Where can I find information on TS server licensing?
By default, when the Per Device licensing mode is used, after a client logs and authenticates to a terminal server for the first time, and after the terminal server locates a license server, the terminal server issues the client a temporary license.
After a client logs on and authenticates to a terminal server for the second time, if the license server is activated and at least one Per Device CAL is installed on the license server and not yet issued, the terminal server issues the client a permanent, Per Device CAL. Per User CALs are not monitored by Terminal Server.
This means that even though there is a Per User CAL in the license server database, the Per User CAL is not decremented when it is used. Additionally, if you use the Per User licensing mode, when a client logs on to a terminal server for the second time, the temporary license is not upgraded to a permanent CAL.
