Only enable program for specifc users

[KeyserSoze]

I want to allow a program to be run only for specific users. I know about RestrictRun, but it only allows me to specify the programs I want to allow, not the one I don't want. As I only only want to block one program, I would have to specify EVERY single other program on the computer except for the one I want to block.

Is there an inverse to RestrictRun? That is, let me specify the programs I don't want to allow?

More info: The program is run through a context menu selection(right click option). Is there a way to add context menu options only for certain users? I don't want to disable the entire context menu, just the entry for the program I want to block.

Any help or ideas would be greatly appreciated!

Partial Answer:

you do not give us any information on OS used, so some guesswork involved:

if using WinNT/2K: modify Permissions on the EXE file so that only selected users or user groups may execute the code (remove EVERYONE).

If other OS but running in a server environment: put EXE on a share with access restricted to the selected users.

any other case: difficult to restrict for knowledgable users - can't you remove the context entry and replace by a shortcut in Start>Program?
