Trouble joining a NT domain with Samba 2.07

[Mark D. Wehner]

[root at sysadmin samba]# smbpasswd -j ENT21
cli_net_req_chal: Error NT_STATUS_INVALID_COMPUTER_NAME
cli_nt_setup_creds: request challenge failed
modify_trust_password: unable to setup the PDC credentials to machine
ENTERPRISE21. Error was : NT_STATUS_INVALID_COMPUTER_NAME.
2000/06/22 14:12:30 : change_trust_account_password: Failed to change
password for domain ENT21.
Unable to join domain ENT21.


this is the error I get.  I'm thinking that I'm making a newbie
mistake... Anyone have advice?
