NT Workstation can not access shares

[Jesus Colprim]

I had also this problem and I solved it accessing at the windows NT
register. The problem is that samba used non encripted password and
Windows NT uses them as a the user "guest". If you look at the samba log
file you will find:
access guest no available

To solve this, on the windows NT: (ref. microsoft kb)
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.

TITLE   :With Unencrypted Password SP3 Fails to Connect to SMB Server

PRODUCT :Microsoft Windows NT

PROD/VER:4.0

OPER/SYS:winnt

KEYWORDS:NTSrvWkst kbnetwork kbbuglist kbfixlist



======================================================================

--------------------------------------------------------------------------

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 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
