So a week ago we moved our fileserver shares to dfs shares. And updated a GPO that had not worked for a while. This had done so some users did not have a folder under the filseshare for users for redirect of Documents Folder.
This caused this error msg on changing or renaming a file.
To rectify this issue, create the users folder on the shared drive and give the user full access to the folder.
