Mysterious user authentication failure on basic network

Hi Bill,

Good on you mate! Thanks for your reply. Whilst trying encrypted passwords
in smb.conf was something I had tried already without success, your pointer
to encryption as the cause was of course spot on. I made the clear text
registry entry changes to both Win95B and Win98SE PCs and all worked
perfectly. In short, I agree with you and I think that SAMBA and Windows
don't always get their encryption alligned (no really rigorous hard
research, just a hunch of mine at this stage but I found that my SAMBA
server talked on a 2m piece of coax to a Win95B machine and simply worked
first time but when I moved the SAMBA server to a larger live network that
was when the encryption problem got me.)

 *** Clear text solved the problem ***

The only unresolved issue that is playing on my mind is why one Win95B PC
worked first time whereas another Win95B PC needed the registry changed to
clear text before it would work..... anyway, since it works I am happy for
now and can overlook this apparent mystery.

I hope this info helps someone else too and saves them the 2 late nights I
have had on this one ...

Many thanks again for your help Bill.
