Foi o que fiz para bloquear a área de trabalho para ficar acessível apenas para administradores de servidor e um grupo de AD nomeado. Os usuários que não são membros do grupo AD especificado receberão uma mensagem informando que devem usar o RDWeb e não o mstsc da área de trabalho / padrão.
- Crie um vbscript e coloque-o em uma pasta no servidor que todos os usuários possam ler + executar
Adicione a seguinte linha ao %windir%\system32\USRLOGON.CMD
cscript <sourcefolder>\DesktopUserCheck.vbs
