TITLE   :Windows NT: LAN Manager FTP Clients Require a Password
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:

----------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft Windows NT operating system, version 3.1
 - Microsoft Windows NT Advanced Server, version 3.1
----------------------------------------------------------------------
 
SYMPTOMS
========
 
Microsoft LAN Manager file transfer protocol (FTP) clients may not be
allowed to establish a session with a Windows NT FTP server even
though they have a valid user account on the Windows NT machine.
 
CAUSE
=====
 
LAN Manager FTP clients that use the TCP/IP Utilities for LAN Manager
require a password to attempt to establish a session with an FTP
server.
 
Even if a blank password is valid for the Windows NT user account,
such as the Guest account, the LAN Manager FTP Client will not be able
to establish a session.
 
RESOLUTION
==========
 
To work around this problem, use the User Manager to add a password
(which is not blank) to any user account that will be establishing a
session with the FTP Server.
 
To modify or add a Password to an existing account, in the User
Manager, highlight the appropriate account, select User, choose
Properties, and enter a password in the two Password fields.
 
It is also possible to configure Windows NT to require a password for
all user accounts. To configure Windows NT to require passwords, in
User Manager, select Policies, choose Account Policy, and change the
Minimum Password Length option to 1 character or more.
 
Windows NT FTP clients do not require a password with their account to
establish a session with a Windows NT FTP server.
