Windows Server 2003 Terminal Server may not always get CALs from a Windows Server 2012 license server

View products that this article applies to.

Symptoms

Assume that you are using Windows Server 2003 Terminal Server, and that you have configured it to use a license server installed on Windows Server 2012 or a later version. In this situation, you may notice that the Per Device client access licenses (CALs) used by the Remote Desktop Protocol (RDP) clients are always temporary, and that no permanent licenses are issued for these Windows Server 2003 Terminal Services (TS) clients.

To verify this issue, open Remote Desktop Licensing Manager and check the issued licenses. If you have installed Windows Server 2003 Per Device CALs, you notice that none of them may be issued. If you have installed only Windows Server 2008 or Windows Server 2012 CALs, you notice that no CALs may be downgraded to be issued by Windows Server 2003.

Cause

This issue occurs when the license server was activated by using the online method, or when the license server was activated by using an offline method (a web browser or the telephone) while the CALs were installed by using the online method. In these cases, certificates that are used by the license server are signed by using the SHA2 hashing algorithm, and this algorithm is not recognized by Windows Server 2003.

Resolution

To resolve this issue, activate or reactivate your license server by using an offline method. If it was already activated by using an offline method, then install the CALs by using an offline method.
