I have a new SBS 2003 R2 SP2 installation. The users report that they cannot edit any of their documents that are stored in the My Documents folder and redirected to the appropriate users' share on the server.
I have taken a look at the security and ownership of the folders from the server, and it looks correct. I've also done the "effective permissions" tab, and it shows full permissions. I've also checked and unchecked the "read-only" tab for the entire "Users" share.
I can't find what's keeping them from editing their documents.
