I have an Amazon AWS EC2 instance that I installed in 2010 running Windows Server 2008. At that time I purchased 5 RDS CALs to support this server. I recently upgraded this AWS EC2 instance to run Windows Server 2012 R2 and am now receiving this message:
Remote Desktop licensing mode is not configured.
Remote Desktop Services will stop working in 117 days. On the RD Connection Broker Server, use Server Manager to specify the Remote Desktop licensing mode and the license server.
Can I reuse the 5 RDS CALs from 2010 on this newly upgraded server? If so, how do I enter the license information?
