[Samba] Joining a Linux Machine to a Windows 2003 Active Directory Domain

[C.Peterman]

Hey all, I'm trying to join a Linux machine running CentOS 5, Samba version
3.0.23 to a Windows 2003 Active Directory. I can authenticate successfully
against Kerberos, but I cannot seem to join the domain. I'm using
instructions from this article
http://www.enterprisenetworkingplanet.com/netos/article.php/3487081<https://mymail.clarkson.edu/exchweb/bin/redir.asp?URL=http://www.enterprisenetworkingplanet.com/netos/article.php/3487081>
but when I get to the join command I get this

[root at 0-1-3-1d-38-f2 ~]# net ads join -U adjoin
adjoin's password:
Failed to set password for machine account (NT_STATUS_ACCESS_DENIED)
Failed to join domain!

Any help would be most welcome!
