[Samba] Problem with Samba PDC and WIN2000

[Santiago Avila]

Hi,

I just installed a Samba Server as a PDC and my WIN9X machines worked 
just fine, but I can´t join WIN2000 Clients to the domain.
I created the Trust Account but when a join the domain I get the message.
"The following error occured attempting to join the domain "TECNICO""
Logon failure: unknown user name or bad password

Also, in the /var/log/samba/taller.log I got

[2003/01/29 19:41:23,0] rpc_server/srv_samr.c:api_samr_set_userinfo(672)
  api_samr_set_userinfo: Unable to unmarshall SAMR_Q_SET_USERINFO.
[2003/01/29 19:41:23, 0] passdb/smbpass.c:startsmbfilepwent_internal(87)
  startsmbfilepwent_internal: unable to open file /etc/samba/smbpasswd. 
Error was Permission denied
[2003/01/29 19:41:23, 0] passdb/smbpass.c:iterate_getsmbpwuid(1240)
  unable to open smb password database.

Thanks,

Santiago
