all known reasons of "unavailable database":
this error can happen when

- client library is not same version as server. Local prococol can be
incompatible even between minor versions of the same server - Firebird
1.5.0, 1.5.1, InterBase 7.0, 7.5.

- you are using local protocol (path to database without server name)
on Windows Vista or 7. To work with local protocol on those OSes you
need
- - InterBase 2007 SP1 and higher
- - Firebird 1.5/2.x with IpcName=Global\FIREBIRD in firebird.conf
- - if IB/FB is started as an application, it may need to be run with
administrative privileges

- client library does not support local protocol at all. For example,
Firebird 1.5.1 for Windows, Classic.

- server is running as a service. So, local protocol may work or may
not work, depends on version of server and client library, and
sometimes on OS version (Windows Vista, Windows terminal servers).

- sometimes reasons why local protocol works on one computer, and not
working on another (looks similar), can't be understood or found.

Also one of the "unavailable database" reasons is specifying
non-existing path to DB. In this case you will get this error even for
the network connection.

p.s. someone can put it into the FAQ, because this is copied from
russian (ibase.ru) FAQ, that helps a lot of people for several years.
