You do not have access to the folder '\\Dfs domain name'. See your administrator for access to this folder.
Or, you receive the following error message:
'\\domainname' could not be found. Check the spelling of the file name, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the File menu, make sure that the file has not been renamed, moved, or deleted.
