I know i can disable the taskmanager time but that's not my goal, all i want to achieve is the removal of the user tab from the taskmanager on a w2k3 ts so users cannot see eachother but are still able to kill their own process if needed.

Windows Server 2003 still logged every game failed attempt to log on (which is good).
