I have copied the following text from another question on here as it sums perfectly my issue but does not have a relevant answer for me...
"I did something I thought was right, but it messed things up this morning. When SBS 2008 makes redirected folders it gives users exclusive rights to their folders. It meant that Admins couldn't get to their folders, which does not work in our situation. When I tried to change permissions I could not, and when I went to the owner it said it could not be displayed. I read several answers that said to just change the owner for the folders to Domain Admins and then change the permissions. So I changed the ownerfor the root Redirected Folders share to the Administrators Group and then had that propagate to everything underneath. I then gave domain admins full control permissions over the root folder and had that propagate as well.
Well, then users could not get into their Documents folder! I temporarily fixed this by giving Users permission to the root folder and all subfolders."
Now I have faced big problems with new machines and hence need to reset the permissions and ownership of the folders - 80gb across 48 users.
Please could someone point me in the right direction with this one?
