LAN Manager FTP Clients Require a Password

• 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.
