The following error is observed when particular server has both Remote PC Agent and RD Session Host Agent installed:
Agents conflict. Server should have only one of the agents (PC or RDSH) installed depending on it's purpose.
If the server should be used as RDSH, Remote PC Agent should be removed and server should be rebooted if RAS installer prompted to do so.
If server should be used as Remote PC, RDSH Agent should be removed.
