NT to LAN Manager UAS Replication Problem after using PORTUAS

 Last reviewed: September 14, 1995

The information in this article applies to: 

  - Microsoft Windows NT Server version 3.5

SYMPTOMS

When the user account database (UAS) is ported from a LAN Manager server to a Windows NT 3.5 server (using PORTUAS) and later modified, UAS replication problems may occur. The LAN Manager server's error log may contain Error 3226, with the following two bytes in the data field: 

   00 EA
These two bytes represent "ERROR_MORE_DATA." This error is the final return code; the actual error is: 

   0x57 (ERROR_INVALID_PARAMETER)
This error is not recorded in the LAN Manager server error log. The replication process is halted and UAS replication is never successfully completes.

CAUSE

If a home directory exists for a user account that is being ported, then PORTUAS sets a flag UF_HOMEDIR_REQUIRED FLAG (bit 3 in usri2_flags) indicating home directory is required. If the user account is later modified to not include a home directory, Windows NT does not reset this bit.

When a home directory is specified for a user account that was created using User Manager (or Net User ), UF_HOMEDIR_REQUIRED FLAG is not set. Therefore, UAS replication works correctly.

RESOLUTION

To correct this problem, clear the UF_HOMEDIR_REQUIRED FLAG when Windows NT replicates to a LAN Manager Backup Domain controller.

STATUS
