In Windows Server 2008 R2, Terminal Services client access licenses (TS CALs) are now called Remote Desktop Services client access licenses (RDS CALs). If you also have 200 Windows Server 2008 R2 RDS Per Device CALs installed on the license server, you can revoke up to 40 of those Windows Server 2008 R2 RDS Per Device CALs in addition to the Windows Server 2003 TS Per Device CALs that you have revoked. For example, if there are 100 Windows Server 2003 TS Per Device CALs installed on the license server, you can only have 20 of those Windows Server 2003 TS Per Device CALs revoked at any given time. You can only revoke up to twenty percent of the number of RDS Per Device CALs of a particular version installed on your license server. Revocation is not a substitute for ensuring that you have enough RDS Per Device CALs to support your environment. You cannot revoke an RDS Per User CAL.Īfter you have revoked the RDS Per Device CAL, that RDS Per Device CAL is immediately available to be issued to another client computer or device. 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.

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.
