We are facing a issue regarding sharing and file permissions. We have made a folder (lets suppose X) on our File Server (Windows 2003 Server R2 Ent. Ed.) and enabled sharing permissions for all Users (Including A and B groups). Now we made separate folders under X for A and B groups called Y and Z. Now we have given full control to A and B groups to y and Z respectively. We want that they cant access each other folders. Now one of the members of A group made a folder under its Y folder and gave access and direct UNC path to one of the members of B group. That member of B group can access the folder under the prohibited one. How could it possible, is it bug?
