Has anyone here successful joined a RHEL 3 machine as a member sever to
a Windows 2000 domain?

Here is my smb.conf file:
1. my windows 2000 domain is called TEST
2. my linux machine netbios name is called lxs01 which is the actual
machine name

[root@lxs01 samba]# more smb.conf
# Global parameters
[global]
        workgroup = TEST
        server string = Test Samba Server
        netbios name = lxs01
        security = domain
        log file = /var/log/samba/%m.log
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        dns proxy = No
        hosts allow = 192.168.1. 192.168.1.X
        wins server = 192.168.1.X
        idmap uid = 15000 - 20000
        idmap gid = 15000 - 20000
        winbind use default domain = Yes

[homes]
        comment = Home Directories
        #path = /home/testuser
        valid users = %S
        #guest ok = No
        read only = No
        browseable = Yes

Here is what happens

when I issue the following command:

net rpc join -Uadministrator%'admin-password'
[root@lxs01 log]# net rpc join -I 192.168.1.226
-Uadministrator%'admin123'
