I setup a share folder called company, everyone able to access it on the network. I created another folder inside company folder called Accounting, and only people in accounting gp can access it. I first created account gp and put the users in the gp.
On the security tab of accounting folder, I removed the domain users and dded the accounting gp and gave full permission. So now, only system, domain admin, accounting gp and administrators in the security tab. But when I tested, it says you do not have permission.... However, if I added the single user there, it would work.
