My friend Jerry has a Dell Inspiron 8600 with Pentium M 1.20 GHz running Windows XP Professional. For whatever reason, one I can't for the life of me figure out, EVERY time he tries to open ANY application he gets this error message: "This operation has been cancelled due to restrictions in effect on this computer. Please contact the system administrator." I checked the Microsoft website (from my computer) but all they recommened is modifying the GPO by looking under 'User Configuration'. I have no freaking idea what the hell they're talking about. Is there anyone here who can help?
