That means the credentials you're entering don't have enough access.

Here you're adding the machine account as root, but are you entering in
root's username and password when adding the machine to the domain?  I'm
not familiar enough with how all the Samba permissions are set up, but I
would guess that your domain admin account doesn't have the access it
should.  If you can add the machine to the domain as the SAMBAPC\root
user or the like then that would definitely be the case.

Cheers,
Adam.
