You can only revoke an RDS Per Device CAL. You can revoke an RDS Per Device CAL by using the Remote Desktop Licensing Manager tool. For example, you might want to do this if the client computer or device is no longer a part of your environment.
WINDOWS SERVER 2012 REMOTE DESKTOP SERVICES DEVICE CAL LICENSE
In some circumstances, you might want or need to return an RDS Per Device CAL that has been issued back to the available pool on the license server before the automatic expiration period has been reached. The temporary license is valid for 90 days.Ī permanent RDS Per Device CAL issued by a license server is configured to automatically expire after a random period between 52 and 89 days, at which time the RDS Per Device CAL returns to the pool of available RDS Per Device CALs on the license server. If the license server is not activated or does not have any RDS Per Device CALs available, the device continues to use the temporary license. When a client computer or device connects to an RD Session Host server for the second time, if the Remote Desktop license server is activated and enough RDS Per Device CALs are available, the license server issues the client computer or device a permanent RDS Per Device CAL. When a Remote Desktop Session Host (RD Session Host) server is configured to use Per Device licensing mode, and a client computer or device connects to an RD Session Host server for the first time, the client computer or device is issued a temporary license by default.
