DOCUMENT:Q130695 08-AUG-2001 [winnt] TITLE :ACLCONV Fails when Trying to Read ACL File PRODUCT :Microsoft Windows NT PROD/VER:3.50 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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.
