problems joining NT domain

[Duane Davis]

I am attempting to setup samba using an NT server for authentication
but am unable to get samba to join the domain. I've added the samba
server into the NT's Server Manager as instructed in the docs and this
is what I get:

# ./smbpasswd -j domain      
doing parameter local master = No
pm_process() returned Yes
Added interface ip=10.0.0.23 bcast=10.0.0.255 nmask=255.255.255.0
resolve_name: Attempting lmhosts lookup for name AERIS-NT-SERVER<0x20>
Connecting to 10.0.0.135 at port 139
modify_trust_password: machine AERIS-NT-SERVER rejected the session
setup. Error was : code 131.
1999/06/15 14:20:27 : change_trust_account_password: Failed to change
password for domain DOMAIN.
Unable to join domain DOMAIN.

Here's my smb.conf:

# more smb.conf
# Samba config file created using SWAT
# from sft012 (10.0.0.32)
# Date: 1999/06/15 14:11:01

# Global parameters
[global]
        workgroup = DOMAIN
        netbios name = FILE-SERVER
        security = DOMAIN
        min passwd length = 3
        password server = aeris-nt-server
        log level = 3
        local master = No

[homes]
        comment = home directory space
        path = %H
        valid users = $S
        read only = No
        create mask = 0600
        directory mask = 0700
        locking = No

Any help would be appreciated.
