The Remote Desktop license server "%1" does not have any remaining permanent Remote Desktop Services client access licenses (RDS CALs) of the type "%2". As a result, the Remote Desktop license server cannot issue RDS CALs of the type "%2" to the Remote Desktop Session Host server "%3". To resolve this problem, verify that the Remote Desktop licensing mode configured on the RD Session Host server matches the type of RDS CALs installed on the Remote Desktop license server. If required, purchase and install additional RDS CALs as needed for this Remote Desktop license server.
