Ответ: NTFS Permissions Help for File server
Thank you all,
I have tried :
Folder properties - Security - Advanced - Replace permiccion entries on all child objects...
Check and press OK.
But it did not help.
So i made one thing :
1)create 2 folder : department and departments_s
in department folder i create all units (it,marketing,sales.....)
now on department folder i give no permission to everyone,but on folders inside i give: fot IT folder , give group fro Active directory : Information technologies all permission.
similar to finance folder (all permissions to finance group from active directory)
2) in folder department_s i create only shortcuts to folder department/it (or sales or marketing)
so users can go to folder using a shortcut and its more safe.
shortcut must be like : //"server_name"/department/it
it helped me.
