[Samba] can't change user passwords from xp client machines

[Jeanne Schock]

All,

I am running samba v. 1.2 on a FreeBSD machine with XP clients. I cannot
make user password changes from  the XP machines using ctrl-alt-del > Change
Password. I followed some suggestions in the archives and on the net and
tried "guest account = smbnull." The result of this change was the exact
same error in the smbd log, only instead of 65534 (nobody), the log read 101
(smbnull).

I would appreciate any suggestions on how to approach this problem. Below
are log and smb.conf.
