Hi!
I have problems with it too. I have Service Pack 3. When I try logging in
with samba, I get this message:

Either you upgrade samba to support encrypted passwords which is the
best solution (see the other replies). But if you can't do that you
can force the NT machine to accept plain text passwords by changning
in the registry. Use the attached reg-file or run regedit and add in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Rdr\Parameters
a dword-field named EnablePlainTextPassword with value 1.
To get back encrypted passwords only just change the value to 0.

With Unencrypted Password SP3 Fails to Connect to SMB Server
Last reviewed: September 10, 1997
Article ID: Q166730
The information in this article applies to:
* Microsoft Windows NT Workstation version 4.0
* Microsoft Windows NT Server version 4.0
SYMPTOMS
After upgrading your Windows NT 4.0 computer to Service Pack 3
(SP3), you are unable to connect to SMB servers (such as Samba or
Hewlett-Packard (HP) LM/X or LAN Manager for UNIX) with an
unencrypted (plain text) password.
When attempting to connect after you upgrade to Windows NT 4.0
Service Pack 3, you receive the following error message:
System error 1240 has occurred.
The account is not authorized to login from this station.
Connecting to SMB servers (such as Samba or Hewlett-Packard (HP)
LM/X or LAN Manager for UNIX) with an unencrypted (plain text)
password fails after you upgrade to Windows NT 4.0 Service Pack 3.
CAUSE
This is because the SMB redirector in Service Pack 3 handles
unencrypted passwords differently than previous versions of Windows
NT. Beginning with Service Pack 3, the SMB redirector does not send
an unencrypted password unless you add a registry entry to enable
unencrypted passwords.
RESOLUTION
To enable unencrypted (plain text) passwords, modify the registry
in the following way:
WARNING: Using the registry editor incorrectly can cause serious,
system- wide problems that may require you to reinstall Windows NT.
Microsoft cannot guarantee that any problems resulting from the use
of the registry editor can be solved. Use this tool at your own
risk.
1. Run Registry Editor (Regedt32.exe).
2. From the HKEY_LOCAL_MACHINE subtree, go to the following key:
\system\currentcontrolset\services\rdr\parameters
3. Click Add Value on the Edit menu.
4. Add the following:
Value Name: EnablePlainTextPassword
Data Type: REG_DWORD
Data: 1
5. Click OK and then quit Registry Editor.
6. Shut down and restart Windows NT.
To enable unencrypted (plain text) passwords in an automated setup,
modify the registry in the following way:
WARNING: Using the registry editor incorrectly can cause serious,
system- wide problems that may require you to reinstall Windows NT.
Microsoft cannot guarantee that any problems resulting from the use

Add the following line to the Product.Add.Reg section of the
Update.inf file:
HKLM,System\CurrentControlSet\Services\Rdr\Parameters,
EnablePlainTextPassword, 0x10001, 1
