[Samba] Unable to join W2K domain

[Lehrnbecher-Hundt, Birgit]

Hello list,

I'm trying to join the W2K domain, but without success. 
After typing the following line
/usr/local/samba/bin/smbpasswd -j WORLD -r SRV5N -U adm
Password:
this message apears:
Unable to join domain WORLD

The content of smb.conf:


[global]
netbios name = SRVSX
security = domain
domain logons = yes
workgroup= WORLD
password server = SRV5N
keep alive = 30
os level = 0
domain master = no
local master = no
preferred master = no
username level = 8
password level = 8
encrypt passwords = yes
interfaces = 138.244.15.21/255.255.0.0
wins server = 172.17.0.41

(os: solaris2.6, samba: 2.2.2)

What's wrong?

Thanks in advance

Birgit
