DOCUMENT:Q142671  24-OCT-1996  [winnt]
TITLE   :Backup fails on certain directories due to lack of permissions
PRODUCT :Microsoft Windows NT
PROD/VER:4.00
OPER/SYS:WINDOWS
KEYWORDS:kbnetwork

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

- Microsoft Windows NT Workstation version 4.0
- Microsoft Windows NT Server version 4.0
------------------------------------------------------------------

SYMPTOMS
========

After you log on with an account that has Backup Operator permissions, when 
you run a backup across the network from a Windows NT 4.0 computer you may 
receive the following error in the backup.log file stating you do not have 
permissions to back up some directories:

   You do not have permission to access portions of data.
   Please see the owner or administrator to get permission.
   Directory F:\data

CAUSE
=====

An account with Backup Operator permission should have the built-in ability to 
back up files that it does not have permissions to access. However, this ability 
does not work properly in Windows NT 4.0.

RESOLUTION
==========

Microsoft has updated RDR.SYS to open remote files in the correct context.

This update is available from Microsoft support channels or directly from the
following Internet location:

 ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa
 /nt40/hotfixes-postSP1/NTBackup-fix 

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 4.0.
A supported fix is now available, but is not fully regression-tested and
should be applied only to systems experiencing this specific problem.
Unless you are severely impacted by this specific problem, Microsoft
recommends that you wait for the service pack release containing this fix.
Contact Microsoft Product Support Services for more information on the
availability of this fix.

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

The built-in ability of the backup operator works properly locally.
