I was trying to setup permission to users, leaving admin only access to one drive. Unfortunately after applying the perimissions, the drive is not accessible anymore. The security tab is also missing from the properties window. I'm afraid something may have messed up and all permissions to admins and everyone was removed. Is there anyway to bring back the security tab and restore permissions to administrators?

Hi This guide is for Windows Vista but it should work the same way in Windows 7 http://www.vistax64.com/tutorials/140723-security-properties-tab-restore-remove.html I Hope it will help you. Best Regards Chris Steding MCTS Windows 7 Configuration www.compit.se

Hi, If the machine is in a domain, you should modify the Group Policy in the server side. However, if the issue persists after performing Chris’s suggestions, I suggest you perform a System Restore for a test. Thanks, Novak
