    "The Remote Desktop license server "SERVERNAME" does not have any remaining permanent Remote Desktop Services client access licenses (RDS CALs) of the type "Windows Server 2008 or Windows Server 2008 R2 : Per Device CAL (TS, RDS or VDI)". As a result, the Remote Desktop license server cannot issue RDS CALs of the type "Windows Server 2008 or Windows Server 2008 R2 : Per Device CAL (TS, RDS or VDI)" to the Remote Desktop Session Host server "10.181.1.124". 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.

  • Hi, this is completely normal.

    Here is the explanation. When you install Windows 2008 License server I guess you installed only Windows 2008 RDS CAL's. So when users connect to Windows 2003 TS Servers it request the W2008 server for 2003 RDS CAL if it cant have any the License server give out licenses which are a level higher. In your case W2008 RDS CAL. That is what produces the message. It is behaviour as expected.

    There is a group policy which controls that:

    http://technet.microsoft.com/en-us/library/ee791761(WS.10).aspx

    Prevent license upgrade

    This policy setting allows you to specify which version of Remote Desktop Services client access license (RDS CAL) a Remote Desktop Services license server will issue to clients connecting to RD Session Host servers running other Windows-based operating systems.

    A license server attempts to provide the most appropriate RDS CAL for a connection. For example, a Windows Server 2008 license server will try to issue a Windows Server 2008 TS CAL for clients connecting to an RD Session Host server running Windows Server 2008, and will try to issue a Windows Server 2003 TS CAL for clients connecting to a terminal server running Windows Server 2003.

    By default, if the most appropriate RDS CAL is not available for a connection, a Windows Server 2008 license server will issue a Windows Server 2008 TS CAL, if available, to the following:

    • A client connecting to a Windows Server 2003 terminal server
    • A client connecting to a Windows 2000 terminal server

    If you enable this policy setting, the license server will only issue a temporary RDS CAL to the client if an appropriate RDS CAL for the RD Session Host server is not available. If the client has already been issued a temporary RDS CAL and the temporary RDS CAL has expired, the client will not be able to connect to the RD Session Host server unless the RD Licensing grace period for the RD Session Host server has not expired.

    If you disable or do not configure this policy setting, the license server will exhibit the default behavior noted earlier.
