This sounds like an old version of NAV using classic client. If so, when you do File, Database, Open, there is an Advanced or Options tab (depending on the version) that lists the protocol choices. Usually Default will work, but perhaps you have specific settings on your SQL (or FDB?) server. That client tab needs to match whatever your server has set.
