I bought a server hardware with a Windows Server 2012 R2 Foundation license. That license comes with 15 users, which is sufficient for my needs. I'd like to use the server for RemoteApps. I configured everything and it works fine, but RD Licensing Diagnostics says I have no licenses. On the other hand, RD Licensing Manager reports I have an unlimited number of device TS-CALs of Windows 2000 Server type.
Do I need to buy additional device or user CALs if I want to stay below the 15 user limit?
