NT 4.0 Service Pack 3 breaks SAMBA (the UNIX public domain CIFS file server).

The Service Pack 3 Documentation Section 3.6 reads:

: 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.

However, Article Q166730 does NOT exist on http://www.microsoft.com/kb/

I Spoke with Technical Support, and they said that this KB article and
several others mentioned in the README file did not exist!

So I was transfered to NT 4.0 Workstation Support. They were completely
unaware that SP3 broke mounting from a Unix server which uses Unix style
passwords.

The product engineer said he will send me Q166730 but he told me I am not
allowed to share it to anyone else when I eventually get it.

I called back a few hours later, and the engineer told me that even he
did not have it so he would have to esculate the call to the developer.

Findally a developer gave me the registry entry to make samba work again.
The developer told me he wasnt exactly sure why no one had the correct
permissions to access the page. But here is the registry entry necessary:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Rdr\Parameters]
"EnablePlainTextPassword"=dword:00000001
