well from your description then, it would seem as though the message is
coming from the PDC which I am assuming to be samba. Check
/var/log/samba/log.ip_address_of_machine and
/var/log/samba/log.NETBIOS_NAME_OF_MACHINE to see if there are any

On your PDC (is it v3 or 2.2.x?)
domain logons = yes
domain master = yes
preferred master = yes
security = share
os level = ? #not sure if this will cause a problem if less than 32 or


At what point does this error message come - before or after it searches
the domain for a duplicate machine account? If it occurs after it
searches the domain for another machine with the same name, you may want
to delete the machine account from /etc/passwd and /etc/samba/smbpasswd
(or whatever backend you are using... smbpasswd -m -x MACHINE_NAME)
