There's an open bug report with the same error:

Is it AD or a NT4 style environment?

Can you join with (if it's AD):
# net ads join -U administrator

I guess DNS, too. Does RPT01 have any special role?

Do you have 'dns_lookup_kdc = true'? Then the lookup for the KDC is done 
via DNS (I don't know if the hardcoded entries are then ignored). It's 
just a guess.
