[Samba] Help! Add samba server to Win2000 Domain

[Jack]

Hi,
I am trying to add samba server(3.0.4) in Solaris to win2000 domain, then
all PC in the domain can see the share drive in Solaris.
Followed the manual:

root#  groupadd machines
root# /usr/sbin/useradd -g machines -d /dev/null -c "machine nickname" -s
/bin/false machine_name$
root# passwd -l machine_name$
root# smbpasswd -a -m machine_name

1. On the MS Windows NT Domain Controller, using the Server Manager, add a
machine account for the Samba server.
2. On the UNIX/Linux system execute:
root# net rpc join -U administrator%password

successfully.

But when I tried to from the Win2000 pc to access the samba server, it
failed. Did I miss something?
Please help!!
