ok, it seems that you're trying to join a machine already joined..
log in as root
pdbedit -x TES-001-PC$
db accounts delete TES-001-PC$
signal-event ibay-modify Primary
and then try again
P.S: the client machine must not be already joined to a domain; if it is still joined, please unjoin it moving to a workgroup, reboot the client and start over
P.S.2: to join a client to SME you have to use admin's credentials
P.S.3: please, be sure SME is the DNS server for your client and both of them are in the same subnet
