This should not matter unless someone has removed localhost from the
hosts file. By default, a windows box should not even be querying the
DNS server for localhost.

I agree with the rest of the sentiment though. The error message is
the stock standard message you get if you try to connect to a port to
which nothing is listening. The Firebird log clearly states that the
server process crashed, and the initial poster states that this is
during a peak usage time, so to me the error itself is self
explanatory. At the time the particular connection was attempted, the
process was not running because it had just crashed and had not yet
reloaded.

Now you need to work out why the process crashed. Helen gave some
pointers worth considering.
