All users, except Admin, only would be able to run a specific application in Windows Server.
I am new in Windows Server. What I did is: for each user, I changed the environment configuration and in "Start the following program at logon", under "Local Users and Groups \ Users".
It works great, when the user logs on, the application is automatically executed. They do not see the desktop. When they close the application, the session is automatically log off also. However there are 2 problems:
1-From the application, using Open or Save File option, they can see all folders in unit C:. I have tried to deny permissions for the entire C: but a bunch of errors arises.
2-If they do Ctrl+Alt+Del, they can access to Task Manager and from there, they can execute any other program. I have tried to deny the access to TASKMGR.EX from security sheet, but the "Add" button for adding a group or user is disabled.
How can I solve these two problems?
