I'm having some problems generating a new domain for a customer- the facts are that the "landlord" has cut the cable and they can't use the old windows domain as before. I had a Linux Server with Samba there that was a standalone server without ldap, just a file storage.
Now I've "upgradet" it to be a pdc, installed name resolution (DNS from the dhcp) but still get some annoying stuff like " wrong parameter" when trying to add a machine to the domain.

I've googled a lot but never found the exact problem(s) and every try with solutions from other problems don't point in the right direction.
