SYMPTOMS
=20
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
=20
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
=20
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:
=20
\system\currentcontrolset\services\rdr\parameters
3. Click Add Value on the Edit menu.
4. Add the following:
=20
Value Name: EnablePlainTextPassword
Data Type: REG_DWORD
Data: 1
=20
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
