After installing a Citrix VDA, non-administrator users lose direct RDP access to the server.

For security reason, a new local group called Direct Access Users is created on each Virtual Delivery Agent.

To restore RDP access for non-administrators, you must add those users to this new "Direct Access Users" group on the VDA machine itself. 

• Open Computer Management:
  • On the VDA machine, right-click the Start button and select "Computer Management".
• Navigate to Local Users and Groups:
  • In the left-hand pane, expand "System Tools" and then "Local Users and Groups" to see the available groups.
• Open the Direct Access Users Group:
  • Double-click the "Direct Access Users" group to open its properties.
• Add Users:
  • Click the "Add" button, then enter the usernames of the non-administrators you want to grant RDP access to.
• Apply Changes:
  • Click "Check Names" to verify the users, then click "OK" and "Apply" to save the changes.
