The users in a View environment access the virtual desktop via the RDP protocol. For that to work the user needs to have special access rights. As a standard only the administrator has direct RDP access to the remote system. To configure access for the user you could do that on a per desktop basis manually what would be time consuming or you can use the Group Policy Objects within the Active Directory which is the recommended way. First of all you’ll need to figure out who should get remote access and create one or more user groups in the Active Directory. In this example the groups is called vditestusers and it’s a member of the domain TEST. Diese This group will be a member of the local group Remote Desktop Users on the virtual desktop which has the needed remote access rights. For that reason you’ll need to configure the group in the GPO’s as a Restricted Group.
After that add configure the group as a member of the local group Remote Desktop users and the users will have remote access.
In the last step you need to allow the users to connect remotly using the Terminal Services. There is an option within the administrative templates to do that. Just go to: Computer Configuration, Administrative Templates, Windows Components and then Terminal Services. This option will enable the Remote Access on the desktop operating system.
