Q304334: PRB: Users w/ Proper Permissions Cannot GET Files on FTP Server

Article: Q304334
Product(s): Internet Information Server
Version(s): 5.0
Operating System(s): 
Keyword(s): kbWin2000PreSP3Fix

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Internet Information Services version 5.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When a File Transfer Protocol (FTP) client with proper permissions attempts to
GET a file on an Internet Information Services (IIS) FTP server, you may receive
the following error message:

  550 filename.xxx: Access is denied

CAUSE
=====

The file was previously deleted, but it remains on the FTP server because a
handle to the file was open at the time of the deletion attempt. The file is
actually pending deletion. This can result in a situation in which the Inetinfo
process has an open file handle that prevents access of a file by any other
local or remote user, and in which users are not disconnected on timeout. For an
example of how this can occur, see the "More Information" section.

RESOLUTION
==========

Use Move.exe or the MoveFileEx API to move the file to another location before
you delete it, so that the file does not appear in the folder contents on the
FTP server.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Internet Information
Services 5.0.

MORE INFORMATION
================

The FTP connection timeout does not close handles that are opened by a user.
When a connection timeout occurs, the FTP server checks for a transfer in
progress, which implies that a file handle is open. The FTP server resets the
connection timeout when a transfer is in progress, so the handle remains open
and the user remains connected.

Steps to Reproduce Behavior
---------------------------

1. In Internet Explorer, open a .zip file by using FTP and leave the download
  dialog box open.

2. FTP by using Ftp.exe and GET the file. Note that the file downloads as
  expected.

3. At a command prompt, type "del c:\inetpub\ftproot\file.zip" (without the
  quotation marks). The file appears to have been deleted.

4. FTP by using Ftp.exe and download the file. You receive a "550: access
  denied" error message.

5. At a command prompt, attempt to delete the file. You again receive the
  "access denied" error message.
