PC-Duo Host can be configured to allow remote viewing and remote control of one or more simultaneous Remote Desktop Services sessions, as well as the Remote Desktop Services server console. A standard PC-Duo Host with a special RDS license key must be installed and configured on the server console to serve as the "root". When a new RDS session is started, it will execute the Startup procedure inherited from the server console, which includes a task to start a Host service. PC-Duo Host will distinguish the session from the server console and start up a Host service specifically for the session.
See "Host for RDS in section 5. Host Types" for complete information.
