FTP Clients Cannot Rename Files on Remote FTP Virtual Directory

ID: Q172416


The information in this article applies to:
  • Microsoft Internet Information Server version 4.0


SYMPTOMS

When you connect to an FTP virtual directory that points to a remote Microsoft Windows NT Server (using either an NTFS or FAT partition), you can not rename a file that resides in that directory, even if you have full control to the share or NTFS permissions. When you try to rename the file, you will get the following error message:

Error 500: Access is denied.
All other actions can be completed as expected (put, get, delete). Also, a file located in a local virtual directory may be successfully renamed.


CAUSE

The FTP protocol has a two step rename process. The first, RNFR (Rename From), does not attempt to impersonate the UNC user when checking file attributes.


RESOLUTION

A supported fix that corrects this problem is now available from Microsoft, but it has not been fully regression tested and should be applied only to systems experiencing this specific problem. If you are not severely affected by this specific problem, Microsoft recommends that you wait for the next Windows NT service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information on support costs, please go to the following address on the World Wide Web:
