[Samba] Problem joining 3.0.2a to W2k AD

[Adam Aube]

When attempting to join my Samba box to my AD domain, I get the following:

# ./net rpc join -I 192.168.0.20 -U administrator
Password:
[2004/04/21 16:18:30, 0] rpc_client/cli_netlogon.c:cli_nt_setup_creds(249)
  cli_nt_setup_creds: request challenge failed
[2004/04/21 16:18:30, 0] utils/net_rpc_join.c:net_rpc_join_newstyle(326)
  Error domain join verification (reused connection):
NT_STATUS_INVALID_COMPUTER_NAME

Unable to join domain OTSHDQTR.
# 

The machine account is created in AD when I run net join. I have been
deleting it between attempts to join the domain,

I am running Samba 3.0.2a on Debian GNU/Linux 3.0r2. My domain is a Windows
2000 mixed-mode domain with no WINS server. Samba was compiled from source
with the following options:

--with-prefix=/opt/samba --with-winbind

My smb.conf file is as follows:

[global]
  workgroup = OTSHDQTR
  netbios name = DEBSERV1
  security = domain
  password server = 192.168.0.20
  client ntlmv2 auth = yes
  log file = /opt/samba/var/log/log.%m
  log level = 3
  winbind use default domain = yes

Searching Google and the archives turned up a single hit: a nearly identical
problem (posted April 14th) that nobody responded to.

Any suggestions?
