Network access control security problem
I am not a security expert nor an IT specialist but having a network of 7 terminals, some users are limited account others are administrators, some having XP OS others 98 and 2000.All the 6 terminals has to log on using a user name and a password when trying to click on any of the pc names in the workgroup network icons, except one terminal wich has win 98 OS is accessing directly the hard drive of a certain computer without even the necessity to log on with a user name and a password, i tried to eliminate any user name from the hard drive security tab in that accessed computer but the problem still, all other 6 computers need to log on with user and password . Can any one provide a step by step guide please to solve this matter and oblige the user of that computer to log on with a user name and a password each time he clicks the icon ?
i appreciate very much your help .Thank you .
