Hi John, I think you have 2 options: 1) you update your NT regestry with the NT4_PlainPassword.reg found in the docs dir in the samba source. or 2) You validate your passwords against a NT PDC.

It has worked beautifully for over a year now !UNTIL! recently we received the new MS Office suite which requires NT service pack 3. Since installing NT SP3 i get a message "the account is not authorized to login from this station" when I try to map a (previously used wnad working) samba-shared drive on my PC. I have since unistalled NT SP3 and tried again, and then it worked fine, so something loaded with SP3 is the problem. Any idea what? Anyone solved this problem? A solution would be oh so appreciated.
