## SYMPTOMS

When you run ACLCONV (used to convert LAN Manager access control lists [ACLs] to Windows NT permissions on Windows NT file system [NTFS] files), it incorrectly replaces permissions for mapped accounts and reports the following error in the ACLCONV log:
User or Group ID not found.

## CAUSE

ACLCONV does not read the ACLWORK.DAT file and is therefore unaware of the account mappings.

## STATUS

Microsoft has confirmed this to be a problem in Windows NT versions 3.1 and 3.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

## MORE INFORMATION

USERCONV.EXE allows you to map accounts from the LAN Manager domain to the Windows NT domain using NETACC.BKP for input. USERCONV displays a list of the accounts on the LAN Manager server and the Windows NT server. You can map one or more LAN Manager accounts to one Windows NT account. You can keep the same account names when upgrading from LAN Manager to Windows NT, or you can have all of the permissions currently granted to a LAN Manager group (for example, Operators) assigned to a new Windows NT domain group (for example, Server Operators).
USERCONV updates the user account database with the LAN Manager accounts that were not mapped, and creates a data file, that contains all of the account mapping information. ACLWORK.DAT contains these mappings and USERWORK.DAT contains a text version of the mappings.
ACLCONV is supposed to read ACLWORK.DAT. ACLCONV reads the ACLBAKx.ACL file that was created on the LAN Manager server and updates permissions on the Windows NT volume to correspond to the previous permissions on the HPFS volume. USERCONV should search the ACLWORK.DAT file for all of the user IDs it reads from the ACL backup file. If no account mapping is found, it should update the permissions for the user account of the same name. If a mapping is found in the ACLWORK.DAT file, the permissions should be transferred to the new account name.
