Restrict access to system command propmt

Question

Hi, 
 
 We have restricted use of the run command within Windows and hidden the C drive from users within explorer however users can fork out to a command window within Microstation by using the ! or % key-ins. This gives them access to the hidden C drive etc. Is there a way to restrict the use of the ! and % key-ins to stop users from bringing up this system command window? 
 
 Regards 
 Colin

Two things come to mind... develop and use an application that filters the input queue for those key-ins and rejects them or take a look at disabling the command prompt through Group Policy (there are quite a number of hits on the internet for the latter, along with disclaimers about things to take into account).
