Encrypted passwd not working in NT/SP3 and Win95

[Biswajit Sain]

Consequent to my question asking why samba does not work with NT/SP3
client when encryption is enabled, Gerry replied thus:

::Upgrade to the newest version of samba first.  By stating that you are

But since then, I have upgraded to the latest samba (1.9.18p2) and am using
the des package included with it. I have encrypt password = yes in smb.conf.
However, I do not want to set the "plain text" mode in registry, for, then
it defeats the whole purpose of encryption -> NT/SP3 will then not encrypt
the password while sending to samba server. 
What I want is, NT/SP3 as well as Win95 *should* send encrypted passwords
(thus, I should not have to set "plaintext" password in registry), which 
Samba server should successfully match locally. With current setting, having
compiled and installed samba with encryption enabled, I am able to access
shares from Win95 using encrypted password, but not from NT/SP3.
Can anybody suggest how to handle this?
