I have an enduser running Vista Bussiness. When they try to rename a folder or a file on a dfs share they get a message that stats: You need permission to perform this action. The user has modify rights to the folder and files contained within it. I have recently replaced their laptop. The original laptop is running XP and the user is able to make all they changes they want to the dfs share. I have disabled UAC, made the user the local admin, and disabled the firewall. I have also enabled auditing on the server but it does not report any failures.
