Windows Server 2012 RDS CALS on Windows Server 2008 R2 Licensing Server

    Question

  • Hi,

    at the moment we are installing the first couple of Windows Server 2012 in our infrastructure.

    Some of them have installed RDS.

    Now we are wondering whether it is possible to use our existing Windows Server 2008 R2 licensing server for serving the licenses we have (yes we to have new Windows Server 2012 RDS CALS) or whether we have to install a new host based on Windows Server 2012.

    We tried to add the new license to the 2008 R2 licensing server, but it is not possible. The licensing manager's error message: "The license code contains invalid characters or not enough characters."

    Is there any other way?

    Thanks and regards
    Matthias

  • Hi,

    Server 2012 RDS requires a Server 2012 RD Licensing server.  A 2012 RD Licensing server will serve 2012/2008 R2/2008/2003 servers, so you may consolidate your RDS CALs onto a Server 2012 RD Licensing server if you would like to.

  • Hi matt_will_fix_it,

    How about Windows 2012 R2 ?

    Will a Windows 2012 RD Licensing server provide licences to a Windows 2012 R2 server?

    I have not tested it, but it should work.  Server 2012 R2 requires the same RDS CAL version as Server 2012.  If you try it and have an issue please reply back.

  • We tested it and I can confirm a Windows 2012 RDS Licence server can allocate CALS to a Windows 2012 R2 server.

    Thanks!

  • I have a similar question, I have a 2008 R2 we are trying to setup with RDP, installed roles and attempting to activate server but it will not take the cal license number. We purchased 2012 RDP cals because we read that they were backwards compatible with 2008. Please advise.

  • Hi,

    I confirm that with your 2012 RDS CALs you can downgrade/activate there on the 2008/2008 R2 Server. however, for doing that you need to contcat the Microsoft product Activation for Terminal Server (TSLM) departement in your Region.

    thanks
