I have a client who has all of thier important documents in a shared folder called company. This has been fully shared to everyone up to this point. It is now required that we limit the access to this folder to only the management of the company. Something I've done many times without problems. I setup a security group called Management and added the people who needed access to the folder. I then removed all permissions from the everyone, authenticated users, and users group and added only administrators and the new management security groups. I can't access this folder nor can anyone in the management or administrators groups. The ONLY way anyone can gain access to it is by adding the everyone group back to it.
So, in my frusteration, I created a brand new folder and setup the permissions I am looking for. Again...no one can access it. There is a user account called office admin that I have explicitly added and gave full control and still no dice. HELP! I can't find any DENY permissions anywhere and I have done a permissions audit which shows that she has full control. I am including some screenshots of the permissions. I have this setup on another client and I have tried everything the same as them and it's not working.
