Sounds to me like a firewall issue on your db server machine. Try
'ipchains -L' to see what firewall rules are in effect on the server,

You might also try port scanning from the working and non working
clients (using nmap on un*x, not sure on win/mac) or telneting to the
firebird port ('telnet <db host> 3050') to verify that it isn't an
authentication issue.

luck,
