set per session.
