Farm Controller and Application Servers have the standard Terminal Service Plus requirements for hardware.
Farm Controller and Application Servers must use one of the following Operating System:
32 and 64 bits platforms are supported.
Every Application Server must be accessible from the Farm Controller.
More specifically, the Farm Controller will issue requests to every Application Server on its API port (19955 by default) and this port must be opened on any firewall standing between the Farm Controller and Application Servers.
The network latency must be low between the Farm Controller and Application Servers. A latency under 200 ms is recommended, a latency under 2 000 ms is required.
.NET 2.0 or higher is required - this should not be a problem as a compatible .NET version is enabled by default on every Operating System supported for Terminal Service Plus Farm.
Terminal Service Plus must be in "Enterprise" edition on the Farm Controller and on all the Application Servers.
All the servers must also run the same version of Terminal Service Plus.
Farm Controller and Application Servers must have the same date/time configured. It is highly recommended to synchronize the Windows clock of all servers with an Internet Time Server if not already done.
An Active Directory is not required, however if you do have an Active Directory, then your Domain Administrators must also be Local Administrators of the Farm Controller to be able to use Terminal Service Plus Farm Manager.
