In certain View environments, it is a priority to prohibit access to View desktops through the RDP display protocol. You can prevent users and administrators from using RDP to access View desktops by configuring pool settings and a group policy setting.
About this task
By default, while a user is logged in to a View desktop session, you can use RDP to connect to the virtual machine from outside of View. The RDP connection terminates the View desktop session, and the View user's unsaved data and settings might be lost. The View user cannot log in to the desktop until the external RDP connection is closed. To avoid this situation, disable the AllowDirectRDP setting.
Remote Desktop Services, called Terminal Services on Windows XP systems, must be started on the virtual machine that you use to create pools and on the virtual machines that are deployed in the pools. Remote Desktop Services are required for View Agent installation, SSO, and other View session-management operations.
Verify that the View Agent Configuration Administrative Template (ADM) file is installed in Active Directory. See Using View Group Policy Administrative Template Files.
