Keine Serverprofile mehr, XP-Client plötzlich Master

Hallo,

ich habe in einem heterogenen Netzwerk mit einem Sambaserver (Samba 3.2.5) auf Debian/Linux (Lenny), das Problem, daß sich die WindowsXPProf-Clients von einem Tag auf den anderen nicht am dem Samba-Server, der als PDC konfiguriert ist, anmelden können. Das zeigt sich an den Clients so, daß sie die Serverprofile und das home-Share nicht verbinden können.

Die smb.conf sieht wie folgt aus:

[global]
netbios name = SAMBA
workgroup = GASPERSLOUIS-AG
server string = %h SAMBA (Samba-Server %v)
wins support = yes
dns proxy = no
name resolve order = lmhosts host wins bcast
interfaces = eth0
log file = /var/log/samba/log.%m
max log size = 1000
syslog = 0
panic action = /usr/share/samba/panic-action %d
security = user
encrypt passwords = true
passdb backend = tdbsam:/var/lib/samba/passdb.tdb guest
obey pam restrictions = yes
invalid users = root
unix password sync = no
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessf
ully* .
local master = yes
preferred master = yes
os level = 100
domain master = yes
domain logons = yes
admin users = @samba-admins,root
logon path = \\192.168.123.3\profiles\%U
;logon path = \\192.168.123.20\homes\%U
logon drive = h:

logon script = logon.cmd
add user script = /usr/sbin/useradd -m %u

create mode = 777

force create mode = 660
force directory mode = 660

[IMV]

comment = IMV-Daten
create mode = 777

force create mode = 660
force directory mode = 660

path = /home/IMV
[K-TEL]

force create mode = 660
force directory mode = 660

[Datensicherung]

force create mode = 660
force directory mode = 660

[makler2000]
readonly = no
comment = Makler2000-Dateien
create mode = 777
directory mode = 777
force create mode = 660
force directory mode = 660
public = yes
path = /home/makler2000

Um kurz zu machen, ich vermute, daß der XPprof-Client "MAKLER07" sich ungerechtfertig zum Master bzw. zum Server gemacht hat. Denn ein
"smbclient -L samba" liefert
Domain=[GASPERSLOUIS-AG] OS=[Unix] Server=[Samba 3.2.5]

Server Comment
--------- -------
MAKLER07
SAMBA samba SAMBA (Samba-Server 3.2.5)

Workgroup Master
--------- -------
GASPERSLOUIS-AG MAKLER07

Was muß ich eventuell am Client oder auch am Server einstellen, daß der Client seinen Master-Status verliert?

Vielen Dank,
