Windows Server : Managing the Terminal Services - RDP Permissions

Managing the terminal services includes various tasks such as assigning RDP permissions, configuring connection limits, session time limits, assigning session permissions, viewing process, monitoring sessions, logging off users, disconnect sessions, and resetting the terminal services. Terminal Services Manager is used to perform these administrative tasks. Ensure you have a thorough understanding of every task and the implications before you apply it on a production network. Improper configuration of permissions may result in assigning additional permissions to the users where not required and inadequate access where required.

RDP Permissions

Terminal Services Manager allows you to configure various RDP permissions. Permission sets such as Full Control, User Access, Guest Access, and Special Permissions can be assigned to users, clients, and groups. Each permission set has one or more permissions (see Tables 1 and 23). Figure 1 shows the RDP properties. Figure 2 shows the advanced security settings for RDP. Figure 3 shows RDP permissions.
