Hjælp til Samba som PDC server

Jeg har prøvet at sætte SAMBA op som PDC server på min linux server, men min win98 client har slet ikke reageret på den. Hvad gør jeg galt? Desuden vil den ikke så gerne acceptere "domain admin users = root".

Min smb.conf ser sådan ud:

[GLOBAL]
workgroup = AA
encrypt passwords = Yes
socket options = SO_KEEPALIVE IPTOS_LOWDELAY TCP_NODELAY
Character set = ISO8859-15
ös level = 65
preferred master = yes
security = user
status = yes
logon script = %U.bat
add user script = /usr/sbin/useradd -d /dev/null -g 100 -s /bin/false -M %u
guest account = ftp
share modes = no
logon path = \\server1\profiles\%u

logon drive = H:
logon home = \\server1\%u
domain admin users = root
kernel oplocks = No
printing = lprng
Netbios name = Server1

smb passwd file = /etc/samba/smbpasswd
unix password sync = yes
passwd program = /usr/bin/passwd %u

[homes]
  guest ok = no
  read only = no
  create mask = 0700
  directory mask = 0700
  oplocks = false
  locking = no
  Browsable = No

[netlogon]
  path = /home/domain/netlogon
  writable = no
  browseable = yes
  guest ok = yes

[profiles]
  path = /home/domain/profile
  writable = yes
  browseable = no
