What permission is required to create Remote Desktop Apps using the Powershell RDS provider?

I am trying to resolve the Access denied error. The user that is attempting to run the script remotely is a member of the Remote Desktop Users group on the remote machine. The user is NOT a member of the local administrators group on the remote machine. I would prefer not to make them an administrator if there is another option.

Does anyone know how this can be done?

Thanks,

Matthew

When I attempt to run a powershell script that create remote apps on another computer I get the following error:

[USTSDEV3] Connecting to remote server USTSDEV3 failed with the following 
   error message: Access is denied. For more information, see the about_Remote_Troubleshooting Help topic.
             + CategoryInfo          : OpenError: (USTSDEV3:String) [], PSRemotingTrans 
            portException

Batch file command that attempts to launch the powershell script on a remote computer:

Powershell -Command "Invoke-Command -ComputerName %TERMINAL_SERVER% -FilePath .\CreateRemoteApps.ps1"
