Terminal Services licensing
There are a lot of problems with Microsoft terminal services and most of them are due to a lack of knowlage about licensing terminal services. Licensing is actually the number one issue when deploying farms with terminal services or Citrix. Keep also in mind that Citrix Presentation server is just an Add-on
for Microsoft terminal services and does NOT include any Microsoft license, ONLY
Citrix Access Essentials has TSCAL's included.
Make sure you know the basics with licensing terminal services: NOTE
- You do not have to purchase a Windows Server Terminal Services Client Access license to connect to a server that is running Windows Server Terminal Services. However, you must still deploy and activate a server that is running Terminal Services Licensing.
- For Windows Server 2003, you receive a maximum of 210 days for evaluation (a grace period of 120 days plus a temporary token of 90 days). For Microsoft Windows 2000, you receive maximum of 180 days for evaluation (a grace period of 90 days plus a temporary token of 90 days).
- You have to run a Windows 2003 licensing Server when using Windows 2003 Servers acting as terminalserver.
- Microsoft's desktop os products incl. Windows XP Professional. or Windows 2000 Professional do NOT have a "built-in" Terminal Services CAL. Rather, the Windows 2000 server issues machines running Windows 2000 Professional or Windows XP Professional with a "free" TSCAL from its built-in pool.
- Windows XP Professional is a successor to Windows 2000 Professional, and as a result does NOT need a TSCAL to access a Windows 2000 Server running Terminal Services. Windows XP Home Edition is NOT a successor to Windows 2000 Professional and therefore does require a TSCAL in order to access Windows 2000 Terminal Services.
- Required licenses to run only Terminal Services in application mode
- Windows 2000 Server license
- A Windows 2000 or BackOffice CAL
- Windows 2000 Terminal Services CAL
- Especially with Windows XP, make sure user have write access on the workstation registry hive:
