A user profile describes the configuration for a specific user, including the user's environment and preference settings. Unless you plan and manage user profiles in an RD Session Host server environment, user profiles can become large in size and can cause problems, such as slow logon times, when a user connects to an RD Session Host server. User profile management is also important when users connect to several different RD Session Host servers or connect to RD Session Host servers in remote locations.
