Apart from to remove a certain piece of software that in my experience
creates more problems than it solves ;)

The active refuse message is generated by the database. From my
experience, it has always been one of two reasons.

1. The service is not running (or at least not listening on that port).
2. There is a firewall blocking that port.

I suppose it is also possible that someone (or some mysterious
software) has set bound the port to a particular NIC.

Try telnet to establish a connection (annoyingly Vista doesn't install
telnet client by default).

telnet [IP Address] 3050

That will remove any Firebird client side issues from the equation.
What you need to see is a black screen, not an error.
