[Cedar John]

I installed samba 2.0.8 in FreeBSD 4.3,when I use
# smbpasswd -j DB -r dbep_host1 -R wins
it display:
'Unknown parameter encountered: "domain controller"
Ignoring unknown parameter "domain controller"
modify_trust_password: Can't resolve address for DBEP_HOST1
2001/09/24 17:02:31 : change_trust_account_password: Failed to change =

or domain DB.

What can I do?
