I thought it would be best to put my issue here as i get the same issue on Windows 7 & 8.1
This issue first came about when one of our new staff told me they kept getting 'you need permission to perform this action' when creating a new folder or editing existing files on a shared network drive.
Now i am a domain administrator and being a shared network drive i have double and tripled checked that she has access as her permissions on this drive are set to 'full control'. The current owner on this drive is the 'DOMAIN\Administrators' group. I am an administrator myself and my account is a member of 'DOMAIN\Administrators' and even i get the same 'you need permission to perform this action' message. Even when i try to create a new shared folder on the server and map the drive, i get the same error.
This user has 6 network drives mapped to her account. Out of those, 4 other drives allow here to add, edit and delete files without any issues, except the other 2 which seem to be causing problem to her and myself. I have checked the settings of these working shared network drives and cant see anything different. The pictures below however are what i have mapped to my own administrator account and it still asks for Administrators permission even though i am an administrator!?
I haven't attempted a restart of the server yet. Current Server architecture is Windows 2012 R2
