Upgrade to the newest version of samba first.  By stating that you are
using libdes-4.01 I would assume you have an old version.  The
encryption support is buitl in now.

Also I am assuming that you do have encrypt password = yes in smb.conf
as well.  If not and you have not enabled the plain text password
registry setting ( see docs/NT4_PlainPassword.reg ), then you would
experince the problems you are describing.

Hope this helps,
