From the README.TXT that comes with NT Service Pack 3:
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.
Everything you need to know as to how to fix this evil little problem is described in their document called With Unencrypted Password SP3 Fails to Connect to SMB Server .
Thanks to Oscar Miranda for this hint.
I have been running a Netware 32 Client (for my Novell mounts here at work) and found that if the NT name of my PC is the same as my Netware logon id, then I had this problem. Now I am prompted only the once for my SAMBA password (even though it IS the same as my Netware password.
I also found that by changing the name of the PC to be different to my Netware login name, I also got rid of those banner pages on my Netware printouts that I was previously unable to remove.
