I have a server that is running windows storage server 2008r2 that I am moving allot of data to.<br />
I have two folders on the same drive, one called departments and the other is user.<br />
Department has subfolder &nbsp;for all departmental shared data and the users contain the users home folder. We turned off UAC which required a reboot, after the reboot user were able to access their home folders but no one could access any department shares. When I look at the security on all the share foldesr under department the security showed local Admin, Domain Admin and system, the entry for the groups was just a SID. I went thru all the shared folders and delete the SID entry and reassigned security for groups on all the shared folder. does anyone know why this happened, I still have allot of data to move and a lot more shared folders to create and this server will need to be rebooted when any updates are applied and I do not want to have this issue again. any help would be appreciated
