It is recommended that you install your Remote Desktop Session Host on a computer that is not a domain controller. Make sure that you back up the terminal server licenses regularly, so as not to lose data.

iFIX Remote Desktop Clients
When a Windows Server client connects to the Remote Desktop Session Host with External Connector Licensing disabled, the license from the client is used. The first time that you connect to the Server, that license is activated.
External Connector Licensing was formerly known as Internet Connector Licensing. External Connector Licensing is not supported with iFIX. By default, External Connector Licensing is disabled on the Remote Desktop Session Host.
If you are running a non-Windows Server 2012 client computer, you need to purchase Windows Remote Desktop Services Client Access Licenses (TSCALs) from Microsoft. When you first set up the iFIX with Remote Desktop Services, you have a 120 day temporary license to run a maximum of 10 client machines from the Server. The first 10 Windows 9x and NT client machines that connect to the Server will reserve the licenses.
NOTE: Remote Desktop Services Client Access Licenses (TSCALs) are counted per device and are not concurrent.
WARNING: Once you activate a TSCAL, it is permanently associated with that machine. You cannot reboot the machine to clear your license use. If you reformat the machine, you must contact Microsoft to obtain a replacement license.
iClientTS Licensing and Keys
An iClientTS Hardware Key is required on the Remote Desktop Session Host computer to enable iFIX to run in Remote Desktop Session Host mode. No hardware keys are required on the thin client machines.
If you purchased iClientTS, you are responsible for ensuring that your licenses are used correctly. Using Remote Desktop Services capability, you can limit the number of incoming client connections to the number of iClientTS licenses that you have purchased. You can also use Remote Desktop Security and iFIX Security to limit the users who can initiate iClientTS sessions on the Remote Desktop Session Host.
If you have iClientTS licenses that enable a mixed environment of Developer, Run Time, and Read-Only users, your Hardware Key will be enabled for Developer use. To limit users to:
Run Time only – Implement iFIX security and authorize only the ability to use the WorkSpace Run-Time application.
Read-only – Select a single security area and apply this security area to all tags. Configure iFIX security so that read-only users are not authorized for this security area.
You can also limit your users to Read-Only capability by providing a user environment that does not provide any opportunity to change values. For example, you could use Data Entry Type = None for all data links when creating displays. Or when using Alarm Summaries, clear all of the items on the Operator tab in the Alarm Summary Configuration dialog box.
If you have iClientTS licenses that enable a mixed environment of Run Time and Read-Only uses, your Hardware Key will be enabled for Run Time use. To limit users to Read-Only, use the methods described above.
For more information on setting up your licensing system and iFIX Security, refer to the Configuring Security Features manual.
