The RDS Server Sessions service, formerly Windows Terminal Server, monitors the availability of the port, which the clients of the Microsoft Terminal Services use to connect to the Terminal Services application. The availability of the port, which is determined by the service testing the port's connectivity, indicates that the Terminal Services are able to connect to the Terminal Services application. This service also measures the DNS resolution and the round trip time of the initial connection request and response. The availability results of the TCP service are then reflected on the status dashboard for the Windows Terminal Server service.
You can set a maximum of three instances of this service a device, with each instance monitoring a different port on the device.
The service does not use the Warning state.

If an FQDN has been specified, the service searches for its IP address. If the IP address is found, the state will be Normal. Otherwise, it will be Failed, based on the default settings.
If an IP address has been specified, the service checks only the IP address's format. If the format is correct, the state will be Normal. Otherwise, it will be Failed, based on the default settings.
