SYMPTOMS
If you use CopyDoubler to copy a folder from a SuperDoubler Macintosh computer to a Services for Macintosh (SFM) volume on a Windows NT Server, then try to re-copy the folder to the same volume by choosing Fast Replace when prompted, you get this error:

Error -48 (dupFNErr) Duplicate filename (rename)



CAUSE
For a Fast Replace of an existing folder (which means that no changes have been made to the folder) CopyDoubler requires directory enumerations to return entries in alphabetical order. If they are not returned this way, CopyDoubler tries to create the first directory (alphabetically) on the server. This causes an Object Exists error on the server, so CopyDoubler issues error -48 (DuplicateFileName).



WORKAROUND
Instead of the Fast Replace option, use Normal Replace with CopyDoubler.



STATUS
This is a design incompatibility. Services for Macintosh and the AFP spec do not require that filenames be returned in alphabetical order from a directory enumerate.
