Q130695: ACLCONV Fails when Trying to Read ACL File

Article: Q130695
Product(s): Microsoft Windows NT
Version(s): 3.50
Operating System(s): 
Keyword(s): 
Last Modified: 08-AUG-2001

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

- Microsoft Windows NT Server version 3.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

ACLCONV reads a LAN Manager ACL file and re-applies the permissions on the same
directory tree under Windows NT. When you run ACLCONV the following error
message may appear:

  error encountered reading data file.


CAUSE
=====

ACLCONV is unable to read ACL files that are modified using the append option.

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

In LAM Manager, the ACL file is created using BACKACC. There are two command
line options to BACCACC:

  /S  Recursively backup permissions for all the subdirectories & files.

  /A  Appends access permissions to existing backup file.

It is possible to collect permissions for just few directories. For example:

  BACKACC C:\DATA1 /F:C:\FILE.ACL /S

The FILE.ACL file is created, and permissions for DATA1 are stored.

If you the run BACKACC C:\DATA2 /F:C:\FILE.ACL /S /A, permissions for C:\DATA2
are appended to FILE.ACL file

When the system is upgraded to Windows NT, or if the directory trees are copied
to another computer running Windows NT, ACLCONV is used to reapply the
permissions. This only apples to an Windows NT file system (NTFS) formatted
partition.

Following the above example, running ACLCONV /DATA:FILE.ACL /LOG:FILE.LOG will
cause the following error message to appear:

  Error Encountered reading data file.

RESOLUTION
==========

To work around this problem, run BACKACC to create separate ACL files and then
run ACLCONV to restore permissions, or run BACKACC to collect ACLs for the
entire drive and then restore them. For example, on a LAN Manager system, run:

  BACKACC C:\DATA1 /F:C:\FILE1.ACL /S
  BACKACC C:\DATA2 /F:C:\FILE2.ACL /S

On an Windows NT system, run:

  ACLCONV /DATA:FILE1.ACL /LOG:FILE1.LOG
  ACLCONV /DATA:FILE2.ACL /LOG:FILE2.LOG

STATUS
======

Microsoft has confirmed this to be a problem in Windows NT version 3.5. We are
researching this problem and will post new information here in the Microsoft
Knowledge Base as it becomes available.
