Windows NT Backup May Restore Truncated Macintosh Folder Names

ID: q106202

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1

SYMPTOMS

When you use the Windows NT Backup program to back up LAN Manager 2.x Services for Macintosh files, restored folders may not have their proper names restored. If the folder has a long filename, the restored folder name may be truncated to an 8.3-character filename. However, files will be restored with their proper names.

CAUSE

LAN Manager 2.x Services for Macintosh uses Extended Attributes (EAs) on both FAT and HPFS to store Macintosh information, including the LONGNAME. The Windows NT Backup program is not recognizing Extended Attributes on directories, but is recognizing them on long filenames, because they are restored.

STATUS

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