[Samba] Can't add machine account to domain

[cmc at cat.savycat.com]

I am running samba-2.2.7a-7.9.0 on RedHat 9.0.  The domain I am trying 
to join has a different name than the workgroup I am trying to leave. 

Below is a copy of the last two entries of the computer_name.log, which 
are created when I try to add the machine account.

rpc_server/srv_samr_nt.c:_api_samr_create_user(1929)
  User carroll-313cny4$ does not exist in system password file (usually 
/etc/passwd). Cannot add account without a valid local system user.
                                                                                                                             
[2003/06/27 15:57:26, 0] rpc_server/srv_netlog_nt.c:get_md4pw(176)
  get_md4pw: Workstation carroll-313cny4$: no account in domain
