Article ID: 105214

Article Last Modified on 11/1/2006

APPLIES TO

Microsoft Windows NT Advanced Server 3.1
Microsoft Windows NT Workstation 3.1
Microsoft Windows NT Advanced Server 3.1

This article was previously published under Q105214

SYMPTOMS

Microsoft Windows NT 3.1 systems cannot see any files in a directory on a Hewlett-Packard (HP) LM/X 1.4 server if any file in the directory contains a period (or "dot") followed by more than seven characters. If you use the "dir" command to check the contents of the directory, you will receive the following message:

File Not Found.

CAUSE

HP LM/X 1.4 systems negotiate to Server Message Block (SMB) Specification Ext 2.0 (LAN Manager 1.x), which doesn't support long filenames. When speaking this down-level protocol, Windows NT 3.1 does not set bit 4 of Byte 9 of its SMBs. This bit is defined as follows:

   flags (smb_flg) bit 4:

   "When on, all paths sent to the server by the consumer are already in
   the canonicalized format used by OS/2. This means that file/directory
   names are in upper case, are valid characters and backslashes are used
   as separators."

STATUS

A fixed, untested version of the RDR.SYS driver is available from Microsoft Product Support Services.
