The FreeBSD Diary

Casper try this:

           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 Server Message Block (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
      of the registry editor can be solved. Use this tool at your own risk.

      Add the following line to the Product.Add.Reg section of the 
      Update.inf file:

         HKLM,System\CurrentControlSet\Services\Rdr\Parameters,
         "EnablePlainTextPassword", 0x10001, 1
