When the Internet Lock is engaged, programs given pass-lock permission can continue to access the Internet. If you grant pass-lock permission to a program, and that program uses other applications to perform its functions (for example, services.exe), be sure to give those other programs pass-lock permission as well. A key symbol in the Lock column indicates that the program has pass-lock privilege.
To grant or revoke pass-lock privilege:
Select Program Control|Programs.
Select a program from the list, then click in the Lock column.
Select Pass Lock or Normal from the shortcut menu.
