That's strange. So you have Firebird 1.5 Superserver running on
Windows XP. The server is functioning fine, because you can connect to
your database with TCP/IP via localhost. But a local connection fails.

I don't have a solution but I do have a suggestion: try to make a
local connection as Administrator, and/or as the user that owns the
Firebird process (if it isn't Localsystem). That will at least give
you some additional information:

- If Admin can't connect either, the local protocol isn't functioning.
- If he (and/or the Fb process owner) can connect, it must have
something to do with access rights (but access to what?)
