>I'm ftping a file to a Unix system using the windows api ftpPutfile, I then try to rename that file using ftpRenameFile. When I try to rename the file I get error number 2 or, occasionally 183. Even though I get an error every time, the file is always renamed successfully. Has anyone got an ideas as to why I'm getting these errors?

If these are Windows error numbers, 2 is the file doesn't exist and 183 is that the file can't be created because it already exists. Other than that, I won't even guess why you're getting them.
