6011.0. "NT 4.0 SP3 and PATHWORKS V4" by RDVAX::akocstdhcp104-25.ako.dec.com::levy (Run Like an Antelope) Fri May 16 1997 06:31

I just installed NT 4.0 SP3 on my workstation.

Since doing so, I am unable to connect to my VMS directory on a 
PATHWORKS V4 system.  There are no intrusions on the VMS system.

On the VMS side, I see the normal activity as far as the two failed 
login attempts:

 %%%%%%%%%%%  OPCOM  16-MAY-1997 08:14:46.45  %%%%%%%%%%%
 Message from user SYSTEM on CRA
 Login breakin attempt detected on PC file server from client node 
 bg5861


 %%%%%%%%%%%  OPCOM  16-MAY-1997 08:14:46.61  %%%%%%%%%%%
 Message from user SYSTEM on CRA
 Login breakin attempt detected on PC file server from client node 
 bg5865 on account LEVY

The message I get is "The account is not authorized to login from 
this station."

I am able to connect ok from an NT 4.0 SP2 system.

Now, perhaps this problem could be considered a feature, since it may 
encourage us to finally rid ourselves of this dinosaur, but I'm 
wondering if anyone has any insights as to why SP3 would change this 
behavior.

Thanks!

    From the readme file:
    
    
    3.6 Unencrypted Passwords No Longer Sent by Default
    ---------------------------------------------------
    Connecting to SMB servers (such as Samba and LAN Manager for UNIX)
    with an unencrypted (plain text) password fails after upgrading to 
    Windows NT 4.0 Service Pack 3. 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 will not send an unencrypted password unless you add 
    a registry entry to enable unencrypted passwords. For information 
    on how to modify the registry, search the Microsoft Knowledge Base 
    at http://www.microsoft.com/kb/ for the following article: Q166730.
    This article also contains information on how to change the 
    Service Pack setup process so that unencrypted passwords are
    enabled after the Service Pack is installed.

That's what I get for not doing my homework.

Thanks!

6011.3Article doesn't seem to existRDVAX::akocstdhcp104-25.ako.dec.com::levyRun Like an AntelopeFri May 16 1997 09:4610
Well, the article quoted in the readme file is not found in the KB, 
either querying by keyword or by looking up "unencrypted password".

Has anybody managed to retrieve this bit of information from 
Microsoft?

Thanks!

    SYMPTOMS
    
    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
