Using IBExpert (or could be IBO, but just as an example) I change the
database registration 'Server' from 'Remote' to 'Local' and it can not
connect to the datatbase (although the database is local). I change it
to 'Remote' and make the server name 'localhost' and it connects just
fine.

Does this make sense?
