[Samba] clients loose connection/cant save to samba server (samba-3.0.0-2)

[Denis Heitbrock]

hi,

i setup a samba-3.0.0-2 server under redhat 9. i added this server to a
win nt 4.0 domain controller. the nt domaincontroller only runs the
following services: wins, dhcp & pdc.
nothing more.

/etc/samba/smb.conf:
[global]
   workgroup = SCHLICK-ROTO
   server string = Server - File
   hosts allow = 172.24. 127.
   printcap name = /etc/printcap
   load printers = yes
   log file = /var/log/samba/log.%m
   max log size = 50
   security = domain
   password server = SV90005 SV90007
   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
   wins server = 172.24.90.5
   dns proxy = no

[Dokuser]
        vfs objects = extd_audit recycle
        comment = Dokuser
        valid users = @dokuadmin, at dokuuser, at domaenenadmin
        writeable = yes
        create mask = 0777
        directory mask = 0777
        path = /data1/Dokuser

w2k (sp3) & win nt 40 (sp5) clients got this problem. they open the file
and edit or made changes to the document. when they want to save the
file they cant. they get an error message and the work is lost. does
anyone got the same problems and/or maybe know a solution?
